Frequently Asked Questions

How many driver and receiver channels does the ST3232ECTR provide?

The ST3232ECTR is built in a 16-pin TSSOP package and integrates 2 drivers with 2 receivers, delivering full-duplex RS-232 communication that complies with EIA-232, TIA-232, V.24 and V.28 standards for legacy serial interfaces.

Why does the ST3232ECTR use Schmitt-trigger receiver inputs?

Schmitt-trigger inputs give the ST3232ECTR hysteresis that rejects slow edges and noise on RS-232 lines, while the high-level input leakage current stays below 1 uA, helping maintain signal integrity in electrically noisy industrial environments.

What lead time should buyers plan for when sourcing the ST3232ECTR?

STMicroelectronics quotes a factory lead time of 10 weeks for the 16-pin ST3232ECTR, so procurement teams should place orders early for production builds; the part also carries a JESD-609 e3 lead-free finish for RoHS-compliant assembly.

Which end systems typically use the ST3232ECTR for serial communication?

Equipment such as PLCs, POS terminals, and industrial control panels use the ST3232ECTR to convert UART signals into RS-232 voltage levels across 2 channels compliant with EIA-232 and V.28, enabling reliable serial links in factory automation and legacy instrumentation ports.
