NAME FUNCTION
12 14 15 AS1/NSLP
3-Level I 2 C Address Selection 1 Input (in I 2 C Mode, Table 3). In LIN bus
mode, it becomes an NSLP output, the sleep mode activation pin (active
low) to the LIN bus driver.

— 17 — DOUT3- Port 3 Negative Output
— 18 — DOUT3+ Port 3 Positive Output
— 19 17 DOUT2- Port 2 Negative Output
— 20 18 DOUT2+ Port 2 Positive Output
14 21 20 DOUT1- Port 1 Negative Output
15 22 21 DOUT1+ Port 1 Positive Output
16 23 22 DOUT0- Port 0 Negative Output
17 24 23 DOUT0+ Port 0 Positive Output
18 15, 26 16, 25 LVDSVDD
LVDS Supply Input. Bypass LVDSVDD to LVDSGND with 0.1µF and 0.01µF
capacitors as close as possible to the device.
19 27 26 SDA/TXD
I 2 C Data Link Input/LIN Tx Output. SDA/TXD becomes SDA when in I 2 C
mode and TXD when in LIN mode.
20 28 27 SCL/RXD
I 2 C Clock/LIN Rx Input. SCL/RXD becomes SCL when in I 2 C mode and RXD
when in LIN mode.
— 29 28 S5 Routing Selection 5 Input. See Tables 6a and 6b.
— 30 29 S4 Routing Selection 4 Input. See Tables 6a and 6b.
— — 32 DGND Digital Ground
— — — EP
Exposed Pad. Internally connected to GND. Connect to a large ground
plane to maximize thermal performance.
