DESCRIPTION

The L9637D is a monolithic integrated circuit containing standard ISO 9141 compatible interface functions.

ABSOLUTE MAXIMUM RATINGS (No damage or latch)

Note: Max. ESD voltages are ±2kV with human body model C = 100pF, R = 1.5k corresponds to maximum energy dissipation 0.2mJ according to MIL883C.
