MAX3227ECUE+

Maxim Integrated · Pre-ordered Chips · TSSOP-16

MAX3227ECUE+ from Maxim Integrated, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 READY output Active-high ready-to-transmit output that goes high when V- falls below -4V and the device is ready to transmit.
2 C1+ passive Positive terminal of the voltage-doubler charge-pump capacitor.
3 V+ power_out +5.5V supply generated by the charge pump.
4 C1- passive Negative terminal of the voltage-doubler charge-pump capacitor.
5 C2+ passive Positive terminal of the inverting charge-pump capacitor.
6 C2- passive Negative terminal of the inverting charge-pump capacitor.
7 V- power_out -5.5V supply generated by the charge pump.
8 R1IN input RS-232 receiver input, protected to ±15kV ESD.
9 R1OUT output TTL/CMOS receiver output.
10 INVALID output Valid signal detector output, active low; a logic high indicates a valid RS-232 level is present on a receiver input.
11 T1IN input TTL/CMOS transmitter input with no pullup resistor; connect unused inputs to GND or VCC.
12 FORCEON input Active-high force-on input; drive high to override AutoShutdown Plus, keeping transmitters and receivers on (FORCEOFF must be high).
13 T1OUT output RS-232 transmitter output, protected to ±15kV ESD.
14 GND power_in Ground.
15 VCC power_in +3.0V to +5.5V single supply voltage.
16 FORCEOFF input Active-low force-off input; when low, transmitters are high impedance, charge pumps are shut down and receivers are active, overriding AutoShutdown Plus and FORCEON.
