MC74AC74DTR2

Flip Flops Overview

The MC74AC74DTR2G is a dual D-type positive-edge triggered flip-flop from the onsemi 74AC series, housed in a 14-TSSOP surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 160 MHz. The device features asynchronous preset and clear inputs, with complementary outputs capable of sourcing and sinking 24 mA. Typical propagation delay is 14 ns at 5 V, and static current consumption is 4 µA.

Flip Flops Feature Summary

• Dual D-type configuration with positive-edge triggering for synchronized data capture
• Asynchronous preset and clear inputs allowing independent output control
• Complementary outputs providing both non-inverting and inverting signals

Flip Flops Applications

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

Flip Flops Procurement Notes

Verify the complete part number against official documentation, as the suffix 'DTR2' may indicate specific packaging or revision details not fully detailed in general listings. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with high-speed operation up to 160 MHz is required. Ensure the 2 V to 6 V operating range matches your system power rails. Consider the 14-TSSOP package dimensions for PCB layout constraints and verify thermal management needs for the -40°C to +85°C operating temperature range.

Flip Flops Part Context

This device belongs to the MC74AC74 family, which includes variants like MC74AC74DG (SOIC) and MC74ACT74 (TTL-compatible inputs). The AC series offers faster switching speeds compared to standard HC logic, while maintaining CMOS low-power characteristics. The TSSOP package provides a compact footprint suitable for space-constrained designs.

Flip Flops Replacement Considerations

MC74AC74DG serves as a direct pin-compatible alternative in a 14-SOIC package. For TTL-compatible input requirements, consider the MC74ACT74 series. Verify that any substitute maintains the same 24 mA output drive capability and 160 MHz clock frequency specification.
