SN74HC373: Octal Transparent D-Type Latches With 3-State Outputs

Product Information

Features

2-V to 6-V V_CC Operation
Wide Operating Temperature Range of –55°C to 125°C
Balanced Propagation Delays and Transition Times
Standard Outputs Drive up to 15 LS-TTL Loads
Significant Power Reduction Compared to LS-TTL Logic ICs

Description

The ’HC373 devices are octal transparent D-type latches designed for 2-V to 6-V V_CC 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.
