Frequently Asked Questions
What is the supply voltage range for TRS3232EIDR?
TRS3232EIDR operates from a 3.3V supply (3.0V to 3.6V). It uses an internal charge pump to generate the ±5.5V voltages required for RS-232 compliant output levels, eliminating the need for an external dual supply.
What ESD protection level does TRS3232EIDR provide on RS-232 pins?
The RS-232 I/O pins of TRS3232EIDR are protected against ±15kV electrostatic discharge (ESD) using the Human Body Model, making it robust for industrial environments where cables can accumulate significant static charge.
What is the maximum data rate supported by TRS3232EIDR?
TRS3232EIDR supports data rates up to 120kbps, which is sufficient for standard RS-232 serial communication protocols. This makes it compatible with most UART-based microcontrollers and legacy serial devices.
What package does TRS3232EIDR come in and what are its dimensions?
TRS3232EIDR is available in a 16-pin SOIC (Small Outline Integrated Circuit) package, designated by the 'DR' suffix. It is suitable for surface-mount PCB assembly and has a compact footprint ideal for space-constrained designs.
