NV7342x ALYW NCV7342 High Speed Low Power CAN Transceiver Description The NCV7342 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical www.onsemi.com bus and may be used in both 12 V and 24 V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. 8 The NCV7342 is an addition to the CAN highspeed transceiver family complementing NCV734x CAN standalone transceivers and 1 1 previous generations such as AMIS42665, AMIS3066x, etc. SOIC8 DFN8 D SUFFIX MW SUFFIX Due to the wide commonmode voltage range of the receiver inputs CASE 751AZ CASE 506DG and other design features, the NCV7342 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent MARKING DIAGRAMS matching of the output signals. 8 Features 1 NV7342x NV7342x Compatible with the ISO 118982, ISO 118985 Standards ALYW ALYW High Speed (up to 1 Mbps) V Pin on NCV73423 Version Allowing Direct Interfacing with IO 1 3 V to 5 V Microcontrollers NV7342x= Specific Device Code V Pin on NCV73420 Version for Bus Common Mode SPLIT x = 0 or 3 Stabilization A = Assembly Location Very Low Current Consumption in Standby Mode with Wakeup via L = Wafer Lot the Bus Y = Year W = Work Week Excellent Electromagnetic Susceptibility (EMS) Level Over Full = PbFree Package Frequency Range.
