8-Bit Shift Registers With 3-State Output Registers

 

Description

The SNx4HC595 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.

Features

  • 8-Bit Serial-In, Parallel-Out Shift
  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current 3-State Outputs Can Drive Up to 15
    LSTTL Loads
  • Low Power Consumption: 80-µA (Maximum) ICC
  • tpd = 13 ns (Typical)
  • ±6-mA Output Drive at 5 V
  • Low Input Current: 1 µA (Maximum)

  • On Products Compliant to MIL-PRF-38535,
    All Parameters Are Tested Unless Otherwise
    Noted. On All Other Products, Production
    Processing Does Not Necessarily Include Testing
    of All Parameters.
