The C945 is an age old Japanese Bipolar audio frequency NPN transistor 60V 150mA TO-92 package. It has a decent gain value (hfe) of maximum 700 and is highly linear. Hence it was widely used in amplifier.
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 BS170 is an N−Channel enhancement mode field effect transistors are produced using ON Semiconductor proprietary, high cell density, DMOS technology.
The Bipolar Power Transistor is designed for use in general-purpose amplifier and switching applications. The MJE2955T (PNP) and MJE3055T (NPN) are complementary devices.
The ADC0820CCN is 8-bit MOS A/D Converter offers a 1.5μs conversion time while dissipating a maximum 75mW of power. The half-flash technique consists of 31comparators, a most significant 4-bit ADC and a least significant 4-Bit ADC.
