74HC594 8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER Description Pin Assignments The 74HC594 is a high speed CMOS device. ( Top View ) An eight bit shift register accepts data from the serial input (DS) on Q1 1 16 Vcc asserted low, the shift regisister reset function (SHR) sets all shift Q2 2 15 Q0 register values to zero and is independent of all clocks. Also when Q3 3 14 DS Q4 4 13 STR Q5 5 12 STCP The Q6 6 11 SHCP storage resister includes output Q7S which is used for cascading Q7 7 10 SHR 8 9 Q7S each positive transition of the shift register clock (SHCP). When asserted low, the storage register reset function (STR) sets all shift register values to zero and is independent of all clocks. Data from the input serial shift register is placed in the output register with a rising pulse on the storages resister clock (STCP). information between devices. As the information moves into the GND storage register, it is asserted on the push-pull outputs Q0-Q7. SO-16 / TSSOP-16 All registers capture data on rising edge and change output on the falling edge. If both clocks are connected together, the input shift register is always one clock cycle ahead of the output register.
