Overview
The MC74LCX240M is an octal bus buffer and line driver manufactured by onsemi, belonging to the 74LCX logic series. It features inverting outputs with three-state capability, allowing multiple drivers to share a bus without contention. The device operates within a supply voltage range of 2.0 V to 3.6 V, ensuring compatibility with low-voltage digital systems. It provides balanced propagation delays and high noise immunity, making it suitable for memory address buffering and general-purpose data transmission applications.
Feature Summary
- Octal configuration providing eight independent inverting buffers with three-state outputs
- Three-state design enables direct connection to organized data buses
- Low power dissipation characteristics inherent to CMOS technology
- High noise immunity with stable output performance
Applications
- Memory address register buffering
- Clock driver circuits
- Bus-oriented architectures
- Telecommunications equipment signal routing
Procurement Notes
Verify the specific suffix 'M' against official datasheets to confirm package type and tape/reel specifications. Ensure the ordered part matches the required operating temperature range and voltage levels. Confirm RoHS compliance status and check for any specific ordering restrictions or minimum purchase requirements defined by the manufacturer.
Selection Notes
Select this component when an octal inverting buffer with three-state control is required for low-voltage systems. It is appropriate for designs needing interface between 3.3V logic domains and bus structures. Consider the propagation delay and output drive current capabilities relative to load capacitance. Verify pinout compatibility if replacing existing circuitry.
Part Context
This component is part of the 74LCX family, which represents low-voltage CMOS logic optimized for 3.3V operation. The LCX series offers performance comparable to faster logic families while maintaining lower power consumption. It serves as a standard solution for buffering and driving loads in portable and battery-operated electronic devices requiring efficient power management.
Replacement Considerations
Check for equivalents such as MC74LCX240DWR2G or other manufacturers' 74LCX240 variants. Ensure functional compatibility regarding voltage ranges, pin configurations, and electrical characteristics before substitution.
