| 3 | 2A | input | Data input of inverter 2 (2Y = NOT 2A); input has internal clamp diodes, and input clamp current is limited to ±20 mA for VI < -0.5 V or VI > VCC+0.5 V. |
| 4 | 2Y | output | Inverted data output of inverter 2; output current is limited to ±25 mA for -0.5 V < VO < VCC+0.5 V. |
| 5 | 3A | input | Data input of inverter 3 (3Y = NOT 3A); input has internal clamp diodes, and input clamp current is limited to ±20 mA for VI < -0.5 V or VI > VCC+0.5 V. |
| 6 | 3Y | output | Inverted data output of inverter 3; output current is limited to ±25 mA for -0.5 V < VO < VCC+0.5 V. |
| 7 | GND | power_in | Ground reference (0 V) for the device. |
| 8 | 4Y | output | Inverted data output of inverter 4; output current is limited to ±25 mA for -0.5 V < VO < VCC+0.5 V. |
| 9 | 4A | input | Data input of inverter 4 (4Y = NOT 4A); input has internal clamp diodes, and input clamp current is limited to ±20 mA for VI < -0.5 V or VI > VCC+0.5 V. |
| 10 | 5Y | output | Inverted data output of inverter 5; output current is limited to ±25 mA for -0.5 V < VO < VCC+0.5 V. |
| 11 | 5A | input | Data input of inverter 5 (5Y = NOT 5A); input has internal clamp diodes, and input clamp current is limited to ±20 mA for VI < -0.5 V or VI > VCC+0.5 V. |
| 12 | 6Y | output | Inverted data output of inverter 6; output current is limited to ±25 mA for -0.5 V < VO < VCC+0.5 V. |
| 13 | 6A | input | Data input of inverter 6 (6Y = NOT 6A); input has internal clamp diodes, and input clamp current is limited to ±20 mA for VI < -0.5 V or VI > VCC+0.5 V. |
| 14 | VCC | power_in | Supply voltage: 2.0 V to 6.0 V recommended for SN74HC04 and 4.5 V to 5.5 V for SN74HCT04, with absolute maximum rating of -0.5 V to +7 V. |
