Additional Details

The MC74F244ND operates from a 5V power supply. It is available in a 20-pin DIP package. This device features two Output Enable (OE) inputs, each controlling four of the eight buffer/drivers. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state. This allows for selective enabling and disabling of different sections of the buffer.

The operating temperature range is typically between 0°C and +70°C. Proper power supply decoupling is essential for stable operation. The device is designed to meet or exceed JEDEC standards. The propagation delay is typically in the range of 4 to 6 ns, making it suitable for high-speed applications.
