The MM74HC240MTCX is a dual inverting buffer from onsemi's 74HC family, featuring 3-State outputs and two channels. It operates across a wide 2V to 6V supply range, with 7.8mA output current per channel. Housed in a compact 20-TSSOP package, it is ideal for bus-oriented systems, signal buffering, and level-shifting applications in industrial and consumer electronics.
- Wide 2V to 6V Supply Range: Compatible with both 3.3V and 5V systems, simplifying mixed-voltage design.
- 3-State Outputs: Enables bus sharing and prevents data contention in multiplexed architectures.
- High-Speed CMOS Performance: Low propagation delay ensures reliable operation in high-frequency digital circuits.
- Industrial Temperature Range: -40°C to 85°C operation suits harsh environments.
Bus Interfacing in Mixed-Voltage Systems
The 3-State outputs and wide 2V-6V supply range make the MM74HC240MTCX ideal for isolating and buffering data buses between 3.3V and 5V logic sections, preventing bus contention and signal degradation.
Signal Buffering for High-Capacitance Loads
With 7.8mA sink/source capability, this buffer can drive long PCB traces and multiple gate inputs, maintaining signal integrity in high-speed digital designs.
Inverting Logic for Polarity Correction
The inverting function is useful in applications where an inverted version of a control signal is required, such as in enable/disable logic or clock distribution networks.
Level Shifting for Sensor Interfaces
Operating from 2V to 6V, it can shift logic levels between low-voltage sensors (2V) and standard 5V microcontrollers, simplifying interface design.
Industrial Control Input/Output Modules
The -40°C to 85°C temperature range and robust CMOS construction make it suitable for industrial PLCs and control systems requiring reliable signal buffering.
Memory Address/Data Line Driving
In microprocessor systems, the 3-State outputs allow the buffer to be disabled, enabling multiple memory banks to share the same address/data bus without conflict.
