1 / 17 page SN54AHC594, SN74AHC594 8BIT SHIFT REGISTERS WITH OUTPUT REGISTERS SCLS423F − JUNE 1998 − REVISED SEPTEMBER 2003 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 Registers With Storage D Independent Direct Overriding Clears on Shift and Storage Registers D Independent Clocks for Shift and Storage Registers 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 ’AHC594 devices contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clear (SRCLR, RCLR) inputs are provided on the shift and storage registers. A serial (QH′) output is provided for cascading purposes. The shift register (SRCLK) and storage register (RCLK) clocks are positive-edge triggered. If the clocks are tied together, the shift register always is one clock pulse ahead of the storage register.
