ADM4851ARZ-REEL7

ADM4851 is a differential line transceiver suitable for high speed, half-duplex data communication on multipoint bus transmission lines. This device is half-duplex transceiver that share differential lines and have separate enable inputs for the driver and receiver. This device has a 1/8-unit load receiver input impedance, which allows upto 256 transceivers on one bus. Because only one driver must be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus. The receiver inputs have a true fail-safe feature, which ensures a logic high output level when the inputs are open or shorted. It is widely used in application such as low power RS-485 applications, EMI sensitive systems, DTE to DCE interfaces, industrial control, packet switching, local area networks, level translators etc.

• Data rate is 500kbps

• Rise/fall times is 200ns min to 600ns max
• Operating temperature is −40°C to +85°C
• Package style is 8-lead standard small outline package [SOIC-N]
