description
These 10-bit latches feature 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 ten latches are transparent D-type. The ’ALS841 and ’AS841 have noninverting data (D) inputs. The
’ALS842 and ’AS842 have inverting D inputs.
