MC74LCX16373DT

The MC74LCX16373DT from On Semiconductor is a high-performance, non-inverting 16-bit transparent latch. It operates from a 2.3V to 3.6V supply and is byte-controlled, with separate Output Enable and Latch Enable inputs for each byte, which can be tied together for full 16-bit operation.

This latch features 5.0V tolerant inputs and outputs, allowing for interface capability with 5.0V TTL logic. The maximum propagation delay is 5.4 ns. The device contains 16 D-type latches with 3-state outputs. When the Latch Enable (LEn) inputs are HIGH, data on the Dn inputs enters the latches, making them transparent. When LE is LOW, the latches store the information present at the D inputs.

The outputs are 3-state, controlled by the Output Enable (OEn) inputs. When OE is LOW, the outputs are enabled. When OE is HIGH, the outputs are in a high impedance state. The device supports live insertion and withdrawal, and its IOFF specification guarantees high impedance when VCC is 0V.

Packaged in a 48-TSSOP, this latch is suitable for surface mount applications. It offers LVTTL and LVCMOS compatibility and provides a balanced output sink and source capability of 24 mA. The near-zero static supply current in all three logic states substantially reduces system power requirements.
