SN74LVC1G374DCKR from Texas Instruments, in a SC-70-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CLK | input | Clock input. Positive edge transfers the logic level present at D to output Q. VIH = 0.65×VCC (1.65-1.95 V) up to 0.7×VCC (4.5-5.5 V); inputs accept up to 5.5 V regardless of VCC. |
| 2 | GND | power_in | Ground reference (0 V) for supply and logic signals. |
| 3 | D | input | Data input to the D-type flip-flop. Level present at D on the rising edge of CLK is transferred to Q. Accepts inputs up to 5.5 V (down-translation to VCC supported). |
| 4 | Q | tri_state | 3-state data output. Drives the stored flip-flop level when OE is low; goes to high-impedance when OE is high. IOH/IOL = ±24 mA at VCC = 3 V (±32 mA at 4.5 V). |
| 5 | VCC | power_in | Supply voltage input, 1.65 V to 5.5 V operating range (1.5 V min for data retention only). ICC ≤ 10 µA. Bypass with a local 0.1 µF ceramic capacitor to GND. |
| 6 | OE | input | Active-low output enable. When low, Q drives the stored flip-flop state; when high, Q is placed in high-impedance. OE does not affect the internal flip-flop; data can still be clocked in while Q is Hi-Z. Tie to VCC via a pull-up to guarantee Hi-Z during power-up/power-down. |
