74AHCT74PW,112

Overview

The 74AHCT74PW,112 is a dual D-type flip-flop with set and reset functions from the Nexperia 74AHCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device provides positive-edge triggered data transfer with asynchronous active-low set and reset inputs. It is housed in a 14-SO (Small Outline) surface-mount package and supports an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Dual D-type flip-flops with individual set and reset controls
• TTL-compatible input levels for direct interface with 74HC logic
• Asynchronous active-low set and reset inputs independent of clock
• Positive-edge triggering for predictable data transfer

Applications

• Data storage and latching circuits
• Shift register construction
• Frequency division and counting applications
• Digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications regarding manufacturing site transfers or marking updates. Validate package integrity against specified 14-SO dimensions prior to assembly integration.

Selection Notes

Select this component when TTL-level interfacing is required with AHCT performance characteristics. Ensure design requirements align with the 4.5 V to 5.5 V supply voltage constraints. Consider the 14-SO package footprint for PCB layout compatibility and verify thermal management capabilities for the specified industrial temperature range.

Part Context

This part belongs to the 74AHCT family, which combines the high-speed performance of AHC technology with CMOS power consumption while maintaining TTL-compatible input thresholds. The 74AHCT74 variant specifically integrates two independent D-type flip-flops with set and reset functionality into a single compact package, suitable for complex digital logic designs.

Replacement Considerations

Consider 74AHCT74PW,118 as a potential alternative with identical electrical specifications but different packaging configuration. Verify pinout compatibility and ensure that any substitute maintains the same TTL input level requirements and asynchronous control functionality.
