16-bit transceiver with 30 Ω termination resistors; 3-state

Rev. 3 — 29 January 2018

Product data sheet

1 General description

The 74ALVT162245 is a high-performance BiCMOS product designed for VCC operation

at 2.5 V or 3.3 V with I/O compatibility up to 5 V.

This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs

in both send and receive directions. The control function implementation minimizes

external timing requirements. The device features an output enable input (nOE) for easy

cascading and a direction control input (nDIR) for direction control.

The 74ALVT162245 is designed with 30 Ω series resistance in both the HIGH-state and

LOW-state of the output. This design reduces line noise in applications such as memory

address drivers, clock drivers and bus transceivers and transmitters.
