74LCX244MTCX_E4

Overview

The onsemi 74LCX244MTCX_E4 is an octal buffer and line driver belonging to the 74LCX logic family. It features eight non-inverting channels with three-state outputs, housed in a 20-pin TSSOP surface-mount package. The device operates within a supply voltage range of 2.0 V to 3.6 V and supports 5 V-tolerant inputs and outputs. Designed for low-voltage CMOS applications, it provides high-speed signal buffering while maintaining low power consumption.

Feature Summary

• Provides eight independent non-inverting buffer channels for signal routing
• Features three-state outputs to facilitate bus-oriented architectures
• Supports 5 V-tolerant I/O interfaces for mixed-voltage system compatibility
• Operates efficiently within a low voltage range of 2.0 V to 3.6 V

Applications

• Memory module data buffering
• Clock distribution networks
• Consumer electronics signal processing
• Industrial control systems

Procurement Notes

Verify the E4 suffix indicates lead-free compliance per JEDEC standards. Confirm the specific TSSOP-20 package dimensions match your PCB footprint requirements. Ensure input voltage levels remain within the specified tolerance limits to prevent damage. Check for any recent product change notices regarding manufacturing site or material composition updates.

Selection Notes

Select this component when designing low-voltage digital circuits requiring octal buffering capabilities. The 5 V tolerance feature allows direct interfacing between 3.3 V logic domains and legacy 5 V peripherals without additional level shifting components. Consider the TSSOP-20 package for space-constrained surface-mount designs.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from onsemi. The LCX family is optimized for high-speed operation with reduced power dissipation compared to older HC/HCT technologies. The 244 variant specifically denotes an octal buffer configuration with three-state output control, widely used in digital system interconnects.

Replacement Considerations

Compatible substitutes include the MM74LCX244MTCX and MC74LCX244MTCX. Verify pinout compatibility and electrical specifications before substitution. The base model 74LCX244MTCX serves as the primary functional equivalent.
