description
These octal D-type edge-triggered flip-flops
feature
inverting
3-state
outputs
designed
specifically for bus driving. They are particularly
suitable for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working
registers.
The eight flip-flops enter data on the low-to-high
transition of the clock (CLK) input.
The output-enable (OE) input does not affect
internal operations of the flip-flops. Old data can
be retained or new data can be entered while the
outputs are in the high-impedance state.
The SN54ALS564B is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74ALS564B is characterized for
operation from 0
°C to 70°C.
