The SN74HC244APW from Texas Instruments is a dual 4-bit non-inverting buffer designed for 2V to 6V operation. It provides 8 channels of buffering with 7.8mA output drive and 3-State outputs for bus-oriented applications. The 74HC family offers high-speed CMOS performance with wide voltage flexibility. The 20-TSSOP package is ideal for space-constrained designs in consumer, industrial, and portable electronics.
- Wide Supply Range (2V-6V): Compatible with 3.3V and 5V systems, simplifying design.
- Low Power Consumption: CMOS technology minimizes static power dissipation.
- 3-State Outputs: Enables bus sharing and prevents data collisions.
- Compact TSSOP Package: Saves PCB space in high-density designs.
- Non-Inverting Buffer: Preserves signal integrity without inversion.
Wide-Voltage Bus Interfacing
Interface between 3.3V and 5V logic systems. The 2V to 6V supply range allows operation in mixed-voltage environments.
Microcontroller I/O Expansion
Buffer multiple GPIO pins from a microcontroller. The 3-State outputs prevent bus contention when multiple devices share lines.
Battery-Powered Devices
Operate at low voltages (2V-3.3V) to reduce power consumption. The 74HC family's CMOS design minimizes static power.
Industrial Control Systems
Drive control signals in factory automation. The wide temperature range (-40°C to 85°C) ensures reliability.
Consumer Electronics
Buffer data lines in TVs, set-top boxes, and gaming consoles. The compact TSSOP package saves board space.
Sensor Signal Conditioning
Buffer analog sensor outputs to digital logic. The non-inverting function preserves signal polarity.
