MC74ACT374N

Flip Flops Overview

The MC74ACT374N is an obsolete octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features positive-edge triggering and non-inverting outputs with three-state capability. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 155 MHz. Propagation delay is specified at 9.5ns under 5V supply with 50pF load. It utilizes a 20-pin DIP package for through-hole mounting and functions across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs allowing direct bus connection without external buffers
• Positive-edge triggered data capture synchronized with clock transitions
• Non-inverting output polarity maintaining input signal logic state

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage elements in digital systems
• Shift register configurations for data movement
• Buffer memory interfaces for microprocessor systems

Flip Flops Procurement Notes

This component is officially discontinued and no longer manufactured by onsemi. Procurement must rely on surplus distributors or secondary markets. Verify authenticity carefully as obsolete parts carry higher counterfeit risk. Confirm package integrity and pin condition before integration. Cross-reference with parameter-equivalent alternatives from other manufacturers if new production is required.

Flip Flops Selection Notes

Select this part only for legacy system maintenance or repair where original specifications are mandatory. The 20-PDIP package requires through-hole PCB technology. Consider voltage compatibility as the 2V lower limit differs from standard 5V-only logic families. Evaluate replacement options if new designs allow, as active equivalents offer better availability and updated compliance standards.

Flip Flops Part Context

The MC74ACT374N belongs to the broader 74AC family of high-speed CMOS logic devices. It serves as the through-hole variant of the surface-mount MC74ACT374DWG. The 'N' suffix denotes the plastic dual in-line package format. This specific part number represents an older generation product that has been superseded by newer manufacturing runs or alternative packaging styles within the same logical family.
