The MC74LCX244ADTR2G from onsemi is a dual non-inverting buffer with 3-state outputs, designed for low-voltage applications from 1.65V to 3.6V. It provides 24mA of output current per channel, ensuring robust drive for bus lines and capacitive loads. The 3-state outputs allow multiple devices to share a common bus safely. Housed in a 20-TSSOP package, this buffer is ideal for space-efficient designs in portable electronics, networking, and industrial control systems.
- Low-Voltage Operation (1.65V–3.6V): Compatible with 1.8V, 2.5V, and 3.3V systems, reducing power consumption.
- 3-State Outputs: Facilitates bus sharing and isolation, improving system flexibility.
- 24mA Drive Capability: Ensures reliable signal transmission over moderate trace lengths.
- Wide Temperature Range (-40°C to 125°C): Suitable for harsh automotive and industrial environments.
3.3V to 1.8V Level Shifting
The MC74LCX244A can translate 3.3V signals down to 1.8V logic, enabling communication between modern microcontrollers and legacy peripherals.
Memory Bus Buffering
With 3-state outputs, it can buffer data/address lines in low-voltage memory systems, preventing bus contention during read/write cycles.
FPGA Configuration
Buffering configuration signals from a flash memory to an FPGA at 1.8V or 2.5V ensures reliable programming in low-power designs.
Portable Medical Devices
Its low-voltage operation and 24mA drive make it suitable for battery-powered diagnostic equipment requiring clean signal distribution.
Networking Equipment
In routers and switches, it buffers control signals between ASICs and PHY chips operating at different low voltages.
Industrial Sensors
Isolating sensor outputs from a 3.3V PLC input module protects the controller from noise and voltage spikes.
