SN54ALS564B

SN54ALS564B, SN74ALS564B OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOPS WITH 3-STATE OUTPUTS SDAS164B – APRIL 1982 – REVISED JANUARY 1995 3-State Buffer-Type Inverting Outputs Drive Bus Lines Directly Bus-Structured Pinout Buffered Control Inputs Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), Standard Plastic (N) and Ceramic (J) 300-mil DIPs, and Ceramic Flat (W) Packages 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. SN54ALS564B . . . J OR W PACKAGE SN74ALS564B . . .

FK PACKAGE (TOP VIEW) 1Q VCC OE 1D 2D 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. 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 F...
