AZ75232GTR-G1 from Diodes Incorporated, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Positive supply voltage for driver. Recommended operating range 7.5 V to 15 V; absolute max 15 V.
2	RA1	input	Receiver 1 input. Accepts EIA/TIA-232-F level input (-30 V to +30 V absolute max), converts to TTL/CMOS output at RY1.
3	RA2	input	Receiver 2 input. Accepts EIA/TIA-232-F level input, converts to TTL/CMOS output at RY2.
4	RA3	input	Receiver 3 input. Accepts EIA/TIA-232-F level input, converts to TTL/CMOS output at RY3.
5	DY1	output	Driver 1 output. EIA/TIA-232-F level output (-15 V to +15 V range) driven from TTL/CMOS input at DA1.
6	DY2	output	Driver 2 output. EIA/TIA-232-F level output driven from TTL/CMOS input at DA2.
7	RA4	input	Receiver 4 input. Accepts EIA/TIA-232-F level input, converts to TTL/CMOS output at RY4.
8	DY3	output	Driver 3 output. EIA/TIA-232-F level output driven from TTL/CMOS input at DA3.
9	RA5	input	Receiver 5 input. Accepts EIA/TIA-232-F level input, converts to TTL/CMOS output at RY5.
10	VSS	power_in	Negative supply voltage for driver. Recommended operating range -15 V to -7.5 V; absolute max -15 V.
11	GND	power_in	Ground reference (0 V) for the device.
12	RY5	output	Receiver 5 output. TTL/CMOS level output derived from EIA/TIA-232-F input at RA5.
13	DA3	input	Driver 3 input. TTL/CMOS input (VIH >= 1.9 V, VIL <= 0.8 V) drives EIA/TIA-232-F output at DY3.
14	RY4	output	Receiver 4 output. TTL/CMOS level output derived from EIA/TIA-232-F input at RA4.
15	DA2	input	Driver 2 input. TTL/CMOS input drives EIA/TIA-232-F output at DY2.
16	DA1	input	Driver 1 input. TTL/CMOS input drives EIA/TIA-232-F output at DY1.
17	RY3	output	Receiver 3 output. TTL/CMOS level output derived from EIA/TIA-232-F input at RA3.
18	RY2	output	Receiver 2 output. TTL/CMOS level output derived from EIA/TIA-232-F input at RA2.
19	RY1	output	Receiver 1 output. TTL/CMOS level output derived from EIA/TIA-232-F input at RA1.
20	VCC	power_in	Supply voltage for receiver. Recommended operating range 4.5 V to 5.5 V; absolute max 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`az75232gtr-g1.step`	267 KB	You want the bare part, or you mark your own boards.
`az75232gtr-g1-etched.step`	3.0 MB	You want the part with `AZ75232GTR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 750 faces against 327 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
