Nexperia USA Inc. NPIC6C596ADJ

Overview

NPIC6C596ADJ 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 / 100 mA continuous current per channel, integrated output clamping, and operation from -40 °C to +125 °C. It drives LED signage, fault indicators, and graphic status panels via cascaded power logic control.

For engineers reviewing the NPIC6C596ADJ datasheet, NPIC6C596ADJ pinout, NPIC6C596ADJ application, or NPIC6C596ADJ equivalent, this page delivers verified functional architecture, real-world timing behavior (SHCP→Q7S propagation ≤5 ns), avalanche energy rating (30 mJ), R_DS(on) at 3.0 V (3.1–12 Ω), and SO16 package compatibility - all critical for industrial LED driver and relay interface design.

Technical Context

The device implements dual-clock synchronous logic: SHCP controls 8-stage serial shifting (data entered at DS, output at Q7S on falling edge), while STCP latches data into the 8-bit storage register. MR asynchronously clears both registers. OE enables/disables all outputs independently without affecting internal state.

Each of the eight Q0–Q7 outputs integrates a rugged EDNMOS transistor with 33 V drain-source breakdown, 250 mA pulsed current capability, and built-in voltage clamping to suppress inductive transients from relays or solenoids - enabling direct drive of medium-voltage loads without external flyback diodes.

FAQ

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

The NPIC6C596ADJ outputs feature extended-drain NMOS transistors with a minimum drain-source breakdown voltage (V_(BR)DSS) of 33 V. Absolute maximum rating is 33 V continuous - applying higher voltages risks permanent avalanche failure. For 24 V relay coils, ensure clamping remains within spec by verifying worst-case inductive spike amplitude does not exceed 33 V.

Can NPIC6C596ADJ drive multiple LEDs in series per channel?

No - each Q0–Q7 output is open-drain and designed to sink current from a single load node to ground. To drive series LEDs, connect the LED string anode to a fixed positive rail (≤33 V), cathode to the output pin, and rely on the IC's 100 mA continuous rating. Series configuration requires matching forward voltage sum ≤ rail voltage minus dropout.

How does the Q7S falling-edge timing improve cascaded performance?

Q7S updates on the falling edge of SHCP - providing additional setup time for the DS input of the next device in the chain. This compensates for propagation delays in long trace runs or high-capacitance interconnects, enabling reliable operation at >8 MHz cascade frequency where standard rising-edge Q7S would violate setup timing.

Is the DHVQFN16 package (NPIC6C596ABQ) pin-compatible with the SO16 version?

No - while both packages contain 16 terminals and implement identical logic, the pin mapping differs significantly. SO16 (NPIC6C596AD) uses standard DIP-style numbering; DHVQFN16 (NPIC6C596ABQ) has different pin assignments (e.g., GND is Pin 1 in DHVQFN vs. Pin 16 in SO16). PCB layout and schematic symbols must be redesigned for package interchange.
