General Description

The ZT230F series devices are 5V powered EIA/TIA-232

and V.28/V.24 communication interfaces with low power

requirements. They consist of the combinations of ﬁ ve line

drivers, ﬁ ve line receivers and the proprietary switch-capaci-

tor regulated voltage converters. The ZT211F and ZT213F

feature a low power shutdown mode which draws as little

current as 1μA typical with receiver outputs tri-stated and

wake-up function. These devices operate from a single 5V

power supply at the guaranteed data rate of 1000k 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

speciﬁ cations for V

at +5V ±10%

• Low Quiescent Current – 3mA typ., 6mA max.

• Low Shutdown Current (where applicable) -

1μA typical, 10μA max.

• Guaranteed Standard Data Rate 1000kbps

• 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)

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 speciﬁ cations is not implied.

Exposure to absolute maximum rating conditions for extended

periods of time may affect reliability.

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 48 hours or stored in an environment at or

below 20%RH. If the above conditions cannot be followed,

the parts should be baked for four hours at 125°C in order

remove moisture prior to soldering. Zywyn ships product in Dry

Vapor Barrier Bags with a humidity indicator card and desic-

cant pack. The humidity indicator should be below 30%RH.

The information furnished by Zywyn has been carefully

reviewed for accuracy and reliability. Its application or use,

however, is solely the responsibility of the user. No responsibil-

ity of the use of this information become part of the terms and

conditions of any subsequent sales agreement with Zywyn.

Speciﬁ cations are subject to change without the responsibility

for any infringement of patents or other rights of third parties

which may result from its use. No license or proprietary rights

are granted by implication or otherwise under any patent or

patent rights of Zywyn Corporation.
