MM74HCT05MTC

Inverter Gates Overview

The MM74HCT05MTC is a hex inverter integrated circuit manufactured by onsemi, belonging to the HCT logic series. It features six independent inverters with open-drain outputs housed in a 14-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of 28 ns at 5 V, low static current consumption, and high noise immunity compatible with TTL logic levels.

Inverter Gates Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status via official datasheets before integration. Check for obsolescence notices since this part may be discontinued. Ensure ESD protection measures are implemented during handling due to CMOS sensitivity. Validate package marking against official specifications to avoid substitution errors.

Inverter Gates Selection Notes

Select this component when hex inversion with open-drain outputs is required in HCT-compatible designs. Consider alternatives if push-pull outputs or higher drive currents are needed. Evaluate thermal dissipation requirements given the TSSOP package limitations. Compare propagation delays against system timing constraints to ensure adequate performance margins for target frequencies.

Inverter Gates Part Context

This component belongs to onsemi's MM74HCT series of high-speed CMOS logic devices. The series provides industry-standard pinouts and functionality compatible with other manufacturers' 74HCT parts. The MM74HCT05 variant specifically offers hex inverters, distinguishing it from NAND, NOR, or buffer variants within the same family. It represents a cost-effective solution for basic logic inversion tasks in consumer and industrial electronics.

Inverter Gates Replacement Considerations

Direct substitutes include SN74HCT05N (Texas Instruments) and MC74HCT05ADTR2G (onsemi). Verify pinout compatibility and electrical parameters before substitution. Ensure replacement parts meet the same voltage and temperature specifications. Check for any functional differences in output drive capability or switching speed.
