Key Features

• Logic Type: Non-Inverting Buffer
• Input/Output: Schmitt Trigger Input / Push-Pull Output
• High/Low Drive: 32mA sink/source capability
• Voltage Range: 1.65V to 5.5V operation
• Temperature Range: -55°C to +125°C (TA)
• Package: SC-88/SC70-6/SOT-363 (Surface Mount)

Technical Details

This dual-channel buffer features two independent 1-bit elements with Schmitt trigger inputs that provide hysteresis for noise rejection. The push-pull output stage delivers symmetrical 32mA drive current for both high and low states. Housed in an ultra-compact 6-pin SOT-363 package, it operates across industrial (-40°C to +85°C) and extended (-55°C to +125°C) temperature ranges. The wide supply voltage compatibility supports mixed-voltage system designs.

Typical Applications

• Signal conditioning in IoT sensors
• Level shifting in portable electronics
• Noise filtering in industrial controllers
• Clock signal buffering
• Bus interface protection

About Logic Buffers

Logic buffers serve as fundamental signal integrity components in digital circuits, amplifying current while maintaining voltage levels. They prevent signal degradation across long traces or when driving multiple loads, acting as impedance-matching interfaces between different circuit sections. Non-inverting types like the NL27WZ17 preserve signal polarity while improving noise margins.

Schmitt trigger variants add hysteresis to “clean” noisy signals by establishing distinct input voltage thresholds for low-to-high and high-to-low transitions. This feature makes them essential in environments with electrical interference, such as motor control systems, automotive electronics, and industrial automation where signal reliability directly impacts system safety.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® packaging for automated assembly. All options include moisture-sensitive packaging compliant with IPC/JEDEC J-STD-033 standards.

Frequently Asked Questions

Q: What advantage does Schmitt trigger input provide?
A: It prevents output oscillation with slow/noisy signals by requiring 0.9V minimum hysteresis between rising/falling thresholds.

Q: Can this buffer interface with 3.3V and 5V systems?
A: Yes, its 1.65-5.5V supply range allows bidirectional level translation between various logic families.

Q: Is this IC suitable for automotive applications?
A: While not AEC-Q100 certified, its -55°C to +125°C range supports industrial and extended-temperature designs.

Q: What is the typical propagation delay?
A: 8.5ns at 5V supply (refer to PCX-hosted datasheet for full specifications).

Q: How does push-pull output differ from open-drain?
A: Push-pull actively drives both high and low states without external pull-up resistors, enabling faster switching.

Q: Can I use this for I2C bus buffering?
A: Not recommended – use bidirectional buffers specifically designed for I2C voltage translation.
