SN74AHCT74RGYR

Flip Flops Overview

The SN74AHCT74RGYR is a dual D-type flip-flop from the Texas Instruments 74AHCT logic family, housed in a 14-VQFN package. It operates with a supply voltage range of 2 V to 5.5 V and features CMOS input/output types. The device supports both inverting and non-inverting polarities and includes preset and clear functions. It exhibits a propagation delay of 15.4 ns, with high-level output current of -8 mA and low-level output current of 8 mA. Operating temperatures range from -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type flip-flop configuration within a compact surface-mount package
• Compatible with standard TTL input levels via AHCT series design
• Includes independent preset and clear control inputs for each flip-flop

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage elements

Flip Flops Procurement Notes

Verify the specific suffix RGYR corresponds to the 14-VQFN package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage with TTL-compatible inputs is required at 5V or lower voltages. The AHCT series ensures compatibility with legacy TTL logic families while offering improved switching characteristics compared to standard LS variants. Verify pinout alignment with existing board layouts due to the VQFN form factor.

Flip Flops Part Context

This part belongs to the SN74AHCT74 series, which provides dual D-type flip-flops with preset and clear. It is part of Texas Instruments' broader 74-series logic portfolio, designed for general-purpose digital applications requiring reliable state retention and fast switching speeds in consumer and industrial electronics.

Flip Flops Replacement Considerations

SN74AHC74RGYR offers similar functionality but with CMOS input thresholds rather than TTL-compatible levels. SN74HCT74D (SOIC) provides equivalent electrical performance in a different package style. Cross-reference datasheets for pinout and timing parameter compatibility before substitution.
