Cypress CY7C168A-25PC 4Kx4 RAM DIL20
Manufactured by Cypress - DIL20 through hole package
Description
The CY7C168A is a high-performance CMOS static RAM organized as 4096 by 4 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE) and three-state drivers. The CY7C168A has an automatic power-down feature, reducing the power consumption by 77% when deselected. Writing to the device is accomplished when the Chip Select (CE) and Write Enable (WE) inputs are both LOW. Data on the four data input/output pins (I/O0 through I/O3) is written into the memory location specified on the address pins (A0 through A11). Reading the device is accomplished by taking the Chip Enable (CE) LOW, while Write Enable (WE) remains HIGH. Under these conditions, the contents of the location specified on the address pins will appear on the four data input/output pins (I/O0 through I/O3). The input/output pins remain in a high-impedance state when Chip Enable (CE) is HIGH or Write Enable (WE) is LOW

Combined Postage
I will combine postage where several different items are purchased at the same time.
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
International Postage
Standard AirMail is NOT tracked - If you want your package tracked the option is available at checkout by selecting the appropriate postage option.
We are usually happy to ship items throughout Europe and N America.
Orders placed by 1pm Mon - Fri will usually be shipped the same day but this is not guaranteed.
