description
The eight latches of the ’ABT373 are transparent
D-type latches. 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
logic
levels)
or
a
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 SN54ABT373 is characterized for operation over the full military temperature range of –55
°C to 125°C. The
SN74ABT373 is characterized for operation from –40
°C to 85°C.
