The MC74HC244ADTG is a high-speed CMOS octal buffer with 3-State outputs, designed for bus-oriented systems. Operating from 2V to 6V, it provides 7.8mA output current per channel. The non-inverting buffer preserves signal polarity, while the 3-State outputs enable bus sharing. Housed in a compact 20-TSSOP package, it is ideal for memory interfacing, industrial controls, and general logic buffering. Its wide temperature range supports automotive and industrial applications.
- Wide 2V to 6V Supply Range: Compatible with 3.3V and 5V systems, simplifying mixed-voltage design.
- 3-State Outputs: Enable bus multiplexing without external isolation components.
- Extended Temperature Range (-55°C to 125°C): Suitable for automotive and industrial environments.
- High-Speed CMOS: Low propagation delay for high-frequency signal buffering.
Bus Line Driving
Use the MC74HC244ADTG to buffer address or data lines in microprocessor systems. The 3-State outputs allow multiple devices to share the same bus without contention, controlled by output enable pins.
Memory Address Buffering
In SRAM or Flash memory interfaces, this buffer isolates the CPU from capacitive loads. The 2V-6V range supports both 3.3V and 5V memory systems, improving signal integrity over long traces.
LED Display Multiplexing
Drive multiple LED segments with the 7.8mA output current. The non-inverting buffer maintains logic polarity, simplifying firmware design for multiplexed displays.
Industrial Sensor Interfacing
Buffer signals from industrial sensors (encoders, proximity switches) to PLC inputs. The wide temperature range (-55°C to 125°C) ensures reliable operation in harsh environments.
Level Shifting for Mixed-Voltage Systems
With 2V-6V supply, it can interface 3.3V logic to 5V logic. The 3-State outputs prevent bus conflicts when switching between voltage domains.
Clock Distribution
Buffer clock signals to multiple loads. The high-speed CMOS technology provides low propagation delay, maintaining timing accuracy across fan-out.
