Active RS-485/422 transceiver for 3.3 V industrial buses
The Texas Instruments SN65HVD1474DGK is a full-duplex RS-485/RS-422 transceiver in an 8-VSSOP package, rated for 20 Mbps signaling over differential twisted-pair cables.
125°C rating — motor-drive and under-hood capable
The 70 mV hysteresis helps reject common-mode noise on long cable runs in electrically noisy environments like variable-frequency drives.
The logic inputs and outputs are 3.3 V compatible, so it interfaces directly with 3.3 V UARTs without level shifting. For 5 V systems, look at the SN65HVD14xx family variants with wider supply range.
The base product number 65HVD1474 covers the family; the DGK suffix denotes the 8-VSSOP package.
