技术特性

• 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
• 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
