The MC74HC244ADTR2G from onsemi is an octal buffer/line driver designed for high-speed CMOS systems. It features non-inverting outputs with 3-State control, making it ideal for bus interfacing. Operating from 2V to 6V, it provides 7.8mA source and sink current, compatible with TTL and CMOS logic levels. The 20-pin TSSOP package is compact for space-limited designs. Its wide temperature range (-55°C to 125°C) suits automotive and industrial environments. Typical applications include memory buffering, GPIO expansion, and signal conditioning.
- Wide Supply Range (2V-6V): Works with 3.3V, 5V, and even 6V systems, providing design flexibility.
- Extended Temperature Range (-55°C to 125°C): Suitable for extreme automotive and military applications.
- Low Power CMOS: Consumes minimal quiescent current, ideal for battery-powered devices.
- 3-State Outputs: Allows multiple buffers to share a common bus without interference.
Microcontroller GPIO Expansion
The MC74HC244ADTR2G buffers output signals from a 5V microcontroller to drive multiple LEDs or relays. Its 7.8mA source/sink capability is sufficient for standard indicator LEDs without additional transistors.
Memory Address Line Buffering
In retro-computing or embedded systems, this buffer isolates the CPU address bus from multiple memory chips. The 3-State outputs allow the CPU to release the bus for DMA operations.
Sensor Signal Conditioning
For industrial sensors with 5V outputs, this buffer provides impedance isolation and signal cleaning before feeding into an ADC. The wide 2V-6V range accommodates various sensor supply voltages.
Automotive Body Electronics
With a temperature range of -55°C to 125°C, this device is ideal for under-hood automotive applications, buffering signals from engine control sensors to the ECU.
Test Fixture Signal Distribution
In automated test equipment, the buffer distributes test signals to multiple device-under-test pins simultaneously, ensuring consistent drive strength across all channels.
Battery-Powered Portable Devices
The 74HC family's low power consumption makes this buffer suitable for battery-operated instruments, where it buffers data lines between a low-power MCU and peripheral modules.
