description

This 8-bit latch features 3-state outputs designed to sink up to 12 mA, and include 25- sink resitors to reduce overshoot and undershoot.

The eight latches of the SN74F2373 are transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When the LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs.

A buffered output-enable () 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.

input does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

The SN74F373 is available in TI's shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN74F373 is characterized for operation from 0°C to 70°C.
