Nexperia USA Inc. NPIC6C596PW,118

Overview

NPIC6C596PW,118 from Nexperia is an 8-bit serial-in/parallel-out shift register with separate shift and storage register clocks, open-drain extended-drain NMOS (EDNMOS) outputs rated for 33 V and 100 mA continuous current per channel, and integrated 30 mJ avalanche energy protection - used in LED signage, fault indicator panels, and relay/solenoid driver stages where moderate load power and inductive transient resilience are required.

For engineers reviewing the NPIC6C596PW,118 datasheet, NPIC6C596PW,118 pinout, NPIC6C596PW,118 application, or NPIC6C596PW,118 equivalent, key selection criteria include its dual-clock architecture (SHCP/STCP), asynchronous master reset (MR), active-low output enable (OE), cascading-capable Q7S output, and TSSOP16 package thermal performance at -40 °C to +125 °C.

Technical Context

The device implements two independent synchronous registers: an 8-stage shift register clocked on SHCP rising edge and a parallel storage register loaded on STCP rising edge - enabling precise timing separation between data shifting and output latching. Its open-drain EDNMOS outputs feature internal source-to-GND connection and built-in voltage clamping to 33 V, eliminating external flyback diodes in inductive load switching.

Operation is fully static: MR asynchronously clears both registers; OE independently controls output high-impedance state without affecting register contents; Q7S serial output is edge-aligned to SHCP falling edge to extend hold time in multi-stage daisy chains - critical for reliable inter-device data transfer at up to 10 MHz.

FAQ

What is the maximum safe voltage that can be applied to the Q0–Q7 outputs?

The NPIC6C596PW,118 outputs are rated for a maximum drain-source voltage (V_DSS) of 33 V, with a typical breakdown voltage of 37 V. Continuous operation above 33 V risks permanent damage; transient spikes must remain within the 30 mJ avalanche energy limit defined in the datasheet under controlled test conditions.

Can NPIC6C596PW,118 drive 12 V relays directly without external components?

Yes - each Qn output can sink up to 100 mA continuously at 12 V, and the integrated 33 V clamp protects against relay coil back-EMF. No external flyback diode is required, though a 100 nF ceramic capacitor near VCC and local GND routing is recommended for noise immunity.

How does the Q7S output timing differ from standard shift register serial outputs?

Unlike conventional shift registers where Q7S updates on SHCP rising edge, NPIC6C596PW,118 clocks Q7S on the SHCP falling edge - providing additional setup time for the next stage's DS input in cascaded configurations, improving timing margin by ≥40 ns at 10 MHz operation.

Is the TSSOP16 package (SOT403-1) thermally adequate for sustained 100 mA per channel operation?

At 25 °C ambient, the TSSOP16 package supports 725 mW total power dissipation. With eight channels at 100 mA and typical R_DS(on) of 3.1 Ω, total power is ~250 mW - well within limits. Derating is linear at 5.8 mW/°C above 25 °C, supporting full-load operation up to ~85 °C ambient with standard PCB copper area.
