Texas Instruments · Latches · SOIC-20-300mil
CD74HCT573M96 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 | Active-low output enable; high places the eight Q outputs in the high-impedance state without affecting the latches, and should be tied to VCC through a pullup resistor during power up or down. |
| 2 | 1D | input | Data input 1 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 3 | 2D | input | Data input 2 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 4 | 3D | input | Data input 3 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 5 | 4D | input | Data input 4 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 6 | 5D | input | Data input 5 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 7 | 6D | input | Data input 6 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 8 | 7D | input | Data input 7 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 9 | 8D | input | Data input 8 (TTL-compatible, VIH min 2 V, VIL max 0.8 V); Q follows D while LE is high. |
| 10 | GND | power_in | Ground reference; continuous current through VCC or GND is limited to ±50 mA. |
| 11 | LE | input | Latch enable; Q outputs follow D when high and are latched at the D logic levels when low. |
| 12 | 8Q | tri_state | Three-state latch output 8, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 13 | 7Q | tri_state | Three-state latch output 7, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 14 | 6Q | tri_state | Three-state latch output 6, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 15 | 5Q | tri_state | Three-state latch output 5, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 16 | 4Q | tri_state | Three-state latch output 4, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 17 | 3Q | tri_state | Three-state latch output 3, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 18 | 2Q | tri_state | Three-state latch output 2, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 19 | 1Q | tri_state | Three-state latch output 1, high-impedance when OE is high, with ±25 mA maximum continuous output current. |
| 20 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended (absolute maximum 7 V), with a 0.1-µF bypass capacitor recommended close to the pin. |
