LTC1682CMS8-3.3#TRPBF

Product Summary

The LTC1682CMS8-3.3#TRPBF is a high speed, precision delay RS485 transceiver that can operate at data rates as high as 52Mbps. The LTC1682CMS8-3.3#TRPBF also meets the requirements of RS422. A unique architecture provides very stable propagation delays and low skew over a wide common mode and ambient temperature range. The driver and receiver of LTC1685CS8 feature three-state outputs, with disabled driver outputs maintaining high impedance over the entire common mode range. A short circuit feature detects shorted outputs and substantially reduces driver output current. The receiver of LTC1682CMS8-3.3#TRPBF has a fail-safe feature that guarantees a high output state when the inputs are shorted or are left floating. The LTC1682CMS8-3.3#TRPBF RS485 transceiver guarantees receiver failsafe operation over the entire common mode range (–7V to 12V). Input resistance will remain ≥22k when the device is unpowered or disabled.
