Texas Instruments · Flip Flops · VSSOP-8-0.5mm
SN74AUC1G74DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | CLK | input | Clock input; data at D is transferred to the outputs on the positive-going edge when PRE and CLR are inactive (high), and inputs are 3.6-V tolerant. |
| 2 | D | input | Data input; data meeting the setup time is transferred to the outputs on the rising clock edge, and it can be changed after the hold-time interval. |
| 3 | Q̅ | output | Complementary flip-flop output with ±8-mA drive at 1.8 V, set low by PRE low and high by CLR low. |
| 4 | GND | power_in | Ground; continuous current through VCC or GND is limited to ±100 mA. |
| 5 | Q | output | True flip-flop output with ±8-mA drive at 1.8 V, set high by PRE low and low by CLR low. |
| 6 | CLR | input | Active-low asynchronous clear that resets Q low regardless of other inputs and overrides PRE when both are low. |
| 7 | PRE | input | Active-low asynchronous preset that sets Q high regardless of the levels of the other inputs. |
| 8 | VCC | power_in | Supply voltage, operational at 0.8 V to 2.7 V and designed for 1.65 V to 1.95 V, with 10 µA max ICC. |
