About this product
The 74266 is a 74-series TTL integrated circuit with four independent 2-input Exclusive-NOR (XNOR) gates in a 14-pin DIP package. Each gate outputs logic 1 when its two inputs are equal, which suits bit comparison, equality detection and parity-style logic. Its outputs are open-collector, so an external pull-up resistor is needed to read a high level.

Frequently asked questions
What is the price of 74266 Quad 2-Input Exclusive-NOR (XNOR) Gate IC DIP-14 in Egypt?
74266 Quad 2-Input Exclusive-NOR (XNOR) Gate IC DIP-14 currently costs between 25 and 31 EGP across 3 offers in Egypt.
Where can I buy 74266 Quad 2-Input Exclusive-NOR (XNOR) Gate IC DIP-14 in Egypt?
74266 Quad 2-Input Exclusive-NOR (XNOR) Gate IC DIP-14 is available from Microohm, Makers Electronics, and Circuits Electronics. Compare the offers above to find the best price.
Do I need a pull-up resistor on the 74266 outputs?
Yes. The 74266 has open-collector outputs, so each output needs an external pull-up resistor to the supply to produce a high level. Typical values are in the 1k to 10k ohm range; check the datasheet for the value recommended for your design.
What should I do with unused gate inputs?
Do not leave inputs floating. Tie unused inputs to a defined logic level, either to Vcc or to ground as shown in the datasheet, to avoid noise-induced false outputs.
