DESCRIPTION
The 74ALVCH162245 is a 16-bit transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
36
2A0
The 74ALVCH162245 features two output enable (nOE) inputs for
easy cascading and two send/receive (nDIR) inputs for direction
control. nOE controls the outputs so that the buses are effectively
isolated. This device can be used as two 8-bit transceivers or one
16-bit transceiver.

The 74ALVCH162245 is designed with 30Ω series resistors in both
HIGH and LOW output states.

The 74ALVCH162245 has active bus hold circuitry which is provided
to hold unused or floating data inputs at a valid logic level. This
feature eliminates the need for external pull-up or pull-down
resistors.

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
