SN74AS74ADBR

Flip Flops Overview

The SN74AS74ADBR is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments. It features independent clear and preset functions for direct control of output states. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports standard CMOS input levels. It is housed in a 14-pin SSOP package suitable for surface-mount applications. The device ensures reliable data storage with low power consumption characteristics typical of the AS logic series.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops
• Independent clear and preset inputs
• Standard CMOS input compatibility

Flip Flops Applications

• Data storage registers
• Shift register construction
• Timing circuit synchronization

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the SSOP-14 package type and tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision history before integration into production designs.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage elements are required within a single package. The AS logic family offers high-speed performance compared to standard TTL equivalents. Consider the 14-pin SSOP footprint for space-constrained PCB layouts. Verify that the operating voltage range aligns with the system's 5 V power supply architecture.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AS series, which represents advanced Schottky logic technology. The SN74AS74AD variant specifically provides two D-type flip-flops with complementary outputs. It is designed for high-speed digital systems requiring fast propagation delays and robust noise immunity in 5 V logic environments.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74AS74AN (PDIP package) or SN74AS74APN (PLCC package). For pin-compatible alternatives, verify the SN74S74ADBR from other manufacturers, ensuring identical electrical specifications and trigger polarity.
