The 74HC4060 is a high speed binary ripple carry counter. These counters are implemented utilizing advanced silicon-gate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS. The 74HC4060 is a 14-stage counter, which device increments on the falling edge (negative transition) of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input. The 74HC4060 also has two additional inputs to enable easy connection of either an RC or crystal oscillator. This device is pin equivalent to the CD4060. All inputs are protected from damage due to static discharge by protection diodes to VCC and ground.

74HC390 is a 16 Pin Dual 4-bit Decade Ripple Counter IC having 2V to 6V Operating Voltage range. It has been divided into four separately clocked sections. The counters have two divide-by-2 sections and two divide-by-5 sections. These sections share an asynchronous master reset input (nMR) and can be used in a BCD decade or bi-quinary configuration. If master reset inputs 1MR and 2MR are used to clear all 8 bits of the counter simultaneously, numerous counting configurations are possible within one package. Section clocks nCP0 and nCP1, allow ripple counter or frequency division applications of divide-by-2, 4, 5, 10, 20, 25, 50 or 100. The HIGH-to-LOW transition of the clock inputs nCP0 and nCP1 trigger each section. For BCD decade operation, the nQ0 output is connected to the nCP1 input of the divide-by-5 section. For bi-quinary decade operation, the nQ3 output is connected to the nCP0 input and nQ0 becomes the decade output. A HIGH on the nMR input overrides the clocks and sets the four outputs LOW. Inputs include clamp diodes. It enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

74HC30 is a 14 Pin 8-input NAND Gate IC having 2V to 6V Operating Voltage with output current as 5.2mA.  It's input contains clamp diodes which enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

74HC221 is a 16 Pin Hex D-type Flip-Flop with Reset IC having 2V to 6V Operating Voltage range with 5.2mA output current and 1uA low input current. It utilize  advanced  silicon-gate  CMOS  technology. They feature speeds comparable to low power Schottky  TTL  circuitry  while  retaining  the  low  power  and  high noise immunity characteristic of CMOS circuits. Each multivibrator features both a negative, A, and a positive,  B,  transition  triggered  input,  either  of  which  can  be used as an inhibit input. Also included is a clear input that when  taken  low  resets  the  one  shot.  The  74HC221 can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH.
