Frequently Asked Questions

How many drivers and receivers does the ST3232CDR integrate for RS-232 links?

The ST3232CDR integrates 2 line drivers and 2 receivers with Schmitt-trigger inputs, and it operates from a single 3V to 5.5V supply while supporting EIA-232, TIA-232, V.24, and V.28 standards for a complete duplex serial channel.

What supply voltage range does the ST3232CDR require to operate?

This transceiver operates from a single 3V to 5.5V supply rail and can achieve data rates up to 250 kbps, making it suitable for low-voltage embedded systems that still need legacy RS-232 connectivity.

Which package option and lead time should buyers plan for when sourcing the ST3232CDR?

The ST3232CDR ships in a lead-free 16-pin SOP-16 package, and typical factory lead time runs around 10 weeks, so procurement teams should plan orders accordingly for production schedules.
