NPIC6C596PW,118

Shift Registers Overview

The NPIC6C596PW,118 is an 8-bit serial-in/serial or parallel-out shift register with open-drain outputs. It features separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. The device includes an asynchronous reset (MR) and an output enable (OE) input. The open-drain outputs are 33 V/100 mA continuous current extended-drain NMOS transistors designed for moderate load power applications like LEDs. Integrated voltage clamps protect against inductive transients.

Shift Registers Feature Summary

• Eight Power EDNMOS transistor outputs providing 100 mA continuous current capability
• Output clamping voltage of 33 V with 30 mJ avalanche energy capability
• Enhanced cascading functionality for multiple stages using serial output Q7S
• All registers cleared with a single asynchronous master reset input

Shift Registers Applications

• LED sign
• Graphic status panel
• Fault status indicator

Shift Registers Procurement Notes

Verify the specific ordering suffix ',118' against the manufacturer's official documentation to confirm packaging details and availability status. Confirm that the TSSOP16 package variant matches the design requirements. Check for any product change notices or end-of-life announcements associated with this specific part number before finalizing procurement plans.

Shift Registers Selection Notes

Select this component for designs requiring high-current open-drain outputs driven by a serial interface. Ensure the supply voltage range of 4.5 V to 5.5 V aligns with the system power rails. Verify that the operating temperature range of -40 °C to +125 °C meets environmental constraints. Consider the low RDSon characteristics for efficient power handling in LED or relay driver applications.

Shift Registers Part Context

The NPIC6C596 belongs to Nexperia's Power Logic family, specifically designed as an 8-bit shift register with integrated power outputs. It combines standard logic shifting capabilities with robust power switching features, making it suitable for direct driving of loads without additional buffer components. The TSSOP16 package offers a compact solution for space-constrained PCB layouts.

Shift Registers Replacement Considerations

Check for alternative packages within the same NPIC6C596 family, such as SO16 or DHVQFN16, if pin compatibility allows. Verify functional equivalence with other 8-bit shift registers featuring open-drain outputs if the specific NPIC6C596 is unavailable.

Shift Registers FAQ

How does the serial output Q7S enhance cascading?

The serial output Q7S is clocked out on the falling edge of SHCP, providing additional hold time in cascaded applications to ensure reliable data transfer between multiple stages.

What is the function of the OE input?

The Output Enable (OE) input controls the state of the open-drain outputs. A LOW on OE allows the storage register data to drive the outputs, while a HIGH causes the outputs to assume a high-impedance OFF-state without affecting the register states.
