Nexperia USA Inc. NPIC6C595D,118

Overview

NPIC6C595D,118 from Nexperia is an 8-bit serial-in/parallel-out shift register with open-drain extended-drain NMOS outputs, separate shift and storage register clocks (SHCP/STCP), asynchronous master reset (MR), and active-low output enable (OE). It delivers 100 mA continuous current per channel, 33 V output clamping, and 30 mJ avalanche energy rating - designed for driving LEDs, relays, and solenoids in industrial status indication systems.

For engineers reviewing the NPIC6C595D,118 datasheet, NPIC6C595D,118 pinout, NPIC6C595D,118 application, or NPIC6C595D,118 equivalent, key selection considerations include its 33 V/100 mA open-drain power outputs, dual-clock architecture enabling independent data latching and shifting, -40 °C to +125 °C operating range, and SO16 package compatibility with legacy PCB layouts.

Technical Context

The device implements two synchronized but functionally independent 8-bit registers: an 8-stage shift register clocked by SHCP and an 8-bit storage register clocked by STCP. Data propagates serially via DS→Q7S and loads into outputs only upon STCP edge, decoupling shift timing from output update timing.

Each of the eight Q0–Q7 outputs integrates an extended-drain NMOS transistor with integrated voltage clamping (33 V breakdown), 250 mA pulsed current capability, and 30 mJ single-pulse avalanche energy tolerance - enabling direct drive of inductive loads without external flyback protection.

Key Specifications

Pinout & Package

FAQ

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

The Q0–Q7 outputs feature integrated 33 V drain-source breakdown voltage (V_(BR)DSS = 33 V min), meaning they safely clamp voltages up to 33 V during inductive flyback events. Continuous load voltage must remain ≤33 V, and absolute maximum V_DS is rated at +33 V - exceeding this risks permanent damage per IEC 60134 limiting values.

Can NPIC6C595D,118 drive 24 V relays directly without external components?

Yes - each output supports 24 V relay coils with up to 100 mA continuous current and withstands 30 mJ avalanche energy, sufficient for typical 24 V DC relays (10–25 mJ coil energy). No external flyback diode is required due to integrated clamping, though layout best practices (short traces, local GND plane) are recommended.

How does the dual-clock architecture improve system timing control?

Separate SHCP (shift) and STCP (storage) clocks allow data to be serially loaded into the shift register while prior data remains latched and active on outputs. A subsequent STCP edge then atomically updates all eight outputs - eliminating partial-state glitches and enabling precise, synchronized display or actuator updates in real-time control loops.

Is NPIC6C595D,118 pin-compatible with other variants like NPIC6C595PW or NPIC6C595BQ?

No - while electrically identical, NPIC6C595D (SO16/SOT109-1), NPIC6C595PW (TSSOP16/SOT403-1), and NPIC6C595BQ (DHVQFN16/SOT763-1) use different physical packages with distinct footprints, thermal pads, and soldering requirements. Board layout and reflow profiles must be tailored to each variant; no mechanical interchangeability exists.
