The ADN4691E / ADN4693E / ADN4696E / ADN4697E are multipoint, low voltage differential signaling (M-LVDS) transceivers (driver and receiver pairs) that can operate at up to 200 Mbps (100 MHz). The receivers detect the bus state with a differential input of as little as 50 mV over a common-mode voltage range of −1 V to +3.4 V. ESD protection of up to ±15 kV is implemented on the bus pins. The devices adhere to the TIA/EIA-899 standard for M-LVDS and complement TIA/EIA- 644 LVDS devices with additional multipoint capabilities.

The ADN4691E / ADN4693E are Type 1 receivers with 25 mV of hysteresis so that slow-changing signals or loss of input does not lead to output oscillations. The ADN4696E / ADN4697E are Type 2 receivers exhibiting an offset threshold, guaranteeing the output state when the bus is idle (bus-idle fail-safe) or the inputs are open (open-circuit fail-safe).

The devices are available as half-duplex in an 8-lead SOIC package (the ADN4691E / ADN4696E) or as full-duplex in a 14-lead SOIC package (the ADN4693E / ADN4697E).
