74LVC241AT20-13 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 1OE input Active-low output enable for buffer bank 1 (1Y1..1Y4). When low, 1An data passes to 1Yn; when high, 1Y outputs are in high-impedance state. Schmitt-trigger input, 5.5V tolerant.
2 1A1 input Data input to buffer 1, channel 1. Drives output 1Y1 when 1OE is low. Schmitt-trigger input, 5.5V tolerant.
3 2Y4 tri_state Data output from buffer 2, channel 4. Non-inverting driver output for 2A4, high-Z when 2OE is low. Rated for ±24 mA at VCC = 3V.
4 1A2 input Data input to buffer 1, channel 2. Drives output 1Y2 when 1OE is low. Schmitt-trigger input, 5.5V tolerant.
5 2Y3 tri_state Data output from buffer 2, channel 3. Non-inverting driver output for 2A3, high-Z when 2OE is low. Rated for ±24 mA at VCC = 3V.
6 1A3 input Data input to buffer 1, channel 3. Drives output 1Y3 when 1OE is low. Schmitt-trigger input, 5.5V tolerant.
7 2Y2 tri_state Data output from buffer 2, channel 2. Non-inverting driver output for 2A2, high-Z when 2OE is low. Rated for ±24 mA at VCC = 3V.
8 1A4 input Data input to buffer 1, channel 4. Drives output 1Y4 when 1OE is low. Schmitt-trigger input, 5.5V tolerant.
9 2Y1 tri_state Data output from buffer 2, channel 1. Non-inverting driver output for 2A1, high-Z when 2OE is low. Rated for ±24 mA at VCC = 3V.
10 GND power_in Ground reference (0 V). Continuous current through GND rated up to -100 mA.
11 2A1 input Data input to buffer 2, channel 1. Drives output 2Y1 when 2OE is high. Schmitt-trigger input, 5.5V tolerant.
12 1Y4 tri_state Data output from buffer 1, channel 4. Non-inverting driver output for 1A4, high-Z when 1OE is high. Rated for ±24 mA at VCC = 3V.
13 2A2 input Data input to buffer 2, channel 2. Drives output 2Y2 when 2OE is high. Schmitt-trigger input, 5.5V tolerant.
14 1Y3 tri_state Data output from buffer 1, channel 3. Non-inverting driver output for 1A3, high-Z when 1OE is high. Rated for ±24 mA at VCC = 3V.
15 2A3 input Data input to buffer 2, channel 3. Drives output 2Y3 when 2OE is high. Schmitt-trigger input, 5.5V tolerant.
16 1Y2 tri_state Data output from buffer 1, channel 2. Non-inverting driver output for 1A2, high-Z when 1OE is high. Rated for ±24 mA at VCC = 3V.
17 2A4 input Data input to buffer 2, channel 4. Drives output 2Y4 when 2OE is high. Schmitt-trigger input, 5.5V tolerant.
18 1Y1 tri_state Data output from buffer 1, channel 1. Non-inverting driver output for 1A1, high-Z when 1OE is high. Rated for ±24 mA at VCC = 3V.
19 2OE input Active-high output enable for buffer bank 2 (2Y1..2Y4). When high, 2An data passes to 2Yn; when low, 2Y outputs are in high-impedance state. Schmitt-trigger input, 5.5V tolerant.
20 VCC power_in Positive supply, 1.65V to 3.6V operating (1.5V minimum for data retention only). Absolute maximum -0.5V to +7.0V.
