Manufactured by National Semiconductor - DIP14 package
These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages.
Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

I will combine postage where several different items are purchased at the same time. I only charge one single postage charge, that of the most expensive shipping rate, and will then include all other items for that single rate. Most items are small and attract just a basic shipping charge to cover post & packaging but some heavier items may be charged at a higher rate.
If you purchase more than one product please add it to your basket (if possible) and then request a total for your combined purchases. (I believe this only works on ebay.co.uk desktop website and not on mobile devices or some other country websites). I will then send you a total with just the one postage charge. If you cannot follow this process then I will refund the excess postage when I process the order.
In most cases you can order as many of a single item as you want for the same postage as buying one, and combine other items within this single charge. For some heavier items such as transformers, there may be an additional postage charge for the second and subsequent items. Please feel free to contact us if you have any queries
