description
These octal transparent D-type latches are
designed for 2.7-V to 5.5-V VCC operation.
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) 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 need for 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 SN74LV373 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 SN54LV373 is characterized for operation over the full military temperature range of −55°C to 125°C. The
SN74LV373 is characterized for operation from −40°C to 85°C.
