Description

These  SN54ALS564B and SN74ALS564B octal D-type edge-triggered flip-flops feature inverting 3-state outputs designed specifically for bus driving. SN54ALS564B and SN74ALS564B  are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The SN54ALS564B and SN74ALS564B  eight flip-flops enter data on the low-to-high transition of the clock (CLK) input.

The output-enable (OE) input of SN54ALS564B and SN74ALS564B  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.
