onsemi · Buffer/Driver/Transceiver · SOIC-20-300mil

MC74AC573DWR2G 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 OE input 3-state output enable input; LOW enables the outputs, HIGH puts them in high impedance without affecting latch data entry.
2 D0 input Data input 0, enters the latch when LE is HIGH.
3 D1 input Data input 1, enters the latch when LE is HIGH.
4 D2 input Data input 2, enters the latch when LE is HIGH.
5 D3 input Data input 3, enters the latch when LE is HIGH.
6 D4 input Data input 4, enters the latch when LE is HIGH.
7 D5 input Data input 5, enters the latch when LE is HIGH.
8 D6 input Data input 6, enters the latch when LE is HIGH.
9 D7 input Data input 7, enters the latch when LE is HIGH.
10 GND power_in Ground reference for supply and all voltages.
11 LE input Latch enable input; HIGH makes latches transparent, LOW stores the data present at the HIGH-to-LOW transition.
12 O7 tri_state 3-state latch output 7, sources/sinks 24 mA.
13 O6 tri_state 3-state latch output 6, sources/sinks 24 mA.
14 O5 tri_state 3-state latch output 5, sources/sinks 24 mA.
15 O4 tri_state 3-state latch output 4, sources/sinks 24 mA.
16 O3 tri_state 3-state latch output 3, sources/sinks 24 mA.
17 O2 tri_state 3-state latch output 2, sources/sinks 24 mA.
18 O1 tri_state 3-state latch output 1, sources/sinks 24 mA.
19 O0 tri_state 3-state latch output 0, sources/sinks 24 mA.
20 VCC power_in Positive supply; 2.0 to 6.0 V for AC, 4.5 to 5.5 V for ACT (absolute maximum 7.0 V).
