1. General description

The NPIC6C596-Q100 is an 8-bit serial-in/serial or parallel-out shift register with a storage register

and open-drain 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 resets both the shift register and storage 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 is always one clock pulse ahead of the storage register. To provide

additional hold time in cascaded applications, the serial output QS7 is clocked out on the falling

edge of SHCP. Data in the storage register drives the gate of the output extended-drain NMOS

(EDNMOS) transistor 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.

The open-drain outputs are 33 V/100 mA continuous current extended-drain NMOS transistors

designed for use in systems that require moderate load power such as LEDs. Integrated voltage

clamps in the outputs provide protection against inductive transients making the device suitable for

power driver applications such as relays, solenoids and other low-current or medium-voltage loads.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

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