3.3V CMOS 16-Bit Bus Transceiver with 3-State Outputs, 5.0V Tolerant I/O, and Bus-Hold
Jump to Page Section:
Overview
Description
The 74LVCHR162245A is a high-speed, low power, 16-bit bus transceiver that is ideal for asynchronous communication between two buses. The Direction and Output Enable controls allow operation as either two independent 8-bit transceivers or one 16-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 LVCHR162245A has "bus-hold" which eliminates the need for pull-up/down resistors. The 74LVCHR162245A operates at -40C to +85C
