74ALVT162245
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.
