ST202EAN

Drivers, Receivers, Transceivers Overview

The ST202EAN is a dual-driver, dual-receiver RS-232 transceiver designed for harsh environments. It operates from a single 5V supply and meets EIA/TIA-232E specifications at data rates up to 400 Kbits/s. The device features ±15 kV human body model ESD protection on I/O pins and guarantees a slew rate range of 3 to 30 V/µs. It requires four 0.1 µF capacitors for operation. The component is housed in a DIP-16 package and supports an extended temperature range of -40 °C to +125 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15 kV electrostatic discharge protection for transmitter outputs and receiver inputs
• Capable of guaranteed data rates up to 400 Kbits/s under standard loading conditions
• Operates with a single 5V power supply using four small 0.1 µF external capacitors

Drivers, Receivers, Transceivers Applications

• RS-232 communications in harsh industrial environments
• V.28 communication interfaces requiring high ESD tolerance
• Equipment needing extended operating temperature ranges (-40 °C to +125 °C)

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering code suffix 'AN' corresponds to the specific -40 °C to +125 °C temperature range and DIP-16 package configuration. Confirm that the required external components match the ST202E specification of four 0.1 µF capacitors rather than the 1 µF capacitors used by the ST232E variant.

Drivers, Receivers, Transceivers Selection Notes

Select this part when an RS-232 interface requires robust ESD protection and operation across a wide temperature spectrum. Ensure the design accommodates the DIP-16 footprint and utilizes the specified 0.1 µF charge pump capacitors. Compare against the ST232EAN if larger 1 µF capacitors are preferred for board space optimization.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ST202E/ST232E family of low-power RS-232 transceivers. The 'A' suffix indicates the extended temperature grade (-40 °C to +125 °C), while 'N' denotes the plastic DIP-16 package. It shares core electrical characteristics with other variants in the series but differs in thermal limits and physical form factor.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include ST202EBN (operational range -40 °C to +85 °C) and ST202ECN (operational range 0 °C to +70 °C). These parts share identical pinouts and electrical functions but offer narrower temperature capabilities.
