There are two ways to pull an input LOW with a switch. Here’s dwtasheet series IC data sheet index Here’s a picture of the chip in a circuit board:.

Some manufacturers released some series equivalent CMOS circuits with a 74 prefix, for example the 74HC was a replacement for the with slightly different electrical characteristics different power supply voltage ratings, higher frequency capabilities, lower “on” resistances in analog switches, etc.

PLA 12 inputs, 50 terms, 6 outputs. Pages created and updated by Terry Sturtevant Date Posted: You will need to look at the IC’s datasheet. AND-gated 7xx edge triggered J-K flip-flopasynchronous preset and clear.

See datasheet for an example. If you need to update a browser, you might try Firefox which is free open source available for several platforms Since this page uses cascading style sheets for its layout, it will look best with a browser which supports the specifications as fully as possible.


The following is a list of series digital logic integrated circuits. When the switch is OFF it connects nothingand the input is ‘floating’.

Just treat the switch being closed as a 0. The animation below illustrates both of these.

A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of I added a red line to show how voltage gets from Vcc to the input pin.

This page was last edited on 27 Novemberat Due to the popularity of these parts, other manufacturers have released pin-to-pin compatible devices which kept the sequence number as an aid to identification of compatible parts. Retrieved July 27, Digital electronics Electronic design Electronics lists Integrated circuits.

The lower part numbers were dataheet in the s and s, then higher part numbers were added incrementally over decades.

IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured. If your breadboard is a double length one like shown, remember that typically there is a break in the power rail at the centre point, so it is possible that the GND and VCC are not connected to your NAND.


Note that you will have to use pins from two separate banks on the debugger board. This method has the disadvantage that when the switch is ON it puts 5V across the resistor, which wastes current.

Parts in this section have a pin count of 14 pins or more. How do you know the IC pinout?

These are the power connections: The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. You will find either a circle marking the first pin or a semicircle marking the top of chip. Note that there are 5 parts to the chip “number”:. Archived PDF from the original on July 9, Home Questions Tags Users Unanswered. One way is to connect a pull down resistor from the input to ground. Datassheet is a chart to sumarize the behavior of the circuit I built: You are connecting them to switches so that the inputs are either connected to VCC or left floating.

These parts are prefixed with 54 instead of 74 in the part number.

In a few instances, such as the andthe same suffix in different families do not have completely equivalent logic functions.
