TC7W14FU,LF

Inverter Gates Overview

The TC7W14FU,LF is a single-channel Schmitt Inverter from Toshiba's L-MOS Logic series. It utilizes silicon gate C2MOS technology to achieve high-speed operation comparable to equivalent LSTTL while maintaining low power dissipation. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include a typical propagation delay of 11 ns at 5 V, a maximum quiescent current of 1 µA, and symmetrical output impedance with minimum drive currents of 4 mA for both high and low states.

Inverter Gates Feature Summary

• Integrates Schmitt trigger functionality with 25% VCC hysteresis to effectively receive slow input signals.
• Provides high noise immunity through defined threshold voltages across the operating voltage range.
• Includes protection circuits on all inputs against static discharge or transient excess voltage.

Inverter Gates Applications

• Line receivers for processing slow input signals
• Signal conditioning in digital logic circuits
• Noise filtering applications requiring hysteresis

Inverter Gates Procurement Notes

Verify the specific package variant (SSOP-8) and suffix (LF) during procurement to ensure compliance with environmental standards. Confirm that the ordering information matches the required pin configuration and function, as these are identical to the TC7WU04. Ensure design reliability by reviewing the Toshiba Semiconductor Reliability Handbook regarding derating concepts and handling precautions.

Inverter Gates Selection Notes

Select this component when a single Schmitt Inverter is required with LSTTL-compatible speed and drive capability. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider the low power dissipation characteristics if energy efficiency is a priority alongside high-speed performance. Verify that the input signal characteristics align with the specified hysteresis voltage requirements.

Inverter Gates Part Context

The TC7W14FU,LF belongs to the TC7W14 series of high-speed C2MOS Schmitt Inverters. It shares pin configuration and function with the TC7WU04 but distinguishes itself through the addition of Schmitt trigger inputs. This series is designed to bridge the gap between low-power CMOS and high-speed TTL logic families.

Inverter Gates Replacement Considerations

The TC7W14FU/FK shares identical pin configuration and function with the TC7W14FU,LF. Substitution should be verified based on package type (SSOP-8) and environmental compliance requirements associated with the specific suffix.
