TC74HC14AFELF

Inverter Gates Overview

The TC74HC14AFELF is a hex Schmitt inverter from Toshiba's HC series, fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 to 6.0 V and functions across temperatures from -40°C to 85°C. The device features balanced propagation delays with a typical tpd of 11 ns at 5 V. It provides an output drive capability equivalent to 10 LSTTL loads, with symmetrical output impedance of 4 mA minimum. Quiescent current is limited to 1.0 µA maximum at 25°C.

Inverter Gates Feature Summary

• Schmitt trigger inputs provide hysteresis for noise immunity and stable reception of slow input signals
• High-speed operation comparable to LSTTL while maintaining low CMOS power dissipation
• Symmetrical output impedance ensures balanced propagation delays
• Input protection circuits guard against static discharge or transient excess voltage

Inverter Gates Applications

• Line receivers for slow input signals
• Signal conditioning applications requiring noise filtering
• General-purpose logic inversion in digital systems

Inverter Gates Procurement Notes

Verify the specific ordering suffix EL,F corresponds to the SOP-14 tape and reel packaging configuration as indicated by distributor listings. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure design reviews account for the absolute maximum ratings and derating requirements specified in the reliability handbook.

Inverter Gates Selection Notes

Select this component when Schmitt trigger functionality is required for signal integrity rather than standard logic inversion. The HC series offers speed similar to LSTTL with lower power consumption. Verify that the 2.0 V to 6.0 V operating range aligns with the system supply voltage. Consider the SOP-14 package dimensions if space constraints exist compared to the DIP variant.

Inverter Gates Part Context

This part belongs to the TC74HC14AP/AF family of hex Schmitt inverters. The AF designation typically indicates the surface-mount SOP-14 package, while AP denotes the through-hole DIP-14 package. The EL,F suffix specifies the specific tape and reel packaging format used for automated assembly processes.

Inverter Gates Replacement Considerations

The datasheet notes pin and function compatibility with the 74LS14. However, electrical characteristics such as voltage levels and drive strength differ between HC CMOS and LS TTL technologies. Verify interface compatibility before substitution.
