TB5D1M数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

These quad differential drivers are TTL input to pseudo-ECL differential output used for digital data transmission over balanced transmission lines.The TB5D1M device is a pin and functional replacement for the Agere systems BDG1A and BPNGA quad differential drivers. The TB5D1M has a built-in lightning protection circuit to absorb large transitions on the transmission lines without destroying the device. When the circuit is powered down it loads the transmission line, because of the protection circuit. The TB5D2H device is a pin and functional replacement for the Agere systems BDG1A and BDGLA quad differential drivers. Upon power down the TB5D2H output circuit appears as an open circuit and does not load the transmission line.Both drivers feature a 3-state output with a third-state level of less than 0.1 V.The packaging options available for these quad differential line drivers include a 16-pin SOIC gull-wing (DW) and a 16-pin SOIC (D) package.Both drivers are characterized for operation from -40°C to 85°CThe logic inputs of this device include internal pull-up resistors of approximately 40 k that are connected to VCC to ensure a logical high level input if the inputs are open circuited.
