74AHCT74BQ,115

Overview

The 74AHCT74BQ,115 is a dual D-type edge-triggered flip-flop manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and features differential outputs with inverting and non-inverting polarities. The device supports single-ended inputs and provides high-level output currents of -8 mA and low-level currents of 8 mA. Propagation delay is specified at 3.3 ns. It is housed in a DHVQFN-14 surface-mount package and functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Dual D-type edge-triggered flip-flops with complementary differential outputs
• Compatible with standard 5 V CMOS logic families via AHCT series specifications
• High noise immunity and fast switching characteristics for digital signal processing

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• Timing and synchronization control systems

Procurement Notes

Verify the specific suffix '115' corresponds to the DHVQFN-14 package variant during procurement. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature limits. Ensure power supply stability between 4.5 V and 5.5 V to maintain correct logic thresholds. Check datasheet revisions for any recent product change notifications affecting assembly sites or labeling.

Selection Notes

Select this component when a dual flip-flop solution with differential outputs is required for 5 V logic interfaces. It is suitable for designs needing fast propagation delays and robust performance in high-temperature environments. Consider the DHVQFN-14 package size constraints and thermal dissipation requirements relative to the 500 mW power dissipation rating.

Part Context

This part belongs to the Nexperia 74AHCT logic family, designed for operation with 5 V CMOS devices while accepting TTL-compatible input levels. The '74' designation indicates a dual configuration, and 'HCT' specifies High-speed CMOS technology compatible with 5 V supplies. The 'BQ' suffix denotes the specific DHVQFN surface-mount package type used in compact electronic assemblies.
