ICs & Dips

The 74HC4024 is a 7-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and seven fully buffered parallel outputs (Q0 to Q6). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

74HC4040 is a 16 Pin 12-Stage Binary Ripple Counter IC having 2V to 6V Operating Voltage range with 1uA low input current. It has a clock input (CP), 

The 74HC4040 is identical in pin out to the standard CMOS MC14040. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of 12 master?slave flip?flops. The output of each flip?flop feeds the next and the frequency at each output is half of that of the preceding one. The state counter advances on the negative?going edge of the Clock input. Reset is asynchronous and active?high. State changes of the Q outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and may have to be gated with the Clock of the HC4040A for some designs.

The 74HC4049 is a high-speed Si-gate CMOS device and is pin compatible with the ?4049? of the ?4000B? series. It is specified in compliance with JEDEC standard no. 7A.The 74HC4049 provides six inverting buffers with a modified input protection structure, which has no diode connected to VCC. Input voltages of up to 15 V may therefore be used. This feature enables the inverting buffers to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example 15 V logic (?4000B series?) can be converted down to 2 V logic. The actual input switch level remains related to the VCC and is the same as mentioned in the family characteristics .At the same time each part can be used as a simple inverter without level translation

The 74HC4060 is a 14-stage ripple-carry counter/divider and oscillator with three oscillator terminals (RS, RTC and CTC), ten buffered parallel outputs (Q3 to Q9 and Q11 to Q13) and an overriding asynchronous master reset (MR). The oscillator configuration allows design of either RC or crystal oscillator circuits. The oscillator may be replaced by an external clock signal at input RS. In this case, keep the oscillator pins (RTC and CTC) floating. The counter advances on the HIGH-to-LOW transition of RS. A HIGH level on MR clears all counter stages and forces all outputs LOW, independent of the other input conditions. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 

74HC4066 Quadruple Bilateral Analog Switch IC (744066) DIP-14 Package

The 74HC4066; 74HCT4066 is a quad single pole, single throw analog switch. Each switch features two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When nE is LOW, the analog switch is turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
