Ultralow Power RS-485/RS-422 Transceiver; • 250 kbps data rate \n\n• Glitch-free driver power-up allows\n hot connection \n\n• Driver maintains high output \nimpedance with power off \n\n• Low power—120 µA max ICC with driver disabled \n\n• High input impedance—up to 256 transceivers on bus \n\n\n\n• Wide common-mode range allows\n ±7 V ground differences between \ndevices \n\n• Low current (1 µA) shutdown mode \n\n• Pin compatible with industry \nstandard 75176 \n\n• Slew rate control for error-free data transmission and low EMI \n\n• ±10 kV ESD protection (human body model) on RS-485 I/O pins;

The ADM1487 is an ultralow power RS-485/RS-422 transceiverconsisting of one driver and one receiver per package. Quiescentoperating current is typically 80 µA and 1 µA in shutdown mode.The driver and receiver both have three-state outputs. This allows multiple drivers to be connected to an RS-485/RS-422 bus or several receiver outputs to be connected to a serial data bus. The driver will maintain a high impedance output state even with power off, while the receiver features fail-safe operation that guarantees a logic high output if the inputs are left open circuit.\n\nThe device has slew rate limited drivers to minimize electromagnetic interference (EMI) and reduce reflections caused by incorrectly terminated cable.\n\n\n\n
