SN54ALVTH32373 - 32-BIT TRANSPARENT D-TYPE LATCHES

General Description

The ’ALVTH32373 devices are 32-bit transparent D-type latches with 3-state outputs designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

These devices can be used as four 8-bit latches, two 16-bit latches, or one 32-bit latch.
