74ACT541SCX

onsemi · Buffers / Drivers · SOIC-20-300mil

74ACT541SCX from onsemi, 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 OE1 input Active-low 3-STATE output enable input 1; outputs are high impedance when OE1 or OE2 is HIGH.
2 I0 input Data input 0, buffered non-inverting to output O0 (ACT541 inputs are TTL-compatible).
3 I1 input Data input 1, buffered non-inverting to output O1 (ACT541 inputs are TTL-compatible).
4 I2 input Data input 2, buffered non-inverting to output O2 (ACT541 inputs are TTL-compatible).
5 I3 input Data input 3, buffered non-inverting to output O3 (ACT541 inputs are TTL-compatible).
6 I4 input Data input 4, buffered non-inverting to output O4 (ACT541 inputs are TTL-compatible).
7 I5 input Data input 5, buffered non-inverting to output O5 (ACT541 inputs are TTL-compatible).
8 I6 input Data input 6, buffered non-inverting to output O6 (ACT541 inputs are TTL-compatible).
9 I7 input Data input 7, buffered non-inverting to output O7 (ACT541 inputs are TTL-compatible).
10 GND power_in Ground reference pin for the device.
11 O7 tri_state 3-STATE data output 7 with 24mA source/sink capability, high impedance when disabled.
12 O6 tri_state 3-STATE data output 6 with 24mA source/sink capability, high impedance when disabled.
13 O5 tri_state 3-STATE data output 5 with 24mA source/sink capability, high impedance when disabled.
14 O4 tri_state 3-STATE data output 4 with 24mA source/sink capability, high impedance when disabled.
15 O3 tri_state 3-STATE data output 3 with 24mA source/sink capability, high impedance when disabled.
16 O2 tri_state 3-STATE data output 2 with 24mA source/sink capability, high impedance when disabled.
17 O1 tri_state 3-STATE data output 1 with 24mA source/sink capability, high impedance when disabled.
18 O0 tri_state 3-STATE data output 0 with 24mA source/sink capability, high impedance when disabled.
19 OE2 input Active-low 3-STATE output enable input 2; outputs are high impedance when OE1 or OE2 is HIGH.
20 VCC power_in Supply voltage pin; ACT devices operate from 4.5V to 5.5V.
