The 'AHC373 are octal transparent D-type latches.
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.
The SN54AHC373 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AHC373 is characterized for operation from -40°C to 85°C.
