NPIC6C4894DY

Shift Registers Overview

The NPIC6C4894DY is a power logic 12-bit serial shift register with open-drain outputs manufactured by Nexperia. It features 12 extended-drain NMOS transistors capable of 100 mA continuous current and 250 mA current limit capability. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. Data shifts on positive-going clock transitions, with storage latches strobing data to parallel outputs when the latch enable input is HIGH. Integrated voltage clamps provide protection against inductive transients.

Shift Registers Feature Summary

• Provides 12 parallel open-drain outputs using extended-drain NMOS technology for moderate load power applications.
• Includes integrated voltage clamps to protect against inductive transients, suitable for driving relays and solenoids.
• Features two serial outputs (QS1 and QS2) to facilitate cascading devices based on clock rise time characteristics.
• Offers robust ESD protection exceeding 2500 V under Human Body Model conditions.

Shift Registers Applications

• LED sign displays
• Graphic status panels
• Fault status indicators

Shift Registers Procurement Notes

Verify the specific package variant required, as the 'DY' suffix typically denotes the SO20 plastic small outline package (SOT163-1). Confirm that the application does not require automotive qualification, as this product is not AEC-Q100 qualified. Ensure design margins account for the specified operating temperature range and power dissipation derating curves provided in the datasheet.

Shift Registers Selection Notes

Select this component for designs requiring serial-to-parallel conversion with direct drive capabilities for medium-voltage loads. The open-drain architecture allows interfacing with various voltage levels up to the drain-source breakdown limit. Consider the propagation delay and maximum clock frequency specifications when designing high-speed serial data paths or cascaded configurations.

Shift Registers Part Context

This part belongs to the NPIC6C4894 family of power logic shift registers. It is distinct from standard logic shift registers due to its integrated power output stage. The device serves as a bridge between low-power control logic and higher-current loads, eliminating the need for external driver transistors in many LED and relay control scenarios.
