Additional Details

The PI74ALVCH16245V operates from a supply voltage of 2.3V to 3.6V. It typically has a propagation delay of around 3 ns, enabling high-frequency operation. The direction control input determines the direction of data flow through the transceiver. The 3-state outputs allow the device to be effectively disconnected from the bus when not transmitting or receiving, preventing bus contention. The hot insertion capability allows the device to be inserted or removed from a live system without causing disruptions. The operating temperature range is typically -40°C to +85°C.
