description
The SN54ABT841 and SN74ABT841A 10-bit
latches are designed specifically for driving highly
capacitive or relatively low-impedance loads.
They are particularly suitable for implementing
buffer registers, I/O ports, bidirectional bus
drivers, and working registers.
The ten transparent D-type latches provide true
data at their outputs.
A buffered output-enable (OE) input can be used
to place the ten outputs in either a normal logic
state
(high
or
low
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.

or
a
OE does not affect the internal operations of the latch. Previously stored data can be retained or new data can
be entered while the outputs are in the high-impedance state.
When V
CC
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, 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.
The SN54ABT841 is characterized for operation over the full military temperature range of –55

SN74ABT841A is characterized for operation from –40
