IC NE 555 timer:
The NE555 is an integrated circuit that capable of producing accurate timing pulses. This IC is used as a multivibrater. By using this IC we can construct two types of multivibrater, monostable and astable. The monostable multivibrater produces a single pulse when a triggering pulse is applied to its triggering input. The astable multivibrater produces a train of pulses depending on the Resister-Capacitor combination wired around it.
With a monostable operation, the time delay is controlled by one external resistor and one capacitor connected between Vcc-Discharge (R), and Threshold-Ground (C). With an astable operation, the frequency and pulse width are produced by two external resistors and one capacitor connected between Vcc-Discharge (R), Discharge-Threshold (R), and Threshold-Ground (C).
74154 4-16 line decoder/demultiplexer:
IC 74154 is a 4-16 line decoder, it takes the 4 line BCD input and selects respective output one among the 16 output lines. It is active low output IC so when any output line is selected it is indicated by active low signal, rest of the output lines will remain active high. This 4-line-to-16-line decoder utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs, G1 and G2, are low. The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low. When either strobe input is high, all outputs are high. These demultiplexer are ideally suited for implementing high-performance memory decoders.
All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.
Truth Table:
74126 Tri – State Buffer
This IC is a tri state buffer contains four independent gates each of which performs a non-inverting buffer function. The outputs have the 3-STATE feature. When control signal is at high state, the outputs are nothing but the data present at its input terminals. When control signal is at low state, the outputs are held at high impedance state. So no output will be available at the output terminal.
IC 7474 D-flip-flop
IC 7474 is a conventional D-flip-flop IC. This IC consists of two D flip-flops. These flip-flops are used to latch the data that present at its input terminal. Each flip-flop has one data, one clock, one clear, one preset input terminals.
Seven Segment Decoder:
The DM74LS47 accepts four lines of BCD (8421) input data, generates their complements internally and decodes the data with seven AND/OR gates having open-collector outputs to drive indicator segments directly. Each segment output is guaranteed to sink 24mA in the ON (LOW) state and withstand 15V in the OFF (HIGH) state with a maximum leakage current of 250 mA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression functions.
