Additional Details
The PI74FCT244ATSX features two output enable (OE) inputs, each controlling four of the eight outputs. When OE is high, the corresponding outputs are disabled and in a high-impedance state. The device is designed to minimize ground bounce and ensure clean signal transmission. Datasheet specifications provide the operating temperature range, supply voltage range, and detailed electrical characteristics. This is a non-inverting buffer, frequently used in telecom and industrial applications to improve signal strength and reliability. The 'SX' suffix typically refers to a specific packaging variant or operating temperature range. Consult the datasheet for precise details.
