1 / 20 page SN54HC595, SN74HC595 8BIT SHIFT REGISTERS WITH 3STATE OUTPUT REGISTERS SCLS041G − DECEMBER 1982 − REVISED FEBRUARY 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 8-Bit Serial-In, Parallel-Out Shift D Wide Operating Voltage Range of 2 V to 6 V D High-Current 3-State Outputs Can Drive Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 13 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Shift Register Has Direct Clear description/ordering information The ’HC595 devices contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the outputs are in the high-impedance state. Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If both clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
