Description

These solid state display devices

are designed and tested for use in

adverse industrial environments.

The character height is 7.4 mm

(0.29 inch). The numeric and

hexadecimal devices incorporate

an on-board IC that contains the

data memory, decoder and display

driver functions.

The numeric devices decode

positive BCD logic into characters

“0-9”, a “–” sign, decimal point,

and a test pattern. The hexadeci-

mal devices decode positive BCD

logic into 16 characters, “0-9, A-F.”

An input is provided on the hexa-

decimal devices to blank the

display (all LEDs off) without

losing the contents of the memory.

The over range device displays

“–1” and right hand decimal point

and is typically driven via external

switching transistors.

Notes:

1. The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is RθJA = 50°C/W/

device. The device package thermal resistance is RθJ-PIN = 15°C/W/device. The thermal resistance device pin-to-ambient through

the PC board should not exceed 35°C/W/device for operation at T

A = +85°C.

2. Voltage values are with respect to device ground, pin 6.

3. These displays are categorized for luminous intensity with the intensity category designated by a letter code located on the back of

the display package. Case temperature of the device immediately prior to the light measurement is equal to 25°C.

Notes:

4. The luminous intensity at a specific operating ambient temperature, IV (TA) may be approximated from the following exponential

equation: IV (TA = IV (25°C) e[k (T - 25°C)].

5. The dominant wavelength, λd, is derived from the CIE Chromaticity Diagram and is that single wavelength which defines the color of the

device.

6. The HDSP-0860 and HDSP-0960 series devices are categorized as to dominant wavelength with the category designated by a number on

the back of the display package.

Operational

Considerations

Electrical

These devices use a modified

4 x 7 dot matrix light emitting

diode to display decimal/hexa-

decimal numeric information. The

high efficiency red and yellow

LEDs are GaAsP epitaxial layer

on a GaP transparent substrate.

The green LEDs are GaP epitaxial

layer on a GaP transparent

substrate. The LEDs are driven

by constant current drivers, BCD

information is accepted by the

display memory when the enable

line is at logic low and the data is

latched when the enable is at

logic high. Using the enable pulse

width and data setup and hold

times listed in the Recommended

Operating Conditions allows data

to be clocked into an array of

displays at a 6.7 MHz rate.

The decimal point input is active

low true and this data is latched

into the display memory in the

same fashion as the BCD data.

The decimal point LED is driven

by the on-board IC.

The blanking control input on the

hexadecimal displays blanks (turns

off) the displayed information

without disturbing the contents of

display memory. The display is

blanked at a minimum threshold

level of 2.0 volts. When blanked,

the display standby power is

nominally 250 mW at TA = 25°C.

Mechanical

The primary thermal path for

power dissipation is through the

device leads. Therefore, to insure

reliable operation up to an

ambient temperature of +85°C, it

is important to maintain a case-

to-ambient thermal resistance of

less than 35°C watt/device as

measured on top of display pin 3.

For information on soldering and

post solder cleaning see Applica-

tion Note 1027, Soldering LED

Components.

Contrast Enhancement

These display devices are

designed to provide an optimum

ON/OFF contrast when placed

behind an appropriate contrast

enhancement filter. For further

information, please refer to

Application Note 1015, Contrast

Enhancement Techniques for

LED Displays.

Over Range Display

The over range devices display

“±1” and decimal point. The

character height and package

configuration are the same as the

numeric and hexadecimal

devices. Character selection is

obtained via external switching

transistors and current limiting

resistors.
