NAME FUNCTION

12 14 15 AS1/NSLP

3-Level I

C Address Selection 1 Input (in I

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

C Data Link Input/LIN Tx Output. SDA/TXD becomes SDA when in I

mode and TXD when in LIN mode.

20 28 27 SCL/RXD

C Clock/LIN Rx Input. SCL/RXD becomes SCL when in I

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.
