Description and Introduction
Octal Bi-Directional Transceiver with 3-STATE Outputs The 74ABT245CMTCX 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 74ABT245CMTCX is available in a 20-pin TSSOP package. Key specifications include a typical propagation delay of 3.5 ns and a typical output skew of 0.5 ns. It supports bidirectional data flow controlled by the direction (DIR) input and has an output enable (OE) input to disable the outputs, placing them in a high-impedance state. The device is designed to interface with 5V TTL and 3.3V LVTTL systems.
