MM74HC74AMTCX

Flip Flops Overview

The MM74HC74AMTCX is a dual D-type flip-flop from the onsemi HC logic family, housed in a 14-TSSOP surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features independent data, preset, clear, and clock inputs with complementary Q and Q outputs. Key electrical parameters include a propagation delay of 110 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It utilizes advanced silicon-gate CMOS technology for low power consumption and high noise immunity.

Flip Flops Procurement Notes

Verify the specific ordering suffix 'MTCX' corresponds to the TSSOP-14 package and reel/cut-tape packaging options as listed in official distributor catalogs. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements against your assembly process specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop solution is required with low power consumption and compatibility with LS-TTL loads. Ensure the design accommodates the 2V to 6V supply range and that the TSSOP-14 footprint fits the PCB layout constraints. Consider the 110 ns propagation delay for timing-critical applications.

Flip Flops Part Context

This part belongs to the MM74HC74A series, which represents dual D-type flip-flops within the broader 74HC logic family. The HC series is characterized by wide operating voltage ranges and high-speed performance comparable to older LS-TTL standards while maintaining CMOS low-power advantages. The 'A' variant often denotes specific manufacturing revisions or enhanced specifications within the product line.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include MC74HC74ADTR2G and MM74HC74AMX. Verify pinout compatibility and electrical parameter equivalence before substitution.
