This is a +5V-powered multichannel RS-232 driver/receiver IC in a 20-pin DIP. It belongs to the MAX220–MAX249 family, which uses integrated charge-pump circuitry to produce RS-232 levels from a single +5V supply, so no separate ±12V supply is needed. The family is intended for EIA/TIA-232E and V.28/V.24 interfaces.
Key Features
- Single +5V supply operation
- Integrated charge pump removes the need for a ±12V supply
- For EIA/TIA-232E and V.28/V.24 interfaces
- 5 µW shutdown mode (family feature)
- 20-pin DIP

Frequently Asked Questions
Which exact part number is this?
The listing gives only the family (MAX220–MAX249). Confirm the exact part with the store before designing in.
Why no ±12V supply?
A charge pump inside the chip generates the higher RS-232 voltages from the +5V supply.
