BC558 Transistor (Pack of 5) The BC558 is a PNP transistor and a heavy-duty drop-in replacement for a 2N2222 or 2N3906. The three terminals of a bipolar transistor are called the emitter, base, and collector. A small current into the base controls a large current flow from the collector to the emitter. The current at the base is typically one-hundredth of the collector-emitter current. Moreover, the large current flow is almost independent of the voltage across the transistor from collector to emitter. This makes it possible to obtain a large amplification of voltage by taking the output voltage from a resistor in series with the collector. read our blog explaining the BC547 Transistor : Basic Knowledge, Pin Configuration & Features.

Binary Up/Down Counter with Clear IC - 74HC193 The 74HC Series 74HC193 is a UP/DOWN DIP-16 Binary Counter. Separate Count Up and Count Down Clocks are used and in either counting mode, the circuits operate synchronously. The outputs change state synchronously with the LOW-to-HIGH transitions on the clock inputs. Separate Terminal Count Up and Terminal Count Down outputs are provided which are used as the clocks for a subsequent stage without extra logic, thus simplifying multistage counter designs. Individual preset inputs allow the circuits to be used as programmable counters. Both the Parallel Load (PL) and the Master Reset (MR) inputs asynchronously override the clocks. check out : Presettable synchronous BCD decade counter IC - 74HC160 Pinout: Pinout Of 74HC193 IC Applications: Counters check out : Decade Up/Down Counter with Clear IC - 74HC192
