NL27WZU04DTT1

Overview

The NL27WZU04DTT1 is a dual unbuffered inverter from the NL27WZ series, manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes CMOS logic technology. The device features high-impedance TTL-compatible inputs that reduce current loading on input drivers, while its outputs are designed for balanced sourcing and sinking capabilities. Packaged in a compact TSOP-6 surface-mount configuration, it supports an operating temperature range from -55 °C to +125 °C. Key electrical characteristics include a maximum propagation delay of 11 ns at 15 pF load, with output currents rated at ±32 mA.

Feature Summary

• Dual unbuffered inverter architecture providing two independent logic inversion channels
• High-impedance TTL-compatible inputs to minimize driver current load
• Balanced output drive capability supporting both sourcing and sinking operations
• Wide operating voltage range compatible with 1.65 V to 5.5 V systems

Applications

• General-purpose digital signal inversion in low-voltage logic circuits
• Interface buffering between TTL and LVCMOS logic families
• Signal path conditioning in portable electronic devices
• Automotive electronics requiring extended temperature operation

Procurement Notes

Verify the exact suffix designation, as official documentation typically lists NL27WZU04DTT1G. Confirm RoHS compliance status and lead times directly with onsemi or authorized distributors. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements. Check for end-of-life notices or alternative package options if the specific TSOP-6 variant is discontinued.

Selection Notes

Select this component when unbuffered inversion is required for minimal capacitance loading. The wide voltage range allows compatibility with both 1.8 V and 5 V systems. Consider the TSOP-6 package for space-constrained PCB layouts. Verify input compatibility with driving sources to ensure proper logic level translation across the full temperature range.

Part Context

This part belongs to the NL27WZ family of high-speed CMOS logic devices. The 'U' designation indicates an unbuffered version, distinguishing it from buffered variants like the NL27WZ04. It serves as a cost-effective solution for basic logic inversion tasks where signal integrity does not require buffering. The family is known for low static power consumption and robust noise immunity.

Replacement Considerations

NL27WZ04DTT1G: Buffered dual inverter with similar electrical characteristics but different output structure. NL27WZU04DFT2G: Unbuffered dual inverter in SC-70-6 package. NC7W04: Legacy equivalent with comparable functionality but potentially different performance metrics.
