description
These 20-bit transparent D-type latches feature
noninverting 3-state outputs 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 ’ABT162841 can be used as two 10-bit latches or one 20-bit latch. While the latch-enable (1LE or 2LE) input
is high, the Q outputs of the corresponding 10-bit latch follow the data (D) inputs. When LE is taken low, the
Q outputs are latched at the levels set up at the D inputs.
A buffered output-enable (1OE or 2OE) input can be used to place the outputs of the corresponding 10-bit latch
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 outputs, which are designed to sink up to 12 mA, include equivalent 25-
series resistors to reduce
overshoot and undershoot.
OE does not affect the internal operation of the latches. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
