Nexperia USA Inc. NPIC6C596D,118

Overview

NPIC6C596D,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 asynchronous master reset (MR). It drives moderate-power loads such as LED signage, relay coils, and solenoids in industrial control panels and fault indicator systems.

For engineers reviewing the NPIC6C596D,118 datasheet, NPIC6C596D,118 pinout, NPIC6C596D,118 application, or NPIC6C596D,118 equivalent, key selection criteria include output voltage clamping (33 V), avalanche energy rating (30 mJ), cascading capability via Q7S, dual-clock timing independence (SHCP/STCP), and operation across –40 °C to +125 °C.

Technical Context

The device implements two synchronized but independent 8-bit registers: an 8-stage shift register clocked by SHCP (LOW-to-HIGH edge) and a storage register clocked by STCP (LOW-to-HIGH edge), enabling precise staging of data transfer and output latching. Serial cascading is supported via DS input and Q7S output, with Q7S timed on the falling edge of SHCP to extend hold time.

Each of the eight outputs integrates an EDNMOS transistor with internal voltage clamping (V_(BR)DSS = 33 V), 30 mJ single-pulse avalanche energy capability, and R_DS(on) ≤ 10 Ω at 50 mA and 25 °C. Output enable (OE, active LOW) places outputs in high-impedance OFF-state without affecting register contents.

FAQ

What is the maximum safe operating voltage on the Q0–Q7 outputs?

The NPIC6C596D,118 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; exceeding this risks permanent avalanche-induced failure. For inductive loads, the integrated 30 mJ avalanche energy rating allows safe clamping of transients up to that energy level, provided layout minimizes parasitic inductance.

Can NPIC6C596D,118 drive multiple LEDs in parallel per output?

Yes-each Q0–Q7 output can sink up to 100 mA continuously. At typical red/green LED forward voltage (~2.0 V) and 5 V V_CC, up to four 20 mA LEDs may be paralleled per channel if R_DS(on) remains ≤10 Ω (verified at 25 °C). Derating is required above 85 °C ambient; consult Fig. 17 for R_DS(on) vs. temperature.

How does the dual-clock (SHCP/STCP) architecture prevent output glitches?

SHCP shifts data into the internal shift register without affecting outputs; STCP separately latches that data into the storage register, which directly drives the outputs. This separation ensures outputs change only on STCP edges-eliminating spurious transitions during serial loading. When SHCP and STCP are tied, outputs update one clock after data entry, but independent routing is preferred for deterministic timing.

Is NPIC6C596D,118 pin-compatible with other Nexperia shift registers like the 74HC595?

No-NPIC6C596D,118 uses a distinct pinout optimized for power driving: Q0–Q7 occupy pins 3–6 and 11–14, OE is on pin 8, and Q7S is on pin 9. In contrast, 74HC595 places outputs Q0–Q7 on pins 15–7 (sequential), has no OE or Q7S, and lacks power-rated outputs. Direct replacement requires PCB redesign and firmware adaptation for OE and MR control.
