SN74ALVCH374PWR

Texas Instruments · Flip Flops · TSSOP-20

SN74ALVCH374PWR from Texas Instruments, in a TSSOP-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 OE input Buffered output-enable input; low level enables outputs, high level places outputs in high-impedance state.
2 1Q tri_state Q output of flip-flop 1; 3-state output controlled by OE.
3 1D input D data input for flip-flop 1; captured on positive clock transition.
4 2D input D data input for flip-flop 2; captured on positive clock transition.
5 2Q tri_state Q output of flip-flop 2; 3-state output controlled by OE.
6 3Q tri_state Q output of flip-flop 3; 3-state output controlled by OE.
7 3D input D data input for flip-flop 3; captured on positive clock transition.
8 4D input D data input for flip-flop 4; captured on positive clock transition.
9 4Q tri_state Q output of flip-flop 4; 3-state output controlled by OE.
10 GND power_in Ground reference.
11 CLK input Clock input; positive edge-triggered; Q outputs are set to data input logic levels on positive transition.
12 5Q tri_state Q output of flip-flop 5; 3-state output controlled by OE.
13 5D input D data input for flip-flop 5; captured on positive clock transition.
14 6D input D data input for flip-flop 6; captured on positive clock transition.
15 6Q tri_state Q output of flip-flop 6; 3-state output controlled by OE.
16 7Q tri_state Q output of flip-flop 7; 3-state output controlled by OE.
17 7D input D data input for flip-flop 7; captured on positive clock transition.
18 8D input D data input for flip-flop 8; captured on positive clock transition.
19 8Q tri_state Q output of flip-flop 8; 3-state output controlled by OE.
20 VCC power_in Supply voltage input; recommended operating range 1.65 V to 3.6 V.
