簡介

The ZT485E series devices are 5V 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 ZT485E series devices span out with half or full duplex, data rate guaranteed at 250K bit per second or 10Mbps, 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).

規格:

● Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for Vcc at +5V ±10%

● Low quiescent current - 0.5mA typ., 1mA max
● Low shutdown current (where applicable) - 1μA typical, 10μA max
● Guaranteed standard data rate 250Kbps or 10Mbps
● 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 MAX483E, MAX485E, MAX488E, MAX489E, MAX490E, MAX491E
● High fanout driving 1/8 unit load (256 devices) available on the ZT485H Series
