SN74AHC74BQAR

Flip Flops Overview

The SN74AHC74BQAR is a dual D-type flip-flop manufactured by Texas Instruments, belonging to the AHC logic family. It features two independent circuits within a single package, each equipped with a clock input, data input, and complementary outputs. The device operates on a single power supply ranging from 2 V to 5.5 V. It utilizes a WQFN-14 surface-mount package suitable for automated assembly. Key electrical specifications include a propagation delay of 6 ns at 3.3 V and output drive currents of ±8 mA. The component supports an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with separate clock and data inputs
• Wide operating voltage range supporting 2 V to 5.5 V supplies
• High-speed performance with low propagation delays
• Complementary outputs for versatile logic interfacing

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations

• General-purpose storage applications

Flip Flops Procurement Notes

Verify the specific ordering suffix 'BQAR' against the manufacturer's official datasheet to confirm the exact package variant and reel quantity. Ensure that the procurement channel provides traceable documentation matching the Texas Instruments part number. Cross-reference the RoHS compliance status and lead time requirements directly with authorized distributors prior to finalizing orders.

Flip Flops Selection Notes

Select this component when a dual D-flip-flop solution is required within space-constrained designs utilizing the WQFN-14 footprint. It is appropriate for systems operating between 2 V and 5.5 V where moderate speed and standard drive capability are sufficient. Consider alternative packages if higher pin counts or different thermal profiles are necessary for the specific application constraints.

Flip Flops Part Context

This part belongs to the SN74AHC series of high-speed CMOS logic devices produced by Texas Instruments. The AHC family offers performance comparable to standard TTL logic but with lower power consumption and wider voltage tolerance. The 'BQAR' suffix indicates a specific tape-and-reel packaging format designed for surface-mount technology assembly processes.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74AHC74DR and SN74AHC74DWR from Texas Instruments, which offer identical logical functionality but utilize SOIC-14 and SSOP-14 packages respectively. Other manufacturers may provide equivalent parts under different naming conventions, requiring verification of pinout compatibility and electrical parameters.
