provide timer and counter functions. Function blocks allow inputs from the left and pass power through to the right when the function is done or when various conditions are met. Either the timer has timed out or the counter has counted to the preset. Function block usage differs from manufacturer to manufacturer. DATASHEET The ICM7555 and ICM7556 are CMOS RC timers providing significantly improved performance over the standard SE/NE 555/556 and 355 timers, while at the same time being direct replacements for those devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low Threshold, Trigger and Low-power single CMOS timer Datasheet -production data Features • Very low power consumption: – 110 µA typ at VCC = 5 V – 90 µa typ at VCC = 3 V • High maximum astable frequency of 2.7 MHz • Pin-to-pin functionally-compatible with bipolar NE555(a) • Wide voltage range: +2 V to +16 V • Supply current spikes reduced during output ...

datasheet on the following pages is a relatively good datasheet. It tries to concisely tell you everything you need to know about the device, a common 555 timer chip (the duct-tape of the electronics hobbyist). Most datasheets for ICs follow the same general layout. You don’t have to understand everything in a datasheet. There’s a lot of Before listing the top ten electronics mini projects using IC 555 we would like to clear some point like operating voltage, temperature, applications etc. of timer IC.

The front end features a programmable oscillator which is simi- lar to the 555 timer. The output drivers feature a high pulse current buffer stage and an internal deadtime designed for minimum driver cross-conduction. Propa- gation delays for the two channels are matched to sim- plify use in 50% duty cycle applications.

Design Hint; The incoming trigger signal does not have to be a digital signal, or a signal generated by a CMOS or TTL series logic family. Other than the type of transistors used the block diagram shown in Figure 1 is basically the same as a conventional 555. This particular oscillator depends on the pin 7 transistor, much like the 555 Monostable Multivibrator shown in an earlier experiment.

Charles Platt in Make: Electronics has a great reaction timer that uses all three 555 modes (pg 170). One 555 is set up with a start switch as a one-shot to provide a delay to start the circuit. (Looking back at the schematic for the one-shot, R4 charges C2, which is what gives us our delay. How to use the 555 timer as a Monostable Multivibrator SCHEMATIC DIAGRAM ILLUSTRATION INSTRUCTIONS This is one of the most basic 555 circuits. This circuit is part of this chips datasheet, complete with the math needed to design to specification, and is one of the reasons a 555 is referred to as a timer. The internal block diagram and schematic of the 555 timer are highlighted with the same color across all three drawings to clarify how the chip is implemented: Green: Between the positive supply voltage V CC and the ground GND is a voltage divider consisting of three identical resistors , which create two reference voltages at 1 ⁄ 3 V CC and 2 ⁄ 3 V CC . 555 Timer Pin Diagram and Descriptions. Now as shown in figure, there are eight pins for a 555 Timer IC namely, 1.Ground. 2.Trigger. 3.Output. 4.Reset. 5.Control. 6.Threshold. 7.Discharge. 8.Power or Vcc Pin 1.
