74AC74MTC

Overview

The Fairchild Semiconductor 74AC74MTC is a dual D-type positive edge-triggered flip-flop housed in a 14-lead Thin Shrink Small Outline Package (TSSOP). It features asynchronous Set and Clear inputs, complementary Q and Q outputs, and TTL-compatible inputs. The device supports output source/sink currents of 24 mA with reduced quiescent current. Operating voltage ranges from 2.0 V to 6.0 V, with an operating temperature range of -40 °C to 85 °C.

Feature Summary

• Dual D-type positive edge-triggered flip-flops with asynchronous Set and Clear functions
• Complementary Q and Q outputs for versatile logic interfacing
• High drive capability with 24 mA output source and sink currents

Applications

• Parallel data storage registers
• Shift register construction
• Frequency division circuits

Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor's logic portfolio was acquired by onsemi. Confirm that the 74AC74MTC designation corresponds to the correct package type and pinout configuration required for your design. Ensure compliance with RoHS standards if applicable to your manufacturing process.

Selection Notes

Select this component when a compact dual flip-flop solution is needed with high-speed performance and strong drive capabilities. The TSSOP package offers space efficiency for surface-mount designs. Consider the ACT variant if strict TTL input compatibility at lower voltages is required, though the AC series provides broader voltage flexibility.

Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic circuits. The MTC suffix specifically denotes the 14-lead TSSOP package format, distinguishing it from SOIC or DIP variants within the same logical function family.

Replacement Considerations

Direct substitutes include 74ACT74MTC for enhanced TTL compatibility and 74HC74MTC for standard HC speed. Cross-manufacturer equivalents from STMicroelectronics or NXP are available but require verification of pinout and electrical parameter alignment.
