ZT207E/ZT208E/ZT211E/ZT213E/ZT213AE
Low Power 5V 250Kbps RS232 Transceivers
Copyright © 2010-2017 ASIX Electronics Corporation. All rights reserved.
General Description
The ZT213E series devices are +5V powered EIA/TIA-232
and
V.28/V.24
communication
interfaces
with
low
power
requirements.
These
transceivers
consist
of
combinations
up to five line drivers, five line receivers and the proprietary
switch-capacitor regulated voltage converters.
The ZT211E
and ZT213E/AE feature a low power shutdown mode which
draws as little current as 1μA typical with receiver outputs tri-
stated and in wake-up.
These devices operate from a single
+5V power supply at the guaranteed data rate of 250K bits/sec
with enhanced electrostatic discharge (ESD) protection in all
RS232 I/O pins exceeding ±15KV HBM.
Applications
• Battery-Powered Applications
• Notebooks, Subnotebooks, and Palmtops
• Industrial and Embedded PCs
• Data Cables for Cell Phones and PDAs
• Terminal Adapters and POS terminals
• Peripherals interface
• Routers and HUBs
Features
• Meets EIA/TIA-232F and CCITT V.28/V.24
specifications
for
V
CC
at
+5V
±10%
• Low Quiescent Current – 3mA.
• Low Shutdown Current (where applicable) -
1μA typical, 10μA max.
• Guaranteed Standard Data Rate 250Kbps
• Proprietary Switch-Capacitor Regulated Voltage
Converters (patent pending)
• Wake Up Feature in Shutdown Mode
• Tri-State Receiver Outputs
• Latch-up Free
• ESD Protection for RS-232 I/O's
±15KV Human Body Model (HBM)

Storage
Considerations
Storage
in
a
low
humidity
environment
is
preferred.
Large
high
density
plastic
packages
are
moisture
sensitive
and
should be stored in Dry Vapor Barrier Bags. Prior to usage,
the parts should remain bagged and stored below 40°C and
60%RH. If the parts are removed from the bag, they should
be used within 168 hours or stored in an environment at or
below 20%RH. If the above conditions cannot be followed,
the parts should be baked for 12 hours at 125°C in order to
remove moisture prior to soldering. ASIX ships product in
Dry
Vapor
Barrier
Bags
with
a
humidity
indicator
card
and
desiccant
pack.
The
humidity
indicator
should
be
below
30%RH. The MSL of this product is 3.

Absolute
Maximum
Ratings
These are stress ratings only and functional operation of
the device at these ratings or any other above those indicated in
the operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods of time may affect reliability.
