Description and Introduction
Octal Bi-Directional Transceiver with 3-STATE Outputs The 74ABT245CSC is a high-performance BiCMOS device manufactured by Fairchild Semiconductor. It is an octal bus transceiver with 3-state outputs, designed for asynchronous communication between data buses. The device features non-inverting 3-state bus compatible outputs in both send and receive directions. It operates with a supply voltage range of 4.5V to 5.5V and is characterized for operation from -40°C to 85°C. The 74ABT245CSC is available in a 20-pin small-outline integrated circuit (SOIC) package. It supports bidirectional data flow and has a typical propagation delay of 3.5 ns, making it suitable for high-speed applications. The device also includes bus-hold circuitry to retain the last valid logic state on the inputs, reducing the need for external pull-up or pull-down resistors.
