Product Details

The MAX14840E/MAX14841E are +3.3V ESD-protected transceivers intended for half-duplex RS-485 communication 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 -40°C to +125°C automotive temperature range.
