The TC7W14F TE12L is a high-speed CMOS Schmitt-trigger inverter manufactured by Toshiba Semiconductor and Storage. It is designed for applications requiring noise immunity and signal conditioning. The Schmitt-trigger input provides hysteresis, which helps to eliminate false triggering caused by noisy or slowly changing input signals. This device is fabricated using silicon gate CMOS technology, enabling high-speed operation and low power consumption.

Applications

• Wave shaping circuits
• Pulse shaping circuits
• Noise suppression

Additional Details

The TC7W14F TE12L operates over a temperature range of -40°C to 85°C. The input and output pins are protected against electrostatic discharge (ESD). The device is available in a TSSOP8 package, which is suitable for surface mounting on printed circuit boards. The hysteresis voltage ensures clean switching transitions even with slow or noisy input signals.

The TE12L designation indicates a specific tape and reel packaging configuration for automated assembly processes. The Schmitt trigger action occurs when the input signal reaches a certain threshold (positive-going threshold voltage, VT+) to switch the output to one state, and a different threshold (negative-going threshold voltage, VT-) to switch the output back. The difference between VT+ and VT- is the hysteresis voltage, which helps to prevent oscillations and false triggering.
