Texas Instruments · Latches · SSOP-20-208mil
SN74HC573ADBR from Texas Instruments, in a SSOP-20-208mil. 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; low enables tri-state drivers, high disables to high impedance |
| 2 | 1D | input | Data input for bit 1, sampled when LE is high |
| 3 | 2D | input | Data input for bit 2, sampled when LE is high |
| 4 | 3D | input | Data input for bit 3, sampled when LE is high |
| 5 | 4D | input | Data input for bit 4, sampled when LE is high |
| 6 | 5D | input | Data input for bit 5, sampled when LE is high |
| 7 | 6D | input | Data input for bit 6, sampled when LE is high |
| 8 | 7D | input | Data input for bit 7, sampled when LE is high |
| 9 | 8D | input | Data input for bit 8, sampled when LE is high |
| 10 | GND | power_in | Ground connection |
| 11 | LE | input | Latch Enable input; outputs transparent when high, data latched when low |
| 12 | 8Q | tri_state | Output bit 8, tri-state controlled by OE |
| 13 | 7Q | tri_state | Output bit 7, tri-state controlled by OE |
| 14 | 6Q | tri_state | Output bit 6, tri-state controlled by OE |
| 15 | 5Q | tri_state | Output bit 5, tri-state controlled by OE |
| 16 | 4Q | tri_state | Output bit 4, tri-state controlled by OE |
| 17 | 3Q | tri_state | Output bit 3, tri-state controlled by OE |
| 18 | 2Q | tri_state | Output bit 2, tri-state controlled by OE |
| 19 | 1Q | tri_state | Output bit 1, tri-state controlled by OE |
| 20 | VCC | power_out | Power supply voltage, 2V to 6V range |
