SN65HVD1782DR

RS485 приемопередатчик, полудуплексный, 1 драйвер, до 10МБ/с, защита от ЭСР, 3.15 В до 5.5В, SOIC-8.

The SN65HVD1782DR is a RS-485 Fault-protected Transceiver designed to survive over-voltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes and tool mis-applications. The device is also robust to ESD events with high levels of protection to the human-body-model specification. The SN65HVD178x device combines a differential driver and a differential receiver, which operate from a single power supply. In the SN65HVD1782, the driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. This port features a wide common-mode voltage range, making the device suitable for multipoint applications over long cable runs. This device is pin-compatible with the industry standard SN75176 transceiver, making them drop-in upgrades in most systems.
