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. |
