74ALVC164245-Q100
16-bit dual supply translating transceiver; 3-state
Rev. 3 — 9 April 2019 Product data sheet
1. General description
The 74ALVC164245-Q100 is a high-performance, low-power, low-voltage, Si-gate CMOS device,
superior to most advanced CMOS compatible TTL families.
The 74ALVC164245-Q100 is a 16-bit (dual octal) dual supply translating transceiver featuring
non-inverting 3-state bus compatible outputs in both send and receive directions. It is designed to
interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment.
This device can be used as two 8-bit transceivers or one 16-bit transceiver.
The direction control inputs (1DIR and 2DIR) determine the direction of the data flow. nDIR (active
HIGH) enables data from nAn ports to nBn ports. nDIR (active LOW) enables data from nBn ports
to nAn ports. The output enable inputs (1OE and 2OE), when HIGH, disable both nAn and nBn
ports by placing them in a high-impedance OFF-state. Pins nAn, nOE and nDIR are referenced to
V
CC(A)
and pins nBn are referenced to V
CC(B)
.
In suspend mode, when one of the supply voltages is zero, there is no current flow from the
non-zero supply towards the zero supply. The nAn outputs must be set 3-state and the voltage on
the A-bus must be smaller than V
diode
(typical 0.7 V). V
CC(B)
≥ V
CC(A)
(except in suspend mode).
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
