Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets

16-bit bus transceiver with direction pin and
30Ω termination resistor (3-State)

1998 Jun 29 853-2085 19638
FEATURES
•Wide supply voltage range of 1.2V to 3.6V
•Complies with JEDEC standard no. 8-1A
•CMOS low power consumption
•MULTIBYTETM flow-through standard pin-out architecture
•Low inductance multiple VCC and ground pins for minimum noise
and ground bounce
•Direct interface with TTL levels
•Bus hold on all data inputs
•Integrated 30Ω termination resistor
DESCRIPTION
The 74ALVCH162245 is a 16-bit transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
The 74ALVCH162245 features two output enable (nOE) inputs for
easy cascading and two send/receive (nDIR) inputs for direction
control. nOE controls the outputs so that the buses are effectively
isolated. This device can be used as two 8-bit transceivers or one
16-bit transceiver.
The 74ALVCH162245 is designed with 30Ω series resistors in both
HIGH and LOW output states.
The 74ALVCH162245 has active bus hold circuitry which is provided
to hold unused or floating data inputs at a valid logic level. This
feature eliminates the need for external pull-up or pull-down
resistors.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V ; (CL × VCC2 × fo) = sum of the outputs.
