The MM74HC244WM is a high-speed CMOS octal buffer with 3-State outputs from onsemi. Operating from 2V to 6V, it provides 7.8mA output current per channel. The non-inverting buffer maintains signal polarity, while 3-State outputs enable bus sharing. Packaged in a 20-SOIC, it is suitable for microprocessor bus buffering, memory interfacing, and LED driving. Its wide voltage range and temperature tolerance make it versatile for consumer and industrial applications.
- Wide Supply Range (2V-6V): Works with 3.3V and 5V systems, reducing inventory complexity.
- 3-State Outputs: Enable bus multiplexing without external components.
- SOIC-20 Package: Industry-standard footprint for easy PCB layout.
- High-Speed CMOS: Low power consumption with fast switching.
Microprocessor Bus Buffering
Isolate the CPU from heavy bus loads. The 3-State outputs allow multiple peripherals to share the data bus, controlled by enable signals.
Memory Interfacing
Buffer address lines to DRAM or SRAM. The 2V-6V range supports both 3.3V and 5V memory, while 7.8mA output drives trace capacitance.
LED Matrix Drivers
Drive LED arrays with the 7.8mA output current. The non-inverting buffer simplifies firmware, and 3-State outputs allow multiplexing.
Automotive Electronics
Buffer sensor signals in engine control units. The wide temperature range (-40°C to 85°C) covers automotive cabin environments.
Power Supply Sequencing
Buffer power-good signals in multi-rail systems. The 3-State outputs allow OR-ing of signals without contention.
Consumer Electronics
Interface between logic ICs in TVs, set-top boxes, and gaming consoles. The SOIC package is ideal for high-volume manufacturing.
