Low Power 5V 250kbps/10Mbps RS485 Transceivers

Features

GeneralDescription

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.

• 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 unit load (32 devices) on the same

common bus

TheZT485Eseriesdevicesspansoutwithhalforfullduplex,

data rate guaranteed at 250k bit per second or 10Mbps, and

allowoneunitloadthatfanout32devicessharingacommon

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 MAX483E, MAX485E,
