Description

The HCPL-2300 optocoupler

combines an 820 nm AlGaAs

photon emitting diode with an

integrated high gain photon

detector. This combination of

Hewlett-Packard designed and

manufactured semiconductor

devices brings new high

performance capabilities to

designers of isolated logic and

data communication circuits.

The new low current, high speed

AlGaAs emitter manufactured

with a unique diffused junction,

has the virtue of fast rise and fall

times at low drive currents.

Figure 6 illustrates the propaga-

tion delay vs. input current

characteristic. These unique

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to

prevent damage and/or degradation which may be induced by ESD.

characteristics enable this device

to be used in an RS-232-C inter-

face with ground loop isolation

and improved common mode

rejection. As a line receiver, the

HCPL-2300 will operate over

longer line lengths for a given

data rate because of lower IF and

VF specifications.

The output of the shielded inte-

grated detector circuit is an open

collector Schottky clamped tran-

sistor. The shield, which shunts

capacitively coupled common

mode noise to ground, provides a

guaranteed transient immunity

specification of 100 V/µs. The

output circuit includes an

optional integrated 1000 Ω pull-

up resistor for the open collector.

This gives designers the flexibility

to use the internal resistor for

pull-up to five volt logic or to use

an external resistor for connec-

tion to supply voltages up to 18 V

(CMOS logic voltage).

The Electrical and Switching

Characteristics of the HCPL-2300

are guaranteed over a tempera-

ture range of -40°C to 85°C. This

enables the user to confidently

design a circuit which will

operate under a broad range of

operating conditions.

Notes:

1. Bypassing the power supply line is

required with a 0.1 µF ceramic disc

capacitor adjacent to each optocoupler

as illustrated in Figure 19. The power

supply bus for the optocoupler(s)

should be separate from the bus for

any active loads, otherwise a larger

value of bypass capacitor (up to

0.5 µF) may be needed to suppress

regenerative feedback via the power

supply.

2. Peaking circuits may produce transient

input currents up to 100 mA, 500 ns

maximum pulse width, provided

average current does not exceed 5 mA.

Applications

The HCPL-2300 optocoupler has

the unique combination of low

0.5 mA LED operating drive

current at a 5 MBd speed

performance. Low power supply

current requirement of 10 mA

maximum at 5.25 V and the

ability to provide isolation

between logic systems fulfills

numerous applications ranging

from logic level translations, line

receiver and party line receiver

applications, microprocessor I/O

port isolation, etc. The open col-

lector output allows for wired-OR

arrangement. Specific interface

circuits are illustrated in Figures

12-16, and 18 with correspond-

ing component values, perform-

ance data and recommended

layout in Figures 17 and 19.

For -40°C to 85°C operating

temperature range, a mid-range

LED forward current (IF) of

0.625 mA is recommended in

order to prevent overdriving the

integrated circuit detector due to

increased LED efficiency at

temperatures between 0°C and

-40°C. For narrower temperature

range of 0°C to 85°C, a suggested

operating LED current of

0.75 mA is recommended for the

mid-range operating point and for

minimal propagation delay skew.

A peaking capacitance of 20 pF

in parallel with the current

limiting resistor for the LED

shortens tPHL by approximately

33% and tPLH by 13%. Maintain-

ing LED forward voltage (VF)

below 0.8 V will guarantee that

the HCPL-2300 output is off.

The recommended shunt drive

technique for TTL/LSTTL/CMOS

of Figure 12 provides for optimal

speed performance, no leakage

current path through the LED,

and reduced common mode

influences associated with series

switching of a “floating” LED.

Alternate series drive techniques

with either an active CMOS

inverter or an open collector TTL/

LSTTL inverter are illustrated in

Figures 13 and 14 respectively.

Open collector leakage current of

250 µA has been compensated by

the 3.16 KΩ resistor (Figure 14)

at the expense of twice the

operating forward current.

An application of the HCPL-2300

as an unbalanced line receiver for

use in long line twisted wire pair

communication links is shown in

Figure 15. Low LED IF and VF

allow longer line length, higher

speed and multiple stations on

the line in comparison to higher

IF, VF optocouplers. Greater

speed performance along with

nearly infinite common mode

immunity are achieved via the

balanced split phase circuit of

Figure 16. Basic balanced

differential line receiver can be

accomplished with one HCPL-

2300 in Figure 16, but with a

typical 400 V/µs common mode

immunity. Data rate versus

distance for both the above

unbalanced and balanced line

receiver applications are com-

pared in Figure 17. The RS-232-C

interface circuit of Figure 18
