The SN75LBC184D is a differential line transceiver made by Texas Instruments. It is a high-speed, high-frequency component designed for use in local area networks (LANs). It is capable of data rates up to 10 Mbps, and is compatible with both the IEEE 802.3 (Ethernet) and IEEE 802.4 (Token Bus) standards. The SN75LBC184D is designed to provide an interface between two twisted-pair cables, allowing for isolation between the two cables. It can be used in applications such as repeater, bridge, or point-to-point link. It features built-in receivers, drivers, a data rate indicator LED, error detection, and a differential data input/output. It also features a high speed, low-power mode with current draw of less than 200 mA.
