CD74ACT573E from Texas Instruments, in a PDIP-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 | Active-low output enable; HIGH puts the 3-state outputs in high impedance, and latch operation is independent of it. |
| 2 | D0 | input | Data input 0 to the transparent latch. |
| 3 | D1 | input | Data input 1 to the transparent latch. |
| 4 | D2 | input | Data input 2 to the transparent latch. |
| 5 | D3 | input | Data input 3 to the transparent latch. |
| 6 | D4 | input | Data input 4 to the transparent latch. |
| 7 | D5 | input | Data input 5 to the transparent latch. |
| 8 | D6 | input | Data input 6 to the transparent latch. |
| 9 | D7 | input | Data input 7 to the transparent latch. |
| 10 | GND | power_in | Ground; supply return, with all voltages referenced to ground. |
| 11 | LE | input | Latch enable; outputs follow inputs when HIGH and data is latched when it goes LOW. |
| 12 | Q7 | tri_state | Non-inverting 3-state latch output 7 with ±24 mA drive. |
| 13 | Q6 | tri_state | Non-inverting 3-state latch output 6 with ±24 mA drive. |
| 14 | Q5 | tri_state | Non-inverting 3-state latch output 5 with ±24 mA drive. |
| 15 | Q4 | tri_state | Non-inverting 3-state latch output 4 with ±24 mA drive. |
| 16 | Q3 | tri_state | Non-inverting 3-state latch output 3 with ±24 mA drive. |
| 17 | Q2 | tri_state | Non-inverting 3-state latch output 2 with ±24 mA drive. |
| 18 | Q1 | tri_state | Non-inverting 3-state latch output 1 with ±24 mA drive. |
| 19 | Q0 | tri_state | Non-inverting 3-state latch output 0 with ±24 mA drive. |
| 20 | VCC | power_in | Positive supply; 4.5 V to 5.5 V recommended for ACT types, absolute maximum -0.5 to 6 V. |
