General description

The 74ALVC164245 is a high-performance, low-power, low-voltage, Si-gate CMOS

device, superior to most advanced CMOS compatible TTL families.

The 74ALVC164245 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 nA ports to nB ports. nDIR (active LOW) enables

data from nB ports to nA ports. The output enable inputs (1OE and 2OE), when HIGH,

disable both nA and nB ports by placing them in a high-impedance OFF-state. The nB

ports interface with the 5 V bus. The nA ports interface with the 3 V bus.

In suspend mode, when one of the supply voltages is zero, there will be no current flow

from the non-zero supply towards the zero supply. The A-outputs must be set 3-state and

in suspend mode).
