1. General description

The 74LVT162373 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.

This device is a 16-bit transparent D-type latch with non-inverting 3-state bus compatible outputs.

The device can be used as two 8-bit latches or one 16-bit latch. When latch enable (LE) input is

HIGH, the Q outputs follow the date (D) inputs. When latch enable is taken LOW, the Q outputs are

latched at the levels of the D inputs one setup time prior to the HIGH-to-LOW transition.

The 74LVT162373 is designed with 30 Ω series resistance in both the HIGH-state and LOW-state

of the output. This design reduces the noise in applications such as memory address drivers, clock

drivers and bus receivers and transmitters.
