description/ordering information

The ’HC373 devices are octal transparent D-type

GND

latches designed for 2-V to 6-V V

operation.

When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs

are latched at the logic levels of 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) or the 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

interface or pullup components.

OE 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.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
