The TPT9H221 is a 3.3V Multipoint-Low-Voltage Differential (M-LVDS) line driver and receiver, which can operate at signaling rates up to 200 Mbps. Driver outputs and receiver inputs are protected against ±8kV ESD strikes without latch-up. The driver output has been designed to support multipoint buses presenting loads as low as 30 Ω, and incorporates controlled transition times to allow for stubs off of the backbone transmission line.

The TPT9H221 is Type-2 receiver that detect the bus state with a differential input of 50 mV over a common-mode voltage range of -1 V to 3.4 V. Type-2 receiver includes an offset threshold to provide a known output state under open-circuit fail-safe, idlebus fail-safe. The device is characterized for operation from –40°C to 85°C. The device is available as half-duplex in an 8-lead SOP package.
