description
The ’AHCT573 devices 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.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
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 SN54AHCT573 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74AHCT573 is characterized for operation from –40
°
C to 85
