HD74ALVCH16373 Datasheet (Hitachi Semiconductor) - 16-bit Transparent D-type Latches with 3-state Outputs

HD74ALVCH16373, 16-bit Transparent D-type Latches with 3-state Outputs

The HD74ALVCH16373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

It can be used as two 8-bit latches or one 16-bit latch.

When the latch enable (LE) input is high, the Q outputs follow the data (D) inputs.

When LE is taken lo
