The TC7SZ17FE(TE85L) is a single non-inverting Schmitt-trigger buffer/driver from Toshiba Semiconductor and Storage. This device features a single non-inverting gate with a Schmitt-trigger input, providing hysteresis to improve noise immunity and signal conditioning. It is designed for low-voltage operation and comes in a small package suitable for space-constrained environments. The TE85L marking refers to the packaging and reel options for automated assembly.

Applications:

• Noise Filtering: Used to clean up noisy signals in digital circuits while maintaining the signal's polarity.
• Pulse Shaping: Converts slow-changing signals into clean, fast pulses without inverting them.
• Hysteresis Control: Provides hysteresis for improved noise immunity in various non-inverting applications.
• Switch Debouncing: Eliminates switch bounce in mechanical switches while preserving the signal's polarity.

Additional Details:

The TC7SZ17FE(TE85L) comes in a surface-mount package (e.g., SOT-23 or similar). The operating temperature range typically spans from -40°C to +85°C. The propagation delay time is typically in the range of nanoseconds. It is compatible with both TTL and CMOS logic levels. The Schmitt-trigger action ensures that the output switches cleanly even with slow or noisy input signals. The TE85L marking is related to the tape and reel specifications for automated assembly. It is beneficial in applications where clean and reliable digital signals are required without inverting the input, especially in noisy environments. The hysteresis voltage is a key parameter that determines the noise immunity of the device. It also provides a driving capability to drive more load as compared to just simple buffer.
