1 / 17 page SN54AHC595, SN74AHC595 8BIT SHIFT REGISTERS WITH 3STATE OUTPUT REGISTERS SCLS373I − MAY 1997 − REVISED JUNE 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Range 2-V to 5.5-V VCC D 8-Bit Serial-In, Parallel-Out Shift D Shift Register Has Direct Clear D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II D ESD Protection Exceeds JESD 22 − 2000-V Human-Body Model (A114-A) − 200-V Machine Model (A115-A) − 1000-V Charged-Device Model (C101) description/ordering information The ’AHC595 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 registers. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and a serial output for cascading. When the output-enable (OE) input is high, all outputs, except QH′, 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.
