TC74HC14APF

Inverter Gates Overview

The TC74HC14APF is a hex Schmitt inverter manufactured by Toshiba Semiconductor and Storage using silicon gate C2MOS technology. It features six independent inverters with Schmitt trigger inputs providing hysteresis for noise immunity. The device operates within a supply voltage range of 2 V to 6 V, drawing a maximum quiescent current of 1 µA at 25°C. Typical propagation delay is 11 ns at 5 V, with a maximum of 21 ns under specified conditions. Output drive capability supports up to 10 LSTTL loads with symmetrical output impedance.

Inverter Gates Feature Summary

• Schmitt trigger input function provides hysteresis for receiving slow input signals
• High speed operation comparable to equivalent LSTTL while maintaining low power dissipation
• Symmetrical output impedance ensures balanced propagation delays
• Integrated protection circuits against static discharge or transient excess voltage on all inputs

Inverter Gates Applications

• Line receivers for slow input signals
• General electronics applications including computers and office equipment
• Industrial robots and measuring equipment
• Home electronics appliances

Inverter Gates Procurement Notes

Verify the specific package type matches the required application, as the TC74HC14A series includes DIP, SOP, and SOL options. Confirm RoHS3 compliance status through official Toshiba documentation prior to procurement. Ensure design accounts for absolute maximum ratings, particularly regarding power dissipation derating factors above 65°C. Validate that operating temperature ranges align with system requirements.

Inverter Gates Selection Notes

Select this component when high noise immunity is required due to its Schmitt trigger characteristics. It serves as a functional replacement for 74LS14 devices while offering lower power consumption typical of CMOS logic. Consider the wide operating voltage range suitable for various digital systems. Verify pin compatibility if substituting into existing designs originally utilizing LS-TTL families.
