NL37WZ14USG

Overview

The NL37WZ14USG is a triple inverter from the LCX logic series, featuring Schmitt-trigger inputs for noise immunity. It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes CMOS technology. The device provides balanced output drive capabilities with high-level and low-level output currents specified at 24 mA. Propagation delay is typically 2.0 ns at 3.3 V and 2.4 ns at 5 V. It is housed in an 8-US package (US-8) suitable for surface mount applications.

Feature Summary

• Schmitt-trigger inputs convert slow or noisy signals into clean, defined output transitions.
• Wide operating voltage range supports compatibility with various logic families including LVTTL and LVCMOS.
• High noise margin reduces susceptibility to interference during signal transmission.

Applications

• Signal conditioning for slow input waveforms
• Noise filtering in digital communication lines
• Level translation between different voltage domains

Procurement Notes

Verify the specific suffix USG against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration for your assembly process. Cross-reference the component marking code with official documentation to prevent counterfeit substitution.

Selection Notes

Select this component when input signal integrity is compromised by noise or slow rise times requiring hysteresis. It serves as a direct functional replacement for the NL37WZ04 where Schmitt-trigger action is necessary rather than standard inversion. Consider the 24 mA drive strength for moderate capacitive loads while maintaining low static power consumption.

Part Context

This device belongs to the NL37WZ family of ultra-high-speed CMOS logic circuits. It shares pinout compatibility with the NL37WZ04 but adds Schmitt-trigger functionality. The LCX series is designed for low power dissipation and broad voltage operation, making it suitable for portable and battery-powered electronic systems requiring reliable logic inversion.

Replacement Considerations

NL37WZ04USG offers identical pinout and electrical characteristics except for the absence of Schmitt-trigger inputs on the pins.

FAQ

How does the Schmitt-trigger input improve performance compared to standard inverters?

The Schmitt-trigger input provides hysteresis, which prevents output oscillation caused by noise or slow-rising input signals, ensuring stable logic states.

Is the NL37WZ14USG compatible with 5V TTL logic levels?

Yes, the device is LVTTL compatible and can interface with 5V TTL logic when operated at a 3.3V supply voltage.
