±15kV Human Body Model (HBM)
• Drop-in Replacements for MAX3483E, MAX3485E,
MAX3488E, MAX3490E, MAX3491E
• High fanout driving 1/8 unit load (256 devices)
available on ZT3070E Series
General Description
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) specications.
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).
Applications
• RS-422/RS-485 communications
• Utility meters
• Industrial process control
• Building automation
• Level translators
• Transceivers for EMI-sensitive applications
• Routers and HUBs
• Industrial-controlled Local Area Networks
• Industrial PCs, embedded PCs and peripherals
