SCLS041I – DECEMBER 1982 – REVISED SEPTEMBER 2015 SNx4HC595 8-Bit Shift Registers With 3-State Output Registers
1 Features 3 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 3state 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. 1 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
