CD74ACT240M96

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

CD74ACT240M96 from Texas Instruments, in a SOIC-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 Bank 1 output enable, active low; when high, outputs 1Y0 to 1Y3 are forced to high impedance (Z).
2 1A0 input Bank 1 channel 1 data input to the buffer.
3 2Y3 output Bank 2 channel 4 3-state buffer output.
4 1A1 input Bank 1 channel 2 data input to the buffer.
5 2Y2 output Bank 2 channel 3 3-state buffer output.
6 1A2 input Bank 1 channel 3 data input to the buffer.
7 2Y1 output Bank 2 channel 2 3-state buffer output.
8 1A3 input Bank 1 channel 4 data input to the buffer.
9 2Y0 output Bank 2 channel 1 3-state buffer output.
10 GND power_in Ground reference for the device; all voltages are referenced to ground.
11 2A0 input Bank 2 channel 1 data input to the buffer.
12 1Y3 output Bank 1 channel 4 3-state buffer output.
13 2A1 input Bank 2 channel 2 data input to the buffer.
14 1Y2 output Bank 1 channel 3 3-state buffer output.
15 2A2 input Bank 2 channel 3 data input to the buffer.
16 1Y1 output Bank 1 channel 2 3-state buffer output.
17 2A3 input Bank 2 channel 4 data input to the buffer.
18 1Y0 output Bank 1 channel 1 3-state buffer output.
19 2OE input Bank 2 output enable, active low; when high, outputs 2Y0 to 2Y3 are forced to high impedance (Z).
20 VCC power_in Positive supply; ACT types are specified for 4.5 V to 5.5 V operation (Section 4.2).
