SN74AC241DWR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-20-300mil

SN74AC241DWR from Texas Instruments, in a SOIC-20-300mil. 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 1 (active low); when 1OE is high the 1Y outputs are placed in the high-impedance state, and when it is low the 1Y outputs pass the 1A data.
2 1A1 input Data input 1A1 for the 1Y1 buffer, passed noninverted to 1Y1 when 1OE is low.
3 2Y4 output Output 2Y4 of the second buffer section, which goes high impedance when 2OE is low; continuous output current is limited to ±50 mA.
4 1A2 input Data input 1A2 for the 1Y2 buffer, passed noninverted to 1Y2 when 1OE is low.
5 2Y3 output Output 2Y3 of the second buffer section, which goes high impedance when 2OE is low.
6 1A3 input Data input 1A3 for the 1Y3 buffer, passed noninverted to 1Y3 when 1OE is low.
7 2Y2 output Output 2Y2 of the second buffer section, which goes high impedance when 2OE is low.
8 1A4 input Data input 1A4 for the 1Y4 buffer, passed noninverted to 1Y4 when 1OE is low.
9 2Y1 output Output 2Y1 of the second buffer section, which goes high impedance when 2OE is low.
10 GND power_in Ground reference pin; continuous current through VCC or GND is limited to ±200 mA.
11 2A1 input Data input 2A1 for the 2Y1 buffer, passed noninverted to 2Y1 when 2OE is high.
12 1Y4 output Output 1Y4 of the first buffer section, which goes high impedance when 1OE is high.
13 2A2 input Data input 2A2 for the 2Y2 buffer, passed noninverted to 2Y2 when 2OE is high.
14 1Y3 output Output 1Y3 of the first buffer section, which goes high impedance when 1OE is high.
15 2A3 input Data input 2A3 for the 2Y3 buffer, passed noninverted to 2Y3 when 2OE is high.
16 1Y2 output Output 1Y2 of the first buffer section, which goes high impedance when 1OE is high.
17 2A4 input Data input 2A4 for the 2Y4 buffer, passed noninverted to 2Y4 when 2OE is high.
18 1Y1 output Output 1Y1 of the first buffer section, which goes high impedance when 1OE is high.
19 2OE input Output enable 2 (active high); when 2OE is low the 2Y outputs are placed in the high-impedance state.
20 VCC power_in Supply pin; the recommended supply range is 2 V to 6 V.
