IC 7406 Hex Inverter Buffer/Driver

Description

The 74×06 (ex 74LS06) is a chip with six open-collector inverters that has a maximum output voltage of 30V and a sink current of 40 mA so that they can interface with high-level circuits (such as MOSFETs), or for driving high-current loads. When you have an open collector output, it means it’s easy to connect it to other chips that use different logic levels. However, it also means you can’t just swap it out with a regular inverter chip. In this guide, you will learn everything you need to know about this chip and how to use inverters in your projects. Package and pinout for 74×06 What does the 74HC06 / 74LS06 do? The 74×06 gives you six open collector inverters that you can use individually. An inverter (or NOT gate) is a logic gate that outputs the opposite of the input. In the truth table below, you can see what the output will be for any given input: Truth table for the NOT gate (inverter) How To Use This Chip The 74LS06 comes in a 14-pin package, and you need to connect it to power before you can use it. Most 7400 ICs support a VCC voltage of 5V. One difference between the HC and LS versions of the chip is that the 74HC06 supports 2V to 6V, while the 74LS06 only supports 5V. 74×06 Pinout The 74×06 has 14 pins and contains six open-collector inverters, each with a maximum output voltage of 30V. Its pins are laid out as shown in the pinout diagram below: Pin # Type Description 1 Input Input to the first NOT gate. 2 Output Open-collector output from the first NOT gate. 3 Input Input to the second NOT gate. 4 Output Open-collector output from the second NOT gate. 5 Input Input to the third NOT gate. 6 Output Open-collector output from the third NOT gate. 7 Power Connect to ground (GND). 8 Output Open-collector output from the fourth NOT gate. 9 Input Input to the fourth NOT gate. 10 Output Open-collector output from the fifth NOT gate. 11 Input Input to the fifth NOT gate. 12 Output Open-collector output from the sixth NOT gate. 13 Input Input to the sixth NOT gate. 14 Power Positive power supply (VCC).
