description
The
′ABT841 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 latches are transparent D-type latches.
The device has noninverting data (D) inputs and
provides true data at its outputs.
A buffered output-enable (OE) input can be used
to place the ten outputs in either a normal logic
state (high or low 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 latch. Previously stored 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 SN74ABT841 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 SN54ABT841 is characterized for operation over the full military temperature range of – 55
°C to 125°C. The
SN74ABT841 is characterized for operation from – 40
°C to 85°C.
