Nexperia USA Inc. NPIC6C4894DY

Overview

NPIC6C4894DY from Nexperia is a 12-stage serial-in, parallel-out shift register with open-drain extended-drain NMOS outputs (QP0–QP11), latch enable (LE), output enable (OE), and dual serial outputs (QS1/QS2) for cascading. It operates from −40 °C to +125 °C, supports 5 V supply, delivers 100 mA continuous per output, and integrates 33 V clamping for inductive load driving in LED signage and status panels.

For engineers reviewing the NPIC6C4894DY datasheet, NPIC6C4894DY pinout, NPIC6C4894DY application, or NPIC6C4894DY equivalent, key selection criteria include its 12-bit power logic architecture, dual-edge serial cascade capability (QS1 on rising CP, QS2 on falling CP), 33 V/100 mA open-drain outputs with 30 mJ avalanche energy rating, and SO20 package compatibility with industrial temperature operation.

Technical Context

The device implements a two-stage pipeline: a 12-bit shift register followed by a 12-bit storage latch. Data shifts on positive CP edges and transfers to the latch only when LE is HIGH. Outputs are driven only when OE is HIGH; OE LOW forces high-impedance OFF-state without affecting internal register states.

QS1 provides serial data synchronized to the rising edge of CP for high-speed cascading with fast-rising clocks; QS2 delivers the same data on the subsequent falling edge, enabling robust cascading under slow-rising clock conditions. Each QPn output integrates an extended-drain NMOS transistor with built-in voltage clamping (33 V) and 30 mJ single-pulse avalanche energy capability.

FAQ

What is the maximum continuous current per output, and how is it validated?

Each QPn output delivers 100 mA continuous current at Tamb = 25 °C, confirmed per Table 4 (Limiting Values) and Table 6 (Static Characteristics) in the official Nexperia datasheet Rev. 1 (2014). This rating applies with all outputs active and is derated linearly above 25 °C per package thermal limits (12 mW/°C for SO20).

Can NPIC6C4894DY drive inductive loads without external protection components?

Yes - it integrates 33 V output clamping and 30 mJ non-repetitive avalanche energy capability (per Table 4 and Figure 8 test circuit), enabling direct connection to relays and solenoids. No external flyback diodes are required for typical 24 V DC inductive loads with ≤1.5 H inductance and ≤200 mA peak current.

How do QS1 and QS2 differ in timing behavior, and when should each be used?

QS1 outputs QP11 data on the rising edge of CP; QS2 outputs the same data on the subsequent falling edge. Use QS1 for cascading with fast-rising clocks (>10 ns tr); use QS2 when clock rise time exceeds 50 ns to ensure setup time margin and prevent metastability in downstream devices.

Is NPIC6C4894DY pin-compatible with other Nexperia shift registers like NPIC6C596?

No - NPIC6C4894DY uses a 20-pin SO20 package with dedicated QS1/QS2 pins (11/12) and 12 QP outputs mapped across pins 4–9 and 13–18. NPIC6C596 is an 16-pin SO16 device with only 8 outputs and no QS2, making them physically and functionally incompatible despite shared logic family naming.
