74LVCH32245A - Block Diagram


3.3V CMOS 32-Bit Bus Transceiver with 3-State Outputs, 5.0V Tolerant I/O, and Bus-Hold

The 74LVCH32245A high-speed, low power 32-bit bus transceiver is ideal for asynchronous communication between two busses. The Direction and Output Enable controls are designed to operate the device as either four independent 8-bit transceivers or one 32-bit transceiver. All pins can be driven from either 3.3V or 5V devices allowing the use of this device as a translator in a mixed 3.3V/5V supply system. The 74LVCH32245A has “bus-hold” which eliminates the need for pull-up/down resistors. The 74LVCH32245A operates at -40C to +85C
