ICL3232 in RS-232 Transceivers Family
The ICL3232 is a family of high-performance RS-232 transceivers manufactured by Renesas Electronics Corporation. Designed for serial communication, these devices operate from a single +3.0V to +5.5V supply and feature two receivers and two transmitters. They utilize an internal charge pump with four small external capacitors to generate necessary voltage levels, making them ideal for space-constrained designs that require legacy serial connectivity while maintaining modern low-voltage power rails for improved energy efficiency and simplified power architecture.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Package | Receiver Hysteresis | Temp Range | Stock |
|---|---|---|---|---|
| ICL3232CPZ (Renesas Electronics Corporation) | DIP-16 | 300 mV | 0degC ~ 70degC | 5,603 |
| ICL3232EIBNZ (Renesas Electronics Corporation) | SOIC-16 | 500 mV | -40degC ~ 85degC | 2,709 |
| ICL3232CBNZ (Renesas Electronics Corporation) | SOIC-16 | 300 mV | 0degC ~ 70degC | 1,396 |
| ICL3232CVZ (Renesas Electronics Corporation) | TSSOP-16 | 300 mV | 0degC ~ 70degC | 1,439 |
Variants within the ICL3232 sub-family primarily differ based on their thermal ratings and physical package options. For example, the ICL3232CVZ is housed in a thin 16-TSSOP package suitable for high-density boards, while the ICL3232CBNZ comes in a standard 16-SOIC package for easier prototyping and assembly. Some variants are also specified for extended industrial temperature ranges (-40C to +85C) versus standard commercial ranges.
