Nexperia · Latches · SOIC-20-300mil

74HCT373D from Nexperia, 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 (active LOW); a HIGH level puts the outputs in the high-impedance OFF-state without affecting the latches.
2 Q0 tri_state 3-state latch output 0.
3 D0 input Data input 0.
4 D1 input Data input 1.
5 Q1 tri_state 3-state latch output 1.
6 Q2 tri_state 3-state latch output 2.
7 D2 input Data input 2.
8 D3 input Data input 3.
9 Q3 tri_state 3-state latch output 3.
10 GND power_in Ground (0 V).
11 LE input Latch enable input (active HIGH); latches are transparent when HIGH and store data when LOW.
12 Q4 tri_state 3-state latch output 4.
13 D4 input Data input 4.
14 D5 input Data input 5.
15 Q5 tri_state 3-state latch output 5.
16 Q6 tri_state 3-state latch output 6.
17 D6 input Data input 6.
18 D7 input Data input 7.
19 Q7 tri_state 3-state latch output 7.
20 VCC power_in Supply voltage; 4.5 V to 5.5 V recommended for 74HCT373.
