Product data sheet

1 General description

The 74HC595-Q100; 74HCT595-Q100 is an 8-bit serial-in/serial or parallel-out shift

register with a storage register and 3-state outputs. Both the shift and storage register

have separate clocks. The device features a serial input (DS) and a serial output (Q7S)

to enable cascading and an asynchronous reset MR input. A LOW on MR will reset

the shift register. Data is shifted on the LOW-to-HIGH transitions of the SHCP input.

The data in the shift register is transferred to the storage register on a LOW-to-HIGH

transition of the STCP input. If both clocks are connected together, the shift register will

always be one clock pulse ahead of the storage register. Data in the storage register

appears 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. Operation of the OE input

does not affect the state of the registers. Inputs include clamp diodes. This enables the

use of current limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
