The 'LVTH162373 devices are16-bit transparent D-type latches with 3-state outputs designed for low-voltage (3.3-V) VCCoperation, 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.

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without interface or pullup components.

OEdoes not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.Read more
