Nexperia USA Inc. NPIC6C596APWJ

Overview

NPIC6C596APWJ from Nexperia is an 8-bit serial-in/parallel-out power logic shift register with open-drain extended-drain NMOS (EDNMOS) outputs, separate shift/storage 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 integrated avalanche energy protection (30 mJ), enabling direct driving of LEDs, relays, and solenoids in industrial status panels and signage.

For engineers reviewing the NPIC6C596APWJ datasheet, NPIC6C596APWJ pinout, NPIC6C596APWJ application, or NPIC6C596APWJ equivalent, key selection criteria include its 2.3–5.5 V supply range, -40 °C to +125 °C operation, cascading-capable Q7S output clocked on SHCP falling edge, and verified 10 MHz maximum shift clock frequency under 75 mA load conditions.

Technical Context

The device implements dual-register architecture: an 8-stage shift register clocked by SHCP (data shifted on LOW-to-HIGH transition) and a parallel storage register clocked by STCP (data latched on LOW-to-HIGH transition). This separation enables precise timing control in cascaded configurations and eliminates race conditions during data transfer.

Each of the eight Q0–Q7 outputs integrates an EDNMOS transistor with 33 V drain-source breakdown voltage, 0.002–0.2 μA drain cut-off current at 125 °C, and R_DS(on) ranging from 3.1 Ω (V_CC = 3.0 V, I_D = 100 mA, T_amb = 25 °C) to 14 Ω at 125 °C - enabling robust switching of moderate-power loads without external flyback protection.

FAQ

Can NPIC6C596APWJ drive 24 V LED strings directly?

Yes - its 33 V output clamping voltage and 100 mA continuous per-channel rating allow direct sinking of common-anode 24 V LED strings. External current-limiting resistors must be sized for the target forward current and supply voltage; no additional flyback protection is needed due to integrated avalanche energy handling (30 mJ).

What is the minimum setup/hold time required for DS relative to SHCP?

The datasheet specifies 15 ns minimum setup time (t_su) and 15 ns minimum hold time (t_h) for DS relative to SHCP rising edge. These values are guaranteed across -40 °C to +125 °C and ensure reliable data capture even at the 10 MHz maximum clock frequency, provided PCB trace lengths are matched and signal integrity is maintained.

Does OE affect the state of the shift or storage registers?

No - the OE (output enable) input controls only the output stage impedance and has no effect on the contents of either the shift register or the storage register. When OE is HIGH, all Q0–Q7 outputs enter high-impedance OFF-state while register data remains intact, enabling safe hot-swap or shared-bus operation without disrupting ongoing serial loading.

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

Q7S is clocked on the falling edge of SHCP - unlike standard shift register outputs that align with the rising edge. This intentional phase offset provides additional hold time (typically 10–20 ns) for the serial data to settle before being sampled by the next device in a cascade, improving timing margin in multi-stage daisy-chain configurations without requiring external delay elements.
