The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common−mode voltage range of the receiver inputs, the AMIS−30660 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals. http://onsemi.com MARKING DIAGRAM 8 8 1 1 • • • • • • PIN ASSIGNMENT TxD 1 8 S GND 2 7 CANH VCC 3 6 CANL RxD 4 5 Vref AMIS− 30660 • • • • Fully Compatible with the ISO 11898−2 Standard Certified “Authentication on CAN Transceiver Conformance (d1.1)” High Speed (up to 1 Mbit/s) Ideally Suited for 12 V and 24 V Industrial and Automotive Applications Low EME Common−Mode Choke is No Longer Required Differential Receiver with Wide Common−Mode Range ($35 V) for High EMS No Disturbance of the Bus Lines with an Unpowered Node Transmit Data (TxD) Dominant Time−out Function Thermal Protection Bus Pins Protected Against Transients in an Automotive Environment Silent Mode in which the Transmitter is Disabled Short Circuit Proof to Supply Voltage and Ground Logic Level Inputs Compatible with 3.3 V Devices These are Pb−Free Devices* 30660−2 ALYW G 30660−2 = Specific Device Code A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package Features • • • • SOIC−8 CASE 751 PC20040918.3 (Top View) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 9 of this data sheet. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2012 August, 2012 − Rev. 10 1 Publication Order Number: AMIS−30660/D AMIS−30660 Table 1.

In case the device is powered, one of two operating modes can be selected through Pin S. Table 5. FUNCTIONAL TABLE OF AMIS−30660 (X = DON’T CARE) VCC Pin TxD Pin S Pin CANH Pin CANL Bus State Pin RxD 4.75 V to 5.25 V 0 0 (or Floating) High Low Dominant 0 4.75 V to 5.25 V X 1 VCC / 2 VCC / 2 Recessive 1 4.75 V to 5.25 V 1 (or Floating) X VCC / 2 VCC / 2 Recessive 1 VCC < PORL (Unpowered) X X 0 V < CANH < VCC 0 V < CANL < VCC Recessive 1 PORL < VCC < 4.75 V >2V X 0 V < CANH < VCC 0 V < CANL < VCC Recessive 1 High−Speed Mode circuit is particularly necessary when a bus line short−circuits. If Pin S is pulled low (or left floating), the transceiver is in its high−speed mode and is able to communicate via the bus lines. The signals are transmitted and received to the CAN controller via the Pins TxD and RxD. The slopes on the bus line outputs are optimized to give extremely low electromagnetic emissions. TxD Dominant Time−out Function A TxD dominant time−out timer circuit prevents the bus lines from being driven to a permanent dominant state (blocking all network communication) if Pin TxD is forced permanently low by a hardware and/or software application failure. The timer is triggered by a negative edge on pin TxD. If the duration of the low−level on Pin TxD exceeds the internal timer value tdom, the transmitter is disabled, driving the bus into a recessive state. The timer is reset by a positive edge on Pin TxD. Silent Mode In silent mode, the transmitter is disabled. All other IC functions continue to operate. The silent mode is selected by connecting Pin S to VCC and can be used to prevent network communication from being blocked, due to a CAN controller which is out of control. Fail−Safe Features Overtemperature Detection A current−limiting circuit protects the transmitter output stage from damage caused by an accidental short−circuit to either positive or negative supply voltage, although power dissipation increases during this fault condition. The Pins CANH and CANL are protected from automotive electrical transients (according to “ISO 7637”; see Figure 3). Pin TxD is pulled high internally should the input become disconnected. A thermal protection circuit protects the IC from damage by switching off the transmitter if the junction temperature exceeds a value of approximately 160°C. Because the transmitter dissipates most of the power, the power dissipation and temperature of the IC is reduced. All other IC functions continue to operate. The transmitter off−state resets when Pin TxD goes high.
