74LCX2244MTCX

Overview

The Fairchild Semiconductor 74LCX2244MTCX is a low voltage buffer and line driver featuring eight non-inverting buffers with three-state outputs. It operates within a supply voltage range of 2.3V to 3.6V and includes five-volt tolerant inputs and outputs. The device utilizes advanced CMOS technology for high-speed operation while maintaining low power dissipation. It is housed in a 20-TSSOP package with a width of 4.40mm. Key electrical specifications include a maximum propagation delay of 6.5ns at 3.3V and an output drive capability of ±24mA at 3.0V.

Feature Summary

• Provides five-volt tolerant inputs and outputs for safe interfacing between different voltage domains
• Features three-state outputs to support bus-oriented transmission and reception applications
• Implements patented noise and EMI reduction circuitry for improved signal integrity
• Supports live insertion and withdrawal due to power-down high impedance state

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor operations are now part of onsemi. Confirm the package type matches the required 20-TSSOP configuration with a 4.40mm width. Ensure the component meets the specified operating temperature range of -40°C to 85°C. Check for RoHS compliance and lead-free status if required by your assembly process. Validate that the datasheet revision aligns with your design requirements.

Selection Notes

Select this component when interfacing low voltage logic with five-volt environments is required. It is suitable for designs needing high-speed buffering with minimal power consumption. Consider the three-state output capability for multiplexed bus systems. Ensure the supply voltage stays within the 2.3V to 3.6V range for optimal performance. Verify that the package dimensions fit the available PCB space constraints.

Part Context

This device belongs to the LCX series of low voltage CMOS logic components. It is functionally similar to other buffer drivers like the 74LCX244 but offers specific package options. The LCX series is designed for applications requiring fast switching speeds and low static power dissipation. It serves as a bridge between modern low voltage digital systems and legacy five-volt interfaces.

Replacement Considerations
