DESCRIPTION
The TJ3485 is a low-power half-duplex transceiver that meets the specifications of RS-485 and RS-422. IC contains one driver and one receiver. The driver slew rates is not limited, allowing them to transmit up to 5Mbps. These transceivers draw between 120uA and 500uA of supply current when unloaded or fully loaded with disabled drivers. All parts operate from a single 3.3V supply. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance states. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The ESD tolerance is more than ±8kV for both Human Body Model and ±15kV for IEC61000-4-2 Air Discharge Method on this device.

TJ3485 低功耗，斜率受限的RS-485 / RS-422收發器
描述
TJ3485是一款低功耗半雙工收發器，符合RS-485和RS-422的規格。 IC包含一個驅動器和一個接收器。 驅動器的擺率不受限制，允許它們傳輸高達5Mbps的速度。 這些收發器在空載或禁用驅動器滿載時消耗120uA至500uA的電源電流。 所有部件均採用3.3V單電源供電。 驅動器受短路電流限制，並通過熱關斷電路保護其免受過大的功耗，該電路將驅動器輸出置於高阻態。 接收器輸入具有故障安全功能，如果輸入開路，則保證邏輯高輸出。 在此設備上，人體模型的ESD容忍度均超過±8kV，IEC61000-4-2空氣放電方法的ESD容忍度則為±15kV。
特徵
- 3.3V單電源
