Product details

Industrial temperature range and noise margin

The MAX14770EESA+T: The 50 mV receiver hysteresis provides a noise margin that rejects common-mode transients on long RS-485 cable runs, reducing false bit transitions on a busy bus.

Supply voltage and 5V RS-485 compatibility

Operating from a single 4.5V to 5.5V supply, the MAX14770EESA+T is designed for 5V RS-485 systems. The 20 Mbps data rate supports high-speed polling or streaming over twisted-pair cabling without the throughput bottleneck of slower transceivers. The half-duplex architecture means the driver and receiver share the same bus pair — the host MCU controls the direction pin to switch between transmit and receive.

Frequently asked questions

Is MAX14770EESA+T a direct replacement for MAX14770EESA?

The suffix +T indicates tape-and-reel packaging. The die and electrical specifications are identical to the non-tape version — the same transceiver in the same 8-SOIC package. The +T variant is the reeled option for automated assembly.

Does MAX14770EESA+T support 5V RS485 systems?

Yes. The supply voltage range is 4.5V to 5.5V, which covers the standard 5V RS-485 bus voltage. The 50 mV receiver hysteresis ensures reliable data reception in noisy industrial environments.
