Overview
L9637 Monolithic bus driver with ISO 9141 interface Features ■ Operating power supply voltage range 4.
5 V  VS  36 V (40 V for transients) ■ Reverse supply (battery) protected down to VS  -24 V ■ Standby mode with very low current consumption ISSB 1 mA @ VCC 0.
5 V ■ Low quiescent current in off condition ISOFF = 120 µA ■ TTL compatible TX input ■ Bidirectional K-I/O pin with supply voltage dependent input threshold ■ Overtemperature shut down function Selective to K-I/O pin ■ Wide input and output voltage range -24 V  VK  VS ■ K output current limitation, typ.
IK = 60 mA ■ Defined OFF output status in undervoltage condition and VS or GND interruption ■ Controlled output slope for low EMI SO8 ■ High input impedance for open VS or GND connection ■ Defined output ON status of LO or RX for open LI or K inputs ■ Defined K output OFF for TX input open ■ Integrated pull up resistors for TX, RX and LO ■ EMI robustness optimized Description The L9637 is a monolithic integrated circuit containing standard ISO 9141 compatible interface functions.
