Description

The 74HC244PW is a high-speed CMOS octal buffer/line driver with 3-state outputs, manufactured by Nexperia and other semiconductor companies. It's part of the 74HC series of logic devices, which are known for their high speed and low power consumption. This specific device features two groups of four buffers, each with independent enable inputs.
Key features of the 74HC244PW include:
- High-Speed Operation: Capable of operating with a typical propagation delay of around 10ns at 5V.
- 3-State Outputs: Allows the outputs to be in one of three states - high, low, or high impedance, facilitating bus-oriented applications.
- Wide Voltage Range: Operates typically between 2V and 6V, making it suitable for both TTL and CMOS logic levels.
- Current Drive Capability: Can source/sink up to 6mA, suitable for driving moderate loads.
The 74HC244PW is commonly used in digital systems for buffering data lines, preventing signal degradation over long distances, and isolating different parts of a circuit. Its small outline package (TSSOP) makes it suitable for compact electronic designs.

Pinout

The 74HC244PW is a high-speed CMOS octal buffer/line driver with 3-state outputs. It features 20 pins in total. The pin configuration and functions are as follows:
1. Pin Count: 20 pins.
2. Functions:
- Data Inputs: A0 to A7 (Pins 2, 3, 4, 5, 11, 12, 13, 14)
- Data Outputs: Y0 to Y7 (Pins 18, 17, 16, 15, 9, 8, 7, 6)
- Enable Inputs: OE1 (Pin 1), OE2 (Pin 19)
- Ground (GND): Pin 10
- Supply Voltage (VCC): Pin 20
The device operates as two 4-bit buffers or line drivers with separate output enable pins. When the output enable (OE) is low, the corresponding section of the device is enabled and functions as a buffer; when OE is high, the outputs are in a high-impedance state. This device is commonly used for bus interface or signal buffering due to its ability to drive high fan-out loads.
