MC74LCX244MNTWG

Overview

The MC74LCX244MNTWG is an octal buffer and line driver from the 74LCX logic family, manufactured by onsemi. It features eight non-inverting channels with three-state outputs in a 20-pin TSSOP surface-mount package. The device operates within a supply voltage range of 1.65V to 3.6V. Key electrical specifications include a maximum propagation delay of 10.3ns, output drive currents of ±24mA, and a low static current of 10μA. It supports operation temperatures from -40°C to +125°C and provides 5V tolerance on inputs and outputs.

Feature Summary

• Provides five-volt tolerant input and output interfaces for mixed-voltage system compatibility
• Features three-state outputs to facilitate bus-oriented architectures and signal isolation
• Supports hot-swapping operations without causing system interference during power transitions

Applications

• Memory address driving applications requiring high impedance states
• Bus-oriented transceiver circuits in consumer electronics
• Clock buffering and distribution in low-voltage digital systems

Procurement Notes

Verify the specific suffix MNTWG against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the exact pinout and electrical characteristics required for your design. Cross-reference with official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require interface between 1.8V or 3.3V logic domains and 5V tolerant peripherals. The wide operating temperature range makes it suitable for industrial environments. Consider the TSSOP package size for space-constrained PCB layouts while ensuring adequate thermal management for continuous operation at elevated temperatures.

Part Context

This component belongs to the MC74LCX244A series of low-voltage CMOS octal buffers. It is part of onsemi's broader portfolio of high-performance logic devices designed for portable and battery-powered applications. The LCX family offers improved speed and lower power consumption compared to older CMOS technologies, making it a standard choice for modern digital interface designs.

Replacement Considerations
