MC74AC377DWR2

Flip Flops Overview

The MC74AC377DWR2G is an octal D-type flip-flop with clock enable, manufactured by onsemi in the 74AC logic series. It features a single-ended non-inverting output configuration housed in a 20-SOIC surface-mount package. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 140 MHz. Key electrical parameters include a propagation delay of 13 ns, high-level output current of -24 mA, and low-level output current of 24 mA. Static current (Iq) is specified at 8 µA, with an input capacitance of 4.5 pF. Operating temperature ranges from -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with integrated clock enable functionality for data control
• Single-ended non-inverting outputs capable of sourcing and sinking 24 mA drive current
• CMOS construction ensuring low static power consumption and high noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• General-purpose storage elements in microprocessor-based designs

Flip Flops Procurement Notes

Verify the complete part number includes the suffix 'G' indicating RoHS compliance and halogen-free status. Confirm the package designation matches SOIC-20 dimensions. Ensure moisture sensitivity level (MSL 3) handling procedures are followed during assembly. Cross-reference the manufacturer's latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to final design approval.

Flip Flops Selection Notes

Select this component when an octal storage element with clock enable is required within the 74AC family. Compare against the MC74ACT377DWR2G if TTL-compatible inputs at 5 V are necessary, as the AC variant offers broader voltage flexibility. Evaluate the 13 ns propagation delay against system timing requirements. Consider the 20-SOIC package constraints for PCB layout and thermal management in dense assemblies.

Flip Flops Part Context

This device belongs to the MC74AC377 series of octal D-type flip-flops. It is functionally related to other 74AC logic components but distinguished by its specific eight-bit parallel storage capability. The DWR2G suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.
