Rev. 4 — 1 October 2018
3.3 V 16-bit buffer/driver with 30 Ω termination resistors;
3-state
Product data sheet
1. General description
The 74LVT162244B is a high-performance BiCMOS product designed for V
CC
operation at 3.3 V.
The 74LVT162244B is designed with 30 Ω series resistance in both the HIGH and LOW states of
the output. This design reduces line noise in applications such as memory address drivers, clock
drivers, and bus receivers/transmitters.
This device is a 16-bit buffer and line driver featuring non-inverting 3-state bus outputs. The device
can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
