74CBTLV3244PW from Nexperia, in a TSSOP-20. 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 1OE input Output enable input (active LOW) for switches 1A1 to 1B4; the switches are disabled (high-impedance) when this input is HIGH.
2 1A1 bidirectional Data input/output (A port) of the 1A1 switch channel; ON-state resistance is about 5 Ω and rail-to-rail switching is supported when enabled.
3 2B4 bidirectional Data input/output (B port) of the 2B4 switch channel; the channel is disabled when 2OE is HIGH.
4 1A2 bidirectional Data input/output (A port) of the 1A2 switch channel; the channel is disabled when 1OE is HIGH.
5 2B3 bidirectional Data input/output (B port) of the 2B3 switch channel; the channel is disabled when 2OE is HIGH.
6 1A3 bidirectional Data input/output (A port) of the 1A3 switch channel; the channel is disabled when 1OE is HIGH.
7 2B2 bidirectional Data input/output (B port) of the 2B2 switch channel; the channel is disabled when 2OE is HIGH.
8 1A4 bidirectional Data input/output (A port) of the 1A4 switch channel; the channel is disabled when 1OE is HIGH.
9 2B1 bidirectional Data input/output (B port) of the 2B1 switch channel; the channel is disabled when 2OE is HIGH.
10 GND power_in Ground (0 V); all voltages are referenced to this pin.
11 2A1 bidirectional Data input/output (A port) of the 2A1 switch channel; the channel is disabled when 2OE is HIGH.
12 1B4 bidirectional Data input/output (B port) of the 1B4 switch channel; the channel is disabled when 1OE is HIGH.
13 2A2 bidirectional Data input/output (A port) of the 2A2 switch channel; the channel is disabled when 2OE is HIGH.
14 1B3 bidirectional Data input/output (B port) of the 1B3 switch channel; the channel is disabled when 1OE is HIGH.
15 2A3 bidirectional Data input/output (A port) of the 2A3 switch channel; the channel is disabled when 2OE is HIGH.
16 1B2 bidirectional Data input/output (B port) of the 1B2 switch channel; the channel is disabled when 1OE is HIGH.
17 2A4 bidirectional Data input/output (A port) of the 2A4 switch channel; the channel is disabled when 2OE is HIGH.
18 1B1 bidirectional Data input/output (B port) of the 1B1 switch channel; the channel is disabled when 1OE is HIGH.
19 2OE input Output enable input (active LOW) for switches 2A1 to 2B4; the switches are disabled (high-impedance) when this input is HIGH.
20 VCC power_in Positive supply voltage; recommended operating range is 2.3 V to 3.6 V.
