description/ordering information

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 devices 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.
