Pinout
The MAX3221EUE+T comes in a 16-pin TSSOP (Thin Shrink Small Outline Package) package. Here are some key functions of the pins:
1. VCC: Power supply.
2. GND: Ground connection.
3. TXD: Transmit data input; accepts logic-level signals.
4. RXD: Receive data output; outputs RS-232 level signals.
5. C1+, C1-, C2+, C2-: Capacitor connections for the charge pump, which generates the necessary RS-232 voltage levels.
6. V+ and V-: Generated positive and negative voltages for RS-232 signaling.
7. EN: Enable input; controls the operation of the transceiver.
8. SHDN: Shutdown control; reduces power consumption.
9. INVALID: Indicates the validity of the receiver signal.
This IC is used for reliable serial communication, typically requiring minimal external components due to its integrated charge pump.
