HGSEMI · Flip Flops · SOP-20

Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE | input | Active-LOW output enable input; a HIGH level forces Q0 to Q7 into the high-impedance OFF-state without changing the flip-flop contents. |
| 2 | Q0 | output | Non-inverting 3-state data output of flip-flop 0, high-impedance when OE is HIGH. |
| 3 | D0 | input | Data input to flip-flop 0, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 4 | D1 | input | Data input to flip-flop 1, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 5 | Q1 | output | Non-inverting 3-state data output of flip-flop 1, high-impedance when OE is HIGH. |
| 6 | Q2 | output | Non-inverting 3-state data output of flip-flop 2, high-impedance when OE is HIGH. |
| 7 | D2 | input | Data input to flip-flop 2, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 8 | D3 | input | Data input to flip-flop 3, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 9 | Q3 | output | Non-inverting 3-state data output of flip-flop 3, high-impedance when OE is HIGH. |
| 10 | GND | power_in | Ground reference, 0 V. |
| 11 | CP | input | Clock input; flip-flops capture their D inputs on the LOW-to-HIGH edge. |
| 12 | Q4 | output | Non-inverting 3-state data output of flip-flop 4, high-impedance when OE is HIGH. |
| 13 | D4 | input | Data input to flip-flop 4, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 14 | D5 | input | Data input to flip-flop 5, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 15 | Q5 | output | Non-inverting 3-state data output of flip-flop 5, high-impedance when OE is HIGH. |
| 16 | Q6 | output | Non-inverting 3-state data output of flip-flop 6, high-impedance when OE is HIGH. |
| 17 | D6 | input | Data input to flip-flop 6, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 18 | D7 | input | Data input to flip-flop 7, stored on the LOW-to-HIGH clock transition if set-up and hold times are met; inputs include clamp diodes for use with current-limiting resistors above VCC. |
| 19 | Q7 | output | Non-inverting 3-state data output of flip-flop 7, high-impedance when OE is HIGH. |
| 20 | VCC | power_in | Supply voltage: 2.0 V to 6.0 V for 74HC374 and 4.5 V to 5.5 V for 74HCT374 (absolute maximum 7.0 V). |

Package_SO:SOP-20_7.5x12.8mm_P1.27mm - 3D model: SOP-20, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
