SN74HC241DWR

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

SN74HC241DWR 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 Active-low output enable for buffers 1A1-1A4; outputs 1Y1-1Y4 are passed when low and high-impedance when high.
2 1A1 input Buffer 1 data input A1, passed noninverted to 1Y1 when 1OE is low.
3 2Y4 tri_state Buffer 2 output Y4, noninverted from 2A4 when 2OE is high and high-impedance when 2OE is low.
4 1A2 input Buffer 1 data input A2, passed noninverted to 1Y2 when 1OE is low.
5 2Y3 tri_state Buffer 2 output Y3, noninverted from 2A3 when 2OE is high and high-impedance when 2OE is low.
6 1A3 input Buffer 1 data input A3, passed noninverted to 1Y3 when 1OE is low.
7 2Y2 tri_state Buffer 2 output Y2, noninverted from 2A2 when 2OE is high and high-impedance when 2OE is low.
8 1A4 input Buffer 1 data input A4, passed noninverted to 1Y4 when 1OE is low.
9 2Y1 tri_state Buffer 2 output Y1, noninverted from 2A1 when 2OE is high and high-impedance when 2OE is low.
10 GND power_in Ground reference for the device.
11 2A1 input Buffer 2 data input A1, passed noninverted to 2Y1 when 2OE is high.
12 1Y4 tri_state Buffer 1 output Y4, noninverted from 1A4 when 1OE is low and high-impedance when 1OE is high.
13 2A2 input Buffer 2 data input A2, passed noninverted to 2Y2 when 2OE is high.
14 1Y3 tri_state Buffer 1 output Y3, noninverted from 1A3 when 1OE is low and high-impedance when 1OE is high.
15 2A3 input Buffer 2 data input A3, passed noninverted to 2Y3 when 2OE is high.
16 1Y2 tri_state Buffer 1 output Y2, noninverted from 1A2 when 1OE is low and high-impedance when 1OE is high.
17 2A4 input Buffer 2 data input A4, passed noninverted to 2Y4 when 2OE is high.
18 1Y1 tri_state Buffer 1 output Y1, noninverted from 1A1 when 1OE is low and high-impedance when 1OE is high.
19 2OE input Active-high output enable for buffers 2A1-2A4; outputs 2Y1-2Y4 are passed when high and high-impedance when low.
20 VCC power_in Supply voltage, 2 V to 6 V recommended, with a 0.1-µF bypass capacitor recommended close to the pin.
