Pinout

The 74LVC244AD is an octal buffer/line driver with 3-state outputs, commonly used in digital circuits to manage signal integrity and drive capacity. It features 20 pins in its standard package. The pin configuration includes:
- VCC (Pin 20): Positive power supply.
- GND (Pin 10): Ground.
- A0 to A7 (Pins 2, 4, 6, 8, 11, 13, 15, 17): Data inputs.
- Y0 to Y7 (Pins 3, 5, 7, 9, 12, 14, 16, 18): Data outputs.
- OE1 and OE2 (Pins 1 and 19): Output enable inputs (active low).
The device operates as two separate 4-bit buffers or drivers, with each group controlled by its own output enable pin. When the output enable pin is low, the corresponding outputs are enabled; when high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit. This functionality allows for easy management of data flow and bus control in digital systems, making the 74LVC244AD suitable for various applications requiring buffering and driving of data signals.
