MAX14841E Datasheet | Maxim Integrated

MAX14840E/MAX14841E 40Mbps, +3.3V, RS-485 Half-Duplex Transceivers General Description The MAX14840E/MAX14841E are +3.3V ESD-protected transceivers intended for half-duplex RS-485 munication up to 40Mbps. These transceivers are optimized for high speeds over extended cable runs while maximizing tolerance to noise. The MAX14840E Features symmetrical fail-safe and larger receiver hysteresis, providing improved noise rejection and improved recovered signals in high-speed and long cable applications. The MAX14841E has true fail-safe receiver inputs guaranteeing a logic-high receiver output when inputs are shorted or open. The MAX14840E/MAX14841E are available in 8-pin SO and small, 8-pin (3mm x 3mm) TDFN-EP packages. Both devices operate over the -40NC to +125NC temperature range.
