CD4502 Hex Inverter/Buffer with 3-State Outputs DIP-16 (CD4502 DIP IC)
The CD4502 is a high-voltage CMOS integrated circuit that contains six independent inverting buffers with 3-state outputs. It features a common Output Enable (OE) and a common Inhibit (INH) control, allowing the outputs to be placed in a high-impedance state or forced to a low level regardless of the data inputs.
This IC is primarily used in bus-oriented digital systems where multiple devices need to share a common data line without interference. It is a staple in Arduino electronics projects in India for controlling data flow between microcontrollers and peripheral memory or for level shifting in mixed-voltage circuits.
