SN74ACT374PWR

Texas Instruments · Flip Flops · TSSOP-20

SN74ACT374PWR 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 Output Enable input, active low; when low Q outputs are active, when high outputs are high-impedance
2 1Q tri_state 3-state Q output of flip-flop 1; high-impedance when OE is high
3 1D input D input of flip-flop 1, sampled on positive clock edge
4 2D input D input of flip-flop 2, sampled on positive clock edge
5 2Q tri_state 3-state Q output of flip-flop 2; high-impedance when OE is high
6 3Q tri_state 3-state Q output of flip-flop 3; high-impedance when OE is high
7 3D input D input of flip-flop 3, sampled on positive clock edge
8 4D input D input of flip-flop 4, sampled on positive clock edge
9 4Q tri_state 3-state Q output of flip-flop 4; high-impedance when OE is high
10 GND power_in Ground
11 CLK input Clock input, positive edge-triggered; triggers capture of D input levels to Q outputs
12 5Q tri_state 3-state Q output of flip-flop 5; high-impedance when OE is high
13 5D input D input of flip-flop 5, sampled on positive clock edge
14 6D input D input of flip-flop 6, sampled on positive clock edge
15 6Q tri_state 3-state Q output of flip-flop 6; high-impedance when OE is high
16 7Q tri_state 3-state Q output of flip-flop 7; high-impedance when OE is high
17 7D input D input of flip-flop 7, sampled on positive clock edge
18 8D input D input of flip-flop 8, sampled on positive clock edge
19 8Q tri_state 3-state Q output of flip-flop 8; high-impedance when OE is high
20 VCC power_out Power supply; 4.5 V to 5.5 V
