Woooooooow very very good and very good product im so happy and packaging super
I have make a remote control car
Product worked well for my Linux pc, no drivers needed, simple installation.
CD4050 - Hex Non-Inverting Buffer IC
Couldn't load pickup availability
The CD4050 hex buffers IC are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. These devices feature logic-level conversion using only one supply voltage (VDD).
The input signal high level (VIH) can exceed the VDD supply voltage when these devices are used for logic-level conversions. These devices are intended for use as hex buffers IC, CMOS to DTL/ TTL converters, or as CMOS current drivers, and at VDD = 5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range.
