XBLW · Latches · SOIC-20-208mil
SN74HC373NSDTR from XBLW, in a SOIC-20-208mil. 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 | Active-LOW 3-state output enable input; a HIGH on OE causes all outputs to assume a high-impedance OFF-state regardless of LE or D inputs. |
| 2 | Q0 | tri_state | 3-state latch output for bit 0; transparent to D0 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 3 | D0 | input | Data input for latch 0; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 4 | D1 | input | Data input for latch 1; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 5 | Q1 | tri_state | 3-state latch output for bit 1; transparent to D1 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 6 | Q2 | tri_state | 3-state latch output for bit 2; transparent to D2 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 7 | D2 | input | Data input for latch 2; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 8 | D3 | input | Data input for latch 3; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 9 | Q3 | tri_state | 3-state latch output for bit 3; transparent to D3 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 10 | GND | power_in | Ground supply reference, 0V. |
| 11 | LE | input | Active-HIGH latch enable input; when HIGH, latches are transparent and outputs follow D inputs; when LOW, data present at the inputs a set-up time before the HIGH-to-LOW transition is stored. |
| 12 | Q4 | tri_state | 3-state latch output for bit 4; transparent to D4 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 13 | D4 | input | Data input for latch 4; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 14 | D5 | input | Data input for latch 5; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 15 | Q5 | tri_state | 3-state latch output for bit 5; transparent to D5 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 16 | Q6 | tri_state | 3-state latch output for bit 6; transparent to D6 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 17 | D6 | input | Data input for latch 6; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 18 | D7 | input | Data input for latch 7; entered into latch when LE is HIGH; stored at the HIGH-to-LOW transition of LE. |
| 19 | Q7 | tri_state | 3-state latch output for bit 7; transparent to D7 when LE is HIGH and OE is LOW; latches data when LE goes LOW; high-impedance when OE is HIGH. |
| 20 | VCC | power_in | Positive supply voltage, recommended operating range 2.0V to 6.0V, absolute maximum −0.5V to +7.0V. |
