The 74ALVCH16245 16-bit bus transceiver is designed for asynchronous communication between data buses and can be used as two 8-bit transceivers or one 16-bit transceiver. The 74ALVCH16245 has "bus-hold" which prevents floating inputs and eliminates the need for pull-up/down resistors. The 74ALVCH16245 operates at -40C to +85C
