Frequently Asked Questions
How many differential output channels does AM26LV31IDG4 provide, and which interface standards does it comply with?
AM26LV31IDG4 provides 4 independent differential output channels and is compliant with EIA-422-B, TIA-422-B, and V.11 standards, making it a direct drop-in driver for RS-422 multi-drop buses used in industrial serial communication links.
What protection feature does AM26LV31IDG4 offer for bus fault scenarios in factory wiring environments?
AM26LV31IDG4 includes built-in driver output short-circuit protection, which limits fault current when a bus line is shorted to ground or to another signal, preventing device damage and reducing the risk of cascading failures across a shared RS-422 cable harness in factory installations.
Is AM26LV31IDG4 a suitable upgrade path from 5 V RS-422 drivers for a 3.3 V system redesign?
Yes, AM26LV31IDG4 is a low-voltage differential line driver designed to operate from a 3.3 V supply rail, making it a natural upgrade for systems transitioning away from legacy 5 V RS-422 drivers while retaining full EIA-422-B electrical compliance and the same 16-pin SOIC package footprint.
What is the high-level input current specification, and how does it affect GPIO drive requirements?
AM26LV31IDG4 specifies a maximum high-level input current of 10 µA, which is negligible compared to standard CMOS GPIO drive capability; this means the driver can be connected directly to microcontroller output pins without additional series resistors or buffer stages in most 3.3 V designs.
