Overview
The Nexperia 74HCT112D-Q100J is a dual negative-edge triggered JK flip-flop housed in a SOIC-14 package. It features individual J and K inputs, clock (nCP), asynchronous active LOW set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40 °C to +125 °C. It is qualified to AEC-Q100 Grade 1 standards for automotive applications.
Feature Summary
- Dual negative-edge triggered JK flip-flops with independent control inputs
- Asynchronous active LOW set and reset functions operating independently of the clock
- Schmitt-trigger action on the clock input for tolerance to slow signal transitions
- Automotive qualification compliant with AEC-Q100 Grade 1 standards
Applications
- Automotive electronic systems requiring robust logic control
- Industrial applications utilizing mixed voltage interfaces
- Data storage and shift register circuits
Procurement Notes
Verify the specific suffix 'J' against the manufacturer's official documentation to confirm packaging details, as ordering suffixes may indicate variations in tape and reel specifications or regional compliance markings. Ensure the procurement source provides valid traceability and authenticity guarantees consistent with Nexperia's authorized distribution channels.
Selection Notes
Select this component when dual JK flip-flop functionality with asynchronous set and reset is required in space-constrained designs. The HCT series ensures TTL-compatible input levels, facilitating integration with legacy digital systems. The wide temperature range and automotive qualification make it suitable for harsh environments where standard commercial grade parts are insufficient.
Part Context
This part belongs to the Nexperia 74HCT family of high-speed CMOS logic devices. It is specifically designed for automotive and industrial sectors, offering enhanced reliability compared to standard commercial variants. The device integrates well into complex digital logic architectures requiring state retention and sequential control capabilities.
Replacement Considerations
Compatible substitutes include the 74HC112D-Q100J for CMOS-level input compatibility and generic 74HCT112 equivalents from other manufacturers, provided pinouts and electrical characteristics match the SOIC-14 form factor and functional requirements.
