MAX3160EEAP+T from Analog Devices Inc Maxim Integrated, in a SSOP-20-208mil. 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 C1+ passive Positive terminal of the positive charge-pump flying capacitor (C1).
2 VCC power_in Positive supply voltage, specified for +3.0V to +5.5V operation with absolute maximum VCC to GND of -0.3V to +6V.
3 C1- passive Negative terminal of the positive charge-pump flying capacitor (C1).
4 GND power_in Ground reference for the device.
5 Z(B)/T1OUT bidirectional RS-232 driver output T1OUT in RS-232 mode; inverting RS-485/RS-422 driver output Z(B) in full-duplex mode and inverting receiver input B in half-duplex mode.
6 Y(A)/T2OUT bidirectional RS-232 driver output T2OUT in RS-232 mode; noninverting RS-485/RS-422 driver output Y(A) in full-duplex mode and noninverting receiver input A in half-duplex mode.
7 R1OUT output RS-232 receiver output; inverting, and it remains active in shutdown.
8 RO/R2OUT output RS-485/RS-422 receiver output RO in RS-485 mode; RS-232 receiver output R2OUT in RS-232 mode.
9 SHDN input Active-low shutdown control; driving SHDN low shuts down the transmitters and charge pump and reduces supply current to 10nA.
10 FAST input Transmitter speed-select input; logic-low selects slew-rate limiting, and asserting FAST allows RS-232 data rates up to 1Mbps and RS-485/RS-422 data rates up to 10Mbps.
11 RS-485/RS-232 input Mode-select input; logic-high selects RS-485/RS-422 operation and logic-low selects RS-232 operation.
12 HDPLX input Duplex-select input; logic-low selects full-duplex operation and logic-high selects half-duplex operation for RS-485/RS-422.
13 A/R2IN input Noninverting RS-485/RS-422 receiver input A in RS-485 mode; RS-232 receiver input R2IN in RS-232 mode, with inputs rated to ±25V to GND.
14 B/R1IN input Inverting RS-485/RS-422 receiver input B in RS-485 mode; RS-232 receiver input R1IN in RS-232 mode, with inputs rated to ±25V to GND.
15 DE485/T2IN input RS-485/RS-422 driver enable DE485 in RS-485 mode; RS-232 driver input T2IN in RS-232 mode.
16 DI/T1IN input RS-485/RS-422 driver input DI in RS-485 mode; RS-232 driver input T1IN in RS-232 mode.
17 V- power_out Negative charge-pump rail generated by the inverting charge pump at -5.5V (nominal).
18 C2- passive Negative terminal of the negative charge-pump flying capacitor (C2).
19 C2+ passive Positive terminal of the negative charge-pump flying capacitor (C2).
20 V+ power_out Positive charge-pump rail generated by the doubling charge pump at +5.5V (nominal).
