SN74ALVCH373DWR

Texas Instruments · Latches · SOIC-20-300mil

SN74ALVCH373DWR 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 OE input Output Enable input (active low); when high, forces all outputs to high-impedance state.
2 1Q tri_state Latch 1 Q output (three-state).
3 1D input Latch 1 data input with bus-hold.
4 2D input Latch 2 data input with bus-hold.
5 2Q tri_state Latch 2 Q output (three-state).
6 3Q tri_state Latch 3 Q output (three-state).
7 3D input Latch 3 data input with bus-hold.
8 4D input Latch 4 data input with bus-hold.
9 4Q tri_state Latch 4 Q output (three-state).
10 GND power_in Ground power return.
11 LE input Latch Enable input (active high); transparent when high, latches when low.
12 5Q tri_state Latch 5 Q output (three-state).
13 5D input Latch 5 data input with bus-hold.
14 6D input Latch 6 data input with bus-hold.
15 6Q tri_state Latch 6 Q output (three-state).
16 7Q tri_state Latch 7 Q output (three-state).
17 7D input Latch 7 data input with bus-hold.
18 8D input Latch 8 data input with bus-hold.
19 8Q tri_state Latch 8 Q output (three-state).
20 VCC power_in Supply voltage (1.65 V to 3.6 V).
