SN74LVTH16373-EP - Enhanced Product 3.3-V Abt 16-Bit Transparent D-Type Latches With 3-State Outputs

The SN74LVTH16373 is a 16-bit transparent D-type latch with tri-state outputs designed for low-voltage (3.3 V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.

This device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. This device 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 low, the Q outputs are latched at the levels set up at the D inputs.
