Overview

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).

Features

● Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for V cc at +3.3V ±10%

● Low quiescent current – 0.5mA typ., 1.5mA max
● Low shutdown current (where applicable) - 0.05μA typical, 10μA max
● Guaranteed standard data rate 250Kbps or 16Mbps
● True Fail-Safe (Open and Short) Receiver
● -7V to +12V common-mode input voltage range
● Half-Duplex or Full-Duplex configuration
● Allows up to 1 unit load (32 devices) on the same common bus
● Controlled driver output slew rate and receiver input filtering
● Active-high driver enable and active-low receiver enable
● ESD Protection on bus terminals
-- ±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
