Overview
The onsemi 74LCX240MTCX is an inverting octal buffer and line driver fabricated with advanced CMOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V, featuring 5 V tolerant inputs and outputs for interfacing with 5 V signal environments. The device provides three-state outputs controlled by OE1 and OE2 inputs. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 3.3 V, quiescent current of 10 µA max, and output drive capability of ±24 mA at 3.0 V. It supports live insertion/withdrawal and includes proprietary noise/EMI reduction circuitry.
Feature Summary
- Provides five-volt tolerant inputs and outputs for low voltage applications
- Supports live insertion and withdrawal via power-down high impedance state
- Implements proprietary noise and EMI reduction circuitry
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmitters or receivers
Procurement Notes
Verify the specific ordering suffix 'MTCX' corresponds to the TSSOP-20 package configuration as documented in the official datasheet. Confirm RoHS compliance status and lead-free packaging details directly from the manufacturer's ordering information section before procurement.
Selection Notes
Select this component when designing systems requiring inverting buffering between different voltage domains, specifically interfacing low voltage logic with 5 V signals. Ensure the application utilizes the recommended operating temperature range and respects the absolute maximum ratings for input and output voltages during power-up and power-down cycles.
Part Context
This part belongs to the LCX family of low voltage logic devices manufactured by onsemi. It serves as the inverting counterpart to the non-inverting 74LCX244. The MTCX suffix indicates the specific surface-mount TSSOP-20 package variant available in tape and reel shipping configurations.
Replacement Considerations
The 74LCX244MTCX is a similar non-inverting buffer from the same manufacturer. Verify functional compatibility regarding inversion polarity and pinout alignment before substituting.
