74LCXH245MTC

Overview

The Fairchild Semiconductor 74LCXH245MTC is an octal bidirectional bus transceiver featuring three-state outputs. It operates within a supply voltage range of 2.3V to 3.6V and supports live insertion and extraction. The device incorporates patented noise/EMI reduction circuitry and provides high drive capability with outputs sourcing and sinking up to 24mA at VCC = 3.0V. It is housed in a 20-pin TSSOP package.

Feature Summary

• Supports live insertion and extraction without bus loading glitches
• Integrates patented noise and EMI reduction circuitry
• Provides high drive capability with 24mA output current

Applications

• Bus-oriented data transmission systems
• Low voltage memory interface circuits
• Communication control signal routing

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor's logic products are now manufactured by onsemi. Confirm RoHS compliance status and lead-free packaging details directly with the supplier. Ensure the component matches the exact 20-TSSOP physical dimensions and pinout specifications required for your PCB layout before finalizing procurement.

Selection Notes

Select this component when designing low-voltage systems requiring robust bidirectional data transfer between 3.3V and 2.5V domains. It is suitable for applications demanding high noise immunity and glitch-free operation during hot-swapping scenarios. Verify that the 24mA drive strength meets the load requirements of the connected bus lines.

Part Context

This part belongs to the 74LCXH series of low-voltage CMOS logic devices. It serves as a standard solution for interfacing different voltage levels in digital systems while maintaining signal integrity through advanced noise suppression techniques.

Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering the same LCX family specifications. Ensure any substitute maintains the 20-TSSOP footprint and identical electrical characteristics for seamless integration.
