SN74HC373PW from lingxingic, in a TSSOP-20. 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 | OE, | input | Three-state output enable input; active low enables outputs, active high places outputs in high-impedance state |
| 2 | Q0 | tri_state | Three-state latch output for data bit 0 |
| 3 | D0 | input | Data input for bit 0; latched on LE falling edge |
| 4 | D1 | input | Data input for bit 1; latched on LE falling edge |
| 5 | Q1 | tri_state | Three-state latch output for data bit 1 |
| 6 | Q2 | tri_state | Three-state latch output for data bit 2 |
| 7 | D2 | input | Data input for bit 2; latched on LE falling edge |
| 8 | D3 | input | Data input for bit 3; latched on LE falling edge |
| 9 | Q3 | tri_state | Three-state latch output for data bit 3 |
| 10 | GND | power_in | Ground connection; zero voltage reference point |
| 11 | LE | input | Latch enable input; active high makes latch transparent (outputs follow inputs), active low latches data |
| 12 | Q4 | tri_state | Three-state latch output for data bit 4 |
| 13 | D4 | input | Data input for bit 4; latched on LE falling edge |
| 14 | D5 | input | Data input for bit 5; latched on LE falling edge |
| 15 | Q5 | tri_state | Three-state latch output for data bit 5 |
| 16 | Q6 | tri_state | Three-state latch output for data bit 6 |
| 17 | D6 | input | Data input for bit 6; latched on LE falling edge |
| 18 | D7 | input | Data input for bit 7; latched on LE falling edge |
| 19 | Q7 | tri_state | Three-state latch output for data bit 7 |
| 20 | VCC | power_in | Supply voltage; positive power supply connection |
