SN74ALS564B OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOP

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. SN54ALS564B . . . J OR W PACKAGE SN74ALS564B . . .

Features

e 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. 8D GND CLK 3D 3 2 1 20 19 4 18 2Q 4D 5 17 3Q 5D 6 16 4Q 6D 7 15 5Q 7D 8 14 6Q 9 10 11 12 13 8Q 7Q FUNCTION TABLE (each flip-flop) INPUTS OE CLK D OUTPUT Q L ↑ H L L ↑ L H L L X Q0 H X.
