The TPT9H111 is a 3.3V Multipoint-Low-Voltage Differential (M-LVDS) line driver and receiver, which can support 100 Mbps data rates. Driver outputs and receiver inputs are protected against ±8kV ESD strikes without latch-up. The driver output has been designed to support multipoint buses with the loads no less than 30 Ω, and can support the controlled slew rate on drivers. The TPT9H111 is Type-1 receiver that detects the bus state with a differential input of 50 mV over a common-mode voltage range of -1 V to 3.4 V. The receivers exhibit 25 mV of differential input voltage hysteresis to prevent output oscillations with slowly changing signals or loss of input. 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.
