NPIC6C596PW-Q100,1

Shift Registers Overview

The NPIC6C596PW-Q100,1 is an automotive-grade 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 master reset (MR) and an active-low output enable (OE). Packaged in TSSOP16 (SOT403-1), it operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C.

• Eight power EDNMOS transistor outputs capable of 100 mA continuous current
• Integrated voltage clamps providing protection against inductive transients
• Enhanced cascading capability with serial output clocked on the falling edge

Shift Registers Applications

• LED sign drivers
• Graphic status panels
• Fault status indicators

Shift Registers Procurement Notes

Verify the specific suffix '1' corresponds to the standard tape-and-reel packaging configuration as defined in the official Nexperia ordering information. Confirm that the TSSOP16 package variant matches the required board layout dimensions. Ensure design compliance with the specified 4.5 V to 5.5 V supply voltage limits for reliable operation.

Shift Registers Selection Notes

Select this component when driving moderate load power requirements such as LEDs, relays, or solenoids directly from logic outputs. The open-drain architecture allows for flexible voltage level shifting and common-ground configurations. Consider the low RDSon characteristics for efficient power handling in space-constrained automotive designs requiring high reliability.

Shift Registers Part Context

This part belongs to the NPIC6C596-Q100 family of power logic shift registers manufactured by Nexperia. It is specifically designed for automotive applications, offering robust performance under harsh environmental conditions. The family includes alternative packages such as SO16 and DHVQFN16, providing design flexibility for different thermal and spatial constraints while maintaining identical electrical functionality.

Shift Registers Replacement Considerations

Direct substitutes include other NPIC6C596 variants with different package footprints, such as NPIC6C596D-Q100 (SO16) or NPIC6C596BQ-Q100 (DHVQFN16), provided the mechanical interface can be adapted. Non-Nexperia equivalents require careful verification of pinout compatibility, current capabilities, and automotive qualification status.

Shift Registers FAQ

How does the serial output (Q7S) enhance cascading applications?

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

What is the function of the integrated voltage clamps in the outputs?

The integrated voltage clamps protect the extended-drain NMOS transistors against inductive transients, making the device suitable for driving inductive loads like relays and solenoids without external protection components.
