DESCRIPTION
The 74LVT162245B is a high-performance BiCMOS product
designed for VCC operation at 3.3V.
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 (nOE) input for
easy cascading and a Direction (DIR) input for direction control.
The 74LVT162245B is designed with 30series 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 transceivers/transmitters.
The 74LVT162245B is the same as the 74LVT16245B-1. The part
number has been changed to reflect industry standards.
