Low Power 5V 250kbps/10Mbps 128-Fanout RS485 Transceivers

Features

GeneralDescription

The ZT485ER 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.

• Meets or exceeds the requirements of ANSI Stan-

dard TIA/EIA-485-A and ISO 8482:1987(E) specifi-

cations for V at +5V ±5%

• Low quiescent current – 0.5mA typ., 1mA max.

• Low shutdown current (where applicable) - 0.01µA

typical, 10µA max.

• Guaranteed standard data rate 250kbps or 10Mbps

• Thermal shutdown protection

• -7V to +12V common-mode input voltage range

• Half-Duplex or Full-Duplex configuration

• Allows up to 1/4 unit load (128 devices) on the

same common bus

The ZT485ER series devices spans out with half or full

duplex, data rate guaranteed at 250k bit per second or

10Mbps, andallowone-fourthofanunitloadthatfanout128

devices sharing a common bus. The I/Os are enhanced-

electrostatic discharge (ESD) protected, exceeding ±15kV

Human Body Model (HBM).

• 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 MAX487E, MAX3291,

MAX3292,SN75LBC182,SN65LBC182

• Standard fanout driving 1 unit load (32 devices)

available on the ZT485E Series

Applications

• RS422/RS485 communications
