TC74LCX14FK(EL,K)

Inverter Gates Overview

The TC74LCX14FK(EL,K) is a low-voltage hex Schmitt inverter manufactured by Toshiba Semiconductor and Storage. It operates within a power supply voltage range of 1.65 V to 3.6 V, with specific data retention support down to 1.5 V. The device features high-speed operation with a maximum propagation delay of 6.5 ns at 3.0 V to 3.6 V. It provides an output current capability of ±24 mA minimum at 3.0 V. Inputs and outputs are tolerant to 5.5 V levels, allowing safe interfacing between 3.3 V logic and 5 V environments. The component includes power-down protection on all pins.

Inverter Gates Feature Summary

• Hex Schmitt trigger configuration for noise immunity
• 5-V tolerant inputs and outputs for mixed-voltage systems
• Power-down protection on all input and output pins

Inverter Gates Applications

• Line receivers for slow input signals
• Low-voltage (3.3 V) system applications
• Interface circuits between 5 V and 3 V systems

Inverter Gates Procurement Notes

Verify the specific package suffix against the datasheet: 'F' denotes JEDEC SOP-14, while 'FK' indicates VSSOP (US). Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as environmental certifications can vary by production batch and region. Ensure the ordering code matches the required physical footprint for PCB layout compatibility.

Inverter Gates Selection Notes

Select this component when hysteresis is required to clean up noisy or slow-rising digital signals. It serves as a direct pin-compatible replacement for standard 74 series inverters like 74HC, 74AC, and 74VHC families. Choose this part over the non-Schmitt TC74LCX04 if signal integrity regarding threshold stability is a priority in the design.

Inverter Gates Part Context

This device belongs to the TC74LCX family of low-voltage CMOS logic ICs from Toshiba. It shares identical pin configurations and functional layouts with other members of the LVC/LCX/Z series, such as the TC74LCX04. The primary distinction lies in the internal input stage, which incorporates Schmitt trigger circuitry rather than standard CMOS thresholds.

Inverter Gates Replacement Considerations

Pin-compatible substitutes include the TC74LCX04 (non-Schmitt), TC74VHC14, and TC74AC14. Verify that the alternative device supports the required 5-V tolerance and operating voltage range before substitution.

Inverter Gates FAQ

What is the difference between the TC74LCX14 and TC74LCX04?

The TC74LCX14 includes Schmitt trigger inputs for hysteresis and noise immunity, whereas the TC74LCX04 has standard CMOS inputs without hysteresis.

Can the TC74LCX14 interface 5 V signals to a 3.3 V system?

Yes, the inputs and outputs are designed to tolerate voltages up to 5.5 V, making them suitable for interfacing 5 V systems with 3.3 V logic.
