GN Semic · Latches · SOP-20
GN573D from GN Semic, in a SOP-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 | Tri-state output enable input (active low); high level places all outputs in high-impedance state. |
| 2 | D0 | input | Data input for bit 0 of the 8-bit latch. |
| 3 | D1 | input | Data input for bit 1 of the 8-bit latch. |
| 4 | D2 | input | Data input for bit 2 of the 8-bit latch. |
| 5 | D3 | input | Data input for bit 3 of the 8-bit latch. |
| 6 | D4 | input | Data input for bit 4 of the 8-bit latch. |
| 7 | D5 | input | Data input for bit 5 of the 8-bit latch. |
| 8 | D6 | input | Data input for bit 6 of the 8-bit latch. |
| 9 | D7 | input | Data input for bit 7 of the 8-bit latch. |
| 10 | GND | power_in | Ground reference (0V). |
| 11 | LE | input | Latch enable input (active high); high level enables transparent mode where outputs follow inputs, low level latches data at setup time before LE falling edge. |
| 12 | Q7 | tri_state | Tri-state latch output for bit 7 driven by D7; controlled by OE signal. |
| 13 | Q6 | tri_state | Tri-state latch output for bit 6 driven by D6; controlled by OE signal. |
| 14 | Q5 | tri_state | Tri-state latch output for bit 5 driven by D5; controlled by OE signal. |
| 15 | Q4 | tri_state | Tri-state latch output for bit 4 driven by D4; controlled by OE signal. |
| 16 | Q3 | tri_state | Tri-state latch output for bit 3 driven by D3; controlled by OE signal. |
| 17 | Q2 | tri_state | Tri-state latch output for bit 2 driven by D2; controlled by OE signal. |
| 18 | Q1 | tri_state | Tri-state latch output for bit 1 driven by D1; controlled by OE signal. |
| 19 | Q0 | tri_state | Tri-state latch output for bit 0 driven by D0; controlled by OE signal. |
| 20 | VCC | power_in | Supply voltage with recommended operating range 2.0V to 6.0V. |

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)
