Most 7400 ICs support a VCC voltage of 5V. One difference between the HC and LS versions of the chip is that the 74HC09 supports 2V to 6V, while the 74LS09 supports only 5V. Once it has power connected, you can use any of the four AND gates inside. The 74HC09/74LS09 IC connected to power This chip has open collector outputs. That means you can only sink current, not source it. Each gate output of the 74HC09 can sink about 4 mA when powered with 5V. While the 74LS09 can usually sink about 8 mA of current. These values can vary between manufacturers of the chip though. Applications: General-purpose digital logic circuits . Microprocessor interfacing and signal conditioning. Timing circuits and pulse generation . Switching applications for logic control. Datasheet: SN74LS09N
