WitrynaThe HEF4002B is a dual 4-input NOR gate. The outputs are fully buffered for highest noise immunity and pattern insensitivity to output impedance variations.. It operates over a recommended V DD power supply range of 3 V to 15 V referenced to V SS (usually ground). Unused inputs must be connected to V DD, V SS, or another input. Witryna19 gru 2024 · You need to describe the characteristics at the iPod output (possibly 16 to 64 Ohms) and the input of the amp (perhaps 600 to 10000 Ohms) to be able to match the pot at that location. I would look at a 1kOhm pot for testing and do further measurements and research if planning for production.
