Frequently Asked Questions

What is the operating voltage range of the TRS3232CDR?

The TRS3232CDR operates from a 3V to 5.5V single supply, making it compatible with both 3.3V and 5V logic systems. This wide range simplifies design in mixed-voltage environments common in modern embedded and industrial applications.

What ESD protection level does the TRS3232CDR provide?

The TRS3232CDR provides ±15kV ESD protection (Human Body Model) on all RS-232 input and output pins. This high level of protection helps prevent damage from electrostatic discharge during handling and in-field operation, reducing system failure rates significantly.

What package does the TRS3232CDR come in and how many drivers/receivers does it have?

The TRS3232CDR is available in a 16-pin Small Outline (SOIC) package. It integrates two RS-232 drivers and two receivers, enabling full-duplex serial communication in a compact footprint suitable for space-constrained PCB designs.

What interface standards is the TRS3232CDR compatible with?

The TRS3232CDR is compliant with EIA-232-F, TIA-232-F, and ITU V.28 interface standards. This broad compatibility ensures seamless interoperability with legacy and modern RS-232 serial communication equipment across industrial, medical, and consumer applications.
