CD74ACT14E

Inverter Gates Overview

The CD74ACT14E is a hex Schmitt-triggered inverter manufactured by Texas Instruments, belonging to the 74ACT logic family. It integrates six independent inverters within a single 14-pin PDIP package designed for through-hole mounting. The device operates on a supply voltage range of 4.5V to 5.5V and supports an extended industrial temperature range from -55°C to +125°C. Key electrical characteristics include a maximum propagation delay of 57ns at specified load conditions, with output drive capabilities of 4mA for low-level current and -4mA for high-level current.

Inverter Gates Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure that the procurement source provides valid traceability data. Confirm that the component meets the required operating temperature range and packaging standards before integration into production designs.

Inverter Gates Selection Notes

Select this component when designing circuits requiring robust noise immunity and clean digital transitions. The Schmitt-trigger inputs are essential for applications where input signals may exhibit significant ringing or slow edge rates. Verify that the system power supply remains within the 4.5V to 5.5V operational limits to ensure correct logic threshold behavior and output drive strength.

Inverter Gates Part Context

This component belongs to the 74ACT series of high-speed CMOS logic devices. The ACT series offers performance comparable to standard TTL logic while maintaining the low power consumption advantages of CMOS technology. The inclusion of Schmitt triggers distinguishes this variant from standard inverters, providing enhanced stability in electrically noisy environments common in industrial control systems.

Inverter Gates Replacement Considerations

Compatible substitutes include the CD74HC14E for HC-series applications and the CD74HCT14E for direct TTL-compatible replacements. Verify that alternative packages maintain identical pin configurations and that the substitute components meet the same voltage and temperature requirements.
