Description

General part information

SN74LVTH573-EP Series

These octal latches are designed specifically for low-voltage (3.3-V) VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment.

The eight latches of the ’LVTH573 devices are transparent D-type latches. While 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 logic levels set up at the D inputs.

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 increased drive provide the capability to drive bus lines without need for interface or pullup components.
