74LCX241MTC

Overview

The onsemi 74LCX241MTC is an octal buffer and line driver fabricated with advanced CMOS technology. It operates at low voltage levels of 2.5V or 3.3V, featuring 5V tolerant inputs and outputs for interfacing with 5V signal environments. The device provides high-speed operation with a maximum propagation delay of 6.5 ns at VCC = 3.3V. It includes power-down high-impedance states and supports live insertion/withdrawal capabilities.

Feature Summary

• Features 5V tolerant inputs and outputs for seamless interfacing with 5V signal environments while operating at lower supply voltages.
• Incorporates patented noise and EMI reduction circuitry to enhance signal integrity during high-speed switching operations.
• Supports live insertion and withdrawal through power-down high-impedance input and output states.

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Procurement Notes

Verify the specific package variant (TSSOP, SOIC, SSOP) required for your design, as the base model number corresponds to multiple physical packages. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding manufacturing site changes or material updates before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal buffering with mixed-voltage interfaces. Ensure the operating temperature range meets application requirements. Consider the 5V tolerance feature if interfacing directly with legacy 5V logic without level shifters. Verify that the drive current capabilities meet the load requirements of the destination circuits.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. It serves as a non-inverting octal buffer and line driver. The MTC suffix specifically denotes the 20-Lead Thin Shrink Small Outline Package (TSSOP). It is functionally similar to other octal buffers in the series but distinguished by its specific package footprint and pinout configuration.

Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering 8-bit bus transceivers with 5V tolerance. Ensure replacement components match the TSSOP-20 package dimensions and electrical characteristics, particularly propagation delay and supply voltage ranges.
