74AC377MTC

Overview

The onsemi 74AC377MTC is an octal D-type flip-flop featuring clock enable functionality, belonging to the 74AC logic series. It operates within a supply voltage range of 2 V to 6 V and supports single-ended inputs and outputs with non-inverting polarity. The device provides high drive capability with output currents of ±24 mA and exhibits a propagation delay of 13 ns. Designed for surface-mount applications, it is housed in a TSSOP-20 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering and dedicated clock enable control.
• Delivers robust load driving through high-current CMOS outputs capable of sourcing and sinking 24 mA.
• Ensures signal integrity via low input capacitance and fast propagation delays characteristic of the AC logic family.

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the ordering part number matches the exact pinout and electrical characteristics defined by the manufacturer for the intended application environment.

Selection Notes

Select this component when an octal storage solution with clock enable is required in a compact surface-mount form factor. The 74AC series offers superior speed compared to standard 74LS devices while maintaining CMOS power efficiency. Verify that the system voltage falls within the 2 V to 6 V operating range and that the thermal management supports the specified industrial temperature limits.

Part Context

This device is part of the broader 74AC377 family, which includes variants such as MC74AC377DTG (TSSOP) and MC74AC377DWR2G (SOIC). While functional specifications remain consistent across the series, packaging and reel quantities differ. The MTC suffix specifically denotes the TSSOP-20 package configuration used for space-constrained printed circuit board designs.
