1 / 9 page SN54HC594, SN74HC594 8-BIT SHIFT REGISTERS WITH OUTPUT REGISTERS SCLS040C – DECEMBER 1982 – REVISED FEBRUARY 1998 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 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 Both Shift and Storage Registers D High-Current Outputs Can Drive Up to 15 LSTTL Loads D Package Options Include Plastic Small-Outline (D), Shrink Small-Outline (DB), and Ceramic Flat (W) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs description The ’HC594 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 (RCLR, SRCLR) inputs are provided on both the shift and storage registers. A serial (QH′) output is provided for cascading purposes. Both the shift register (RCLK) and storage register (SRCLK) clocks are positive edge triggered. If both clocks are connected together, the shift register is always one count pulse ahead of the storage register. The parallel (QA–QH) outputs have high-current capability. QH′ is a standard output. The SN54HC594 is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74HC594 is characterized for operation from –40 °C to 85°C.
