| ZT3483E -- Low Power 3V 250Kbps RS485 Transceivers (Features 8-pin, Half Duplex) | |
The ZT3485E series devices are 3V differential data line transceivers for RS485/RS422 communication that consist of one driver and one receiver with high level of ESD protection. They are designed for balanced transmission lines interface that meet ANSI standard TIA/EIA-485-A and ISO 8482:1987(E) specifications.
The ZT3485E series devices span out with half or full duplex, data rate guaranteed at 250Kbps or 16Mbps, and allow one unit load that fan out 32 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15kV Human Body Model (HBM).
