The CD4049BM and CD4050BM devices are inverting and noninverting hex buffers, and feature logic-level conversion using only one supply voltage (VCC) Inverting Hex Buffer IC SOP-16 Pins Package.
The BC856 3B is a transistors are designed for general purpose amplifier applications. They are housed in the SC−70/SOT−323 which is designed for low power surface mount applications.
The 2SC2553 is a Material of Transistor-Si Polarity: NPN Maximum Collector Power Dissipation 40W Maximum Collector-Base Voltage 500V Maximum Collector-Emitter Voltage 400V Maximum Emitter-Base Voltage 7V Maximum Collector Current 5A Max.
The CD4001BM, HEF4001BT, and MC14001D are NOR gates provide the system designer with direct implementation of the NOR function and supplement the existing family of CMOS gates. All inputs and outputs are buffered IC SOP-14 Pins Package.
