Nexperia 74HCS595 8-bit Shift Register
Nexperia 74HCS595 8-bit Shift Register offers a storage register and 3-state outputs, with the shift and storage register supplying separate clocks. The 8-bit serial-in/serial or parallel-out shift register provides a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous reset MR input. Furthermore, a LOW on MR will reset the shift register, and data is shifted on the LOW-to-HIGH transitions of the SHCP input.
If both clocks are connected, the shift register will consistently be one clock pulse ahead of the storage register. Data in the storage register materializes at the output whenever the output enable input (OE) is LOW. A HIGH on OE causes the outputs to assume a high-impedance OFF state, and the operation of the OE input does not affect the state of the registers. The inputs include clamp diodes, which allow the use of current-limiting resistors to interface inputs to voltages in excess of VCC. All inputs are Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
