description
The ’LV373A devices are octal transparent D-type
latches designed for 2-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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV373A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LV373A is characterized for operation from –40
°C to 85°C.
