SN74HCT74ADBR

Flip Flops Overview

The SN74HCT74ADBR is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features two independent elements, each with one bit of data storage. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 200 MHz. Key electrical parameters include a propagation delay of 6.6ns at 5V with 50pF load, output currents of 32mA (high) and 64mA (low), and a quiescent current of 250 µA. It utilizes a 14-SSOP package with a width of 5.30mm and functions across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Dual independent D-type positive-edge-triggered flip-flops with preset and clear inputs
• High-speed operation supporting up to 200 MHz clock frequencies
• Low input capacitance for efficient signal integrity
• Complementary output types available in the series

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing and control logic systems
• Memory buffer applications

Flip Flops Procurement Notes

Verify the specific suffix 'ADBR' corresponds to the 14-SSOP package and tape-and-reel or cut-tape packaging options. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid traceability for production processing standards. Cross-reference the part number against official Texas Instruments databases to avoid obsolete or discontinued variants.

Flip Flops Selection Notes

Select this component when dual independent D-type latching is required in a compact surface-mount package. Consider the HCT logic family compatibility with standard TTL voltages. Evaluate the 6.6ns propagation delay against system timing requirements. Verify that the 14-pin SSOP footprint fits the PCB layout constraints compared to alternative packages like SOIC or TSSOP.

Flip Flops Part Context

This part belongs to the SNx4HCT74 series of dual D-type flip-flops. It is distinct from the SN74ABT574, which is an octal flip-flop in a 20-pin package. The HCT series ensures compatibility with 5V CMOS logic levels while maintaining low power consumption. The 'A' prefix often denotes specific manufacturing revisions or enhanced specifications within the product line.

Flip Flops Replacement Considerations

Direct substitutes include SN74HCT74DBR and SN74HCT74N. Check pinout compatibility before substitution. Verify that the replacement part maintains the same 14-SSOP package dimensions. Ensure the alternative meets the same electrical specifications for voltage and temperature ranges.
