CD4013 - Dual D Flip Flop. The CD4013 dual D flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors. Each flip-flop has independent data, set, reset, and clock inputs and ``Q'' and ``Q'' outputs. These devices can be used for shift register applications, and by connecting ``Q'' output to the data input, for counter and toggle applications. The logic level present at the ``D'' input is transferred to the Q output during the positive-going transition of the clock pulse. Setting or resetting is independent of the clock and is accomplished by a high level on the set or reset line respectively. Features
Wide supply voltage range: 3.0V to 15V
High noise immunity: 0.45 VDD (typ.)
Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS
Applications: Automotive, Alarm system, Data terminals, Industrial electronics, Instrumentation, Remote metering, Medical electronics, Computers etc.

CD4028 - BCD-to-Decimal Decoder. The CD4028 is a BCD-to-decimal or binary-to-octal decoder consisting of 4 inputs, decoding logic gates and 10 output buffers. ABCD code applied to the 4 inputs, A, B, C, and D, results in a high level at the selected 1 to1 0 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A, B, and C is decoded in octal at outputs 0–7. A high level signal at the D input inhibits octal decoding and causes outputs 0–7 to go LOW. Features:
Wide supply voltage range: 3.0V to 15V
High noise immunity: 0.45 VDD (typ.)
Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS
Glitch free outputs
“Positive logic” on inputs and outputs
Applications: Code conversion, Address decoding, Indicator-tube decoder
