About this product
The 74HC20 is a CMOS logic IC with two independent 4-input NAND gates. An output goes low only when all four of its inputs are high, which makes it useful for combining several control signals, simple address decoding and general digital logic. Its inputs include clamp diodes, so a current-limiting resistor can be used when an input is driven above VCC.

Frequently asked questions
What is the price of 74HC20 Dual 4-Input NAND Gate IC in Egypt?
74HC20 Dual 4-Input NAND Gate IC currently costs between 21.9 and 27 EGP across 2 offers in Egypt.
Where can I buy 74HC20 Dual 4-Input NAND Gate IC in Egypt?
74HC20 Dual 4-Input NAND Gate IC is available from Most Electronics and Circuits Electronics. Compare the offers above to find the best price.
Can I power the 74HC20 from a 5 V Arduino supply?
Yes. The 74HC series operates from 2 V to 6 V, so a 5 V supply is within range. Connect VCC to 5 V and GND to ground, and place a decoupling capacitor close to the supply pins.
What should I do with unused inputs?
Do not leave them floating. For a NAND gate, tie an unused input to VCC so it does not affect the output, or to GND if you intend to hold the gate output high.
