Overview
The MC74LCX244DTEL is a low-voltage CMOS octal buffer featuring 5 V-tolerant inputs and outputs. It operates with a supply voltage range of 2.0 V to 3.6 V. The device provides non-inverting, three-state output control for eight channels. It utilizes advanced silicon gate CMOS technology to achieve high-speed operation while maintaining low power consumption. The component is housed in a 20-pin TSSOP package suitable for surface-mount applications.
Feature Summary
- Provides five-volt tolerant input and output capabilities for mixed-voltage system interfacing
- Features three-state output control to manage bus line sharing and isolation
- Utilizes advanced silicon gate CMOS technology for high-speed performance and low static power
Applications
- Memory module data buffering
- Clock distribution networks
- Bus-oriented architectures requiring level translation
Procurement Notes
Verify the specific suffix DTEL corresponds to the 20-lead Thin Shrink Small Outline Package (TSSOP) configuration. Confirm that the ordering part number includes the RoHS compliance designation if required by your manufacturing standards. Ensure the procurement documentation matches the manufacturer's official datasheet specifications for the LCX logic family.
Selection Notes
Select this component when designing systems that require driving loads between different voltage domains, specifically from lower voltages up to 5 V tolerance. The low voltage operation makes it suitable for portable electronics. Consider the package size constraints and the need for high-speed signal integrity in digital bus applications.
Part Context
This part belongs to the 74LCX series of low-voltage CMOS logic devices manufactured by onsemi. The LCX family is designed to replace older HC/HCT technologies in battery-powered applications due to its wider operating voltage range and improved speed-power product characteristics compared to standard CMOS logic families.
Replacement Considerations
Direct replacements include other manufacturers' equivalents such as the SN74LCX244 or NXP variants. Verify pin compatibility and electrical parameters before substitution. Generic 74LCX244 parts may differ in packaging; ensure the TSSOP form factor matches the PCB footprint.
