ATA6560-GAQW-VAO from Microchip, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TXD input Transmit Data Input from the CAN controller. Internal pull-up (RTXD ~35 kΩ typ, 20-50 kΩ) to VIO ensures a defined recessive state if left floating. Logic thresholds are VIL ≤ 0.3×VVIO and VIH ≥ 0.7×VVIO. A low level for longer than tto(dom)TXD triggers the TXD dominant time-out and releases the bus to recessive.
2 GND power_in Ground Supply (0 V reference). All voltages in the datasheet are defined with respect to this pin. On the VDFN package the exposed thermal pad is internally connected to GND and must be tied to ground.
3 VCC power_in Main supply voltage, 4.5 V to 5.5 V (nominal 5 V). Recommend a 100 nF decoupling capacitor to GND. Supply current is typ. 50 mA dominant, 2-5 mA recessive, and ~7 µA in Standby mode. Undervoltage detection threshold Vuvd(VCC) is 2.75-4.5 V; the transceiver disengages from the bus below this.
4 RXD output Receive Data Output; reports the state of the CAN bus (LOW = dominant, HIGH = recessive) to the microcontroller. Push-pull output referenced to VIO (which is internally tied to VCC on the ATA6560). Also switched LOW to signal a wake-up request when a valid wake-up pattern is detected on the bus in Standby mode.
5 NSIL input Silent-mode control input, active LOW (ATA6560 only). With STBY = LOW: NSIL = HIGH selects Normal mode, NSIL = LOW selects Silent (receive-only) mode where the transmitter is disabled. Internal pull-up (Rpu 75-175 kΩ, typ. 125 kΩ) to VIO ensures a defined HIGH state if left open. Microchip recommends keeping NSIL HIGH in Standby to minimize IVIO.
6 CANL bidirectional Low-level CAN bus line. Differential CAN transceiver output/input; driven low in the dominant state and biased to VCC/2 (Normal mode) or to GND (Standby mode). Protected against short-circuit to GND or a positive supply, transient-protected per ISO 7637-2 (-150 V to +100 V), and rated for ±8 kV ESD (IEC 61000-4-2) at pin level.
7 CANH bidirectional High-level CAN bus line. Differential CAN transceiver output/input; driven high in the dominant state and biased to VCC/2 (Normal mode) or to GND (Standby mode). Same short-circuit, transient, and ESD protection as CANL. Connect via the network's 60 Ω differential termination (typically two 60 Ω resistors or 120 Ω at each bus end).
8 STBY input Standby-mode control input. LOW = Normal (or Silent) mode, HIGH = low-power Standby mode (transmitter and HSC off; only the wake-up comparator monitors the bus). Internal pull-up (Rpu 75-175 kΩ, typ. 125 kΩ) to VIO puts the device in Standby by default if the pin is left floating. Logic thresholds are VIL ≤ 0.3×VVIO and VIH ≥ 0.7×VVIO.
