CD74HCT373M96 from Texas Instruments, in a SOIC-20-300mil. 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 | Buffered output-enable input that places the eight outputs in a normal logic state (low) or the high-impedance state (high), without affecting the latches' internal operation. |
| 2 | 1Q | tri_state | Channel 1 latch output that follows 1D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 3 | 1D | input | Channel 1 data input to the transparent D-type latch. |
| 4 | 2D | input | Channel 2 data input to the transparent D-type latch. |
| 5 | 2Q | tri_state | Channel 2 latch output that follows 2D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 6 | 3Q | tri_state | Channel 3 latch output that follows 3D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 7 | 3D | input | Channel 3 data input to the transparent D-type latch. |
| 8 | 4D | input | Channel 4 data input to the transparent D-type latch. |
| 9 | 4Q | tri_state | Channel 4 latch output that follows 4D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 10 | GND | power_in | Ground; continuous current through VCC or GND is limited to ±50 mA. |
| 11 | LE | input | Latch-enable input; Q outputs follow D inputs when high and are latched at the D logic levels when low. |
| 12 | 5Q | tri_state | Channel 5 latch output that follows 5D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 13 | 5D | input | Channel 5 data input to the transparent D-type latch. |
| 14 | 6D | input | Channel 6 data input to the transparent D-type latch. |
| 15 | 6Q | tri_state | Channel 6 latch output that follows 6D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 16 | 7Q | tri_state | Channel 7 latch output that follows 7D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 17 | 7D | input | Channel 7 data input to the transparent D-type latch. |
| 18 | 8D | input | Channel 8 data input to the transparent D-type latch. |
| 19 | 8Q | tri_state | Channel 8 latch output that follows 8D when LE is high, is latched when LE is low, and is high-impedance when OE is high. |
| 20 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended, with a 0.1-μF bypass capacitor placed close to the pin. |
