Description
MAX3232ESE+T is a Maxim/Analog Devices RS-232 transceiver pair with two drivers and two receivers. It lets a microcontroller or logic device (TTL/CMOS) talk to RS-232 serial ports.
Key points:
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge pump generates RS-232 voltage swings (no negative rail needed)
- Requires four external charge-pump capacitors (values per datasheet, typically in the 0.1–1 µF range)
- Data rate up to about 250 kbps
- E suffix indicates extended temperature range (-40°C to +85°C); +T indicates Tape & Reel packaging for automated assembly
Common use: connecting MCUs/systems to RS-232 interfaces in embedded and communication devices.
