8-bit serial-in, serial or parallel-out shift register with output latches and 3-state outputs. Separate shift and storage register clocks (SHCP/STCP) allow gated update of the parallel outputs, and Q7S enables cascading. Wide 2.0-6.0 V CMOS supply, ~100 MHz typical shift-out frequency. 74HC595BQ >NAME >VALUE >NAME >VALUE GPIO GROUND CONTROL TIMING POWER 8-bit serial-in, serial or parallel-out shift register with output latches and 3-state outputs.
