GM75176E

GM75176E is a ±15kV ESD-protected high-speed transceiver for RS-485/RS-422 communications, incorporating one driver and one receiver. The device features a fail-safe circuit that guarantees a logic-high output at the receiver when the receiver inputs are open or shorted. This means that if all transmitters on the terminated bus are disabled (high-impedance state), the receiver output will be at a logic-high level. GM75176E is equipped with reduced slew-rate drivers, which minimize EMI and reduce reflections caused by improper cable termination, enabling error-free data transmission at speeds up to 10Mbps. In addition, the receiver of GM75176E features a 1-unit-load input impedance, allowing up to 32 transceivers to be connected to the bus. GM75176E is designed for half-duplex communication and incorporates over-temperature protection to prevent damage under high-temperature conditions.
