i can't find 24LS256 EEPROM datasheet

[karthigowri]

hi everybody ,i need help to find 24LS256 EEPROM datasheet.

i already search in google but there is no datasheet in that name.the google only shows 24LC256 IC's datasheet.but i need 24LS256.

anybody help me.:?::?::?:

Are you sure 24LS256?
Not 24LC256?

What manufacturer? What package?. What marking?

I also have never heard of 24LS256 but maybe it's a code used by some small fabrication company. I would guess it would be the same specificaton as 24LC256 which is commonly available.

Are you sure it's an EEPROM? There is a 74LS256 but that's a TTL latch device.

THats just an antique LS TTL version of the now CMOS version 24LC256

24LS meant LS memory in the 80's and I guess mine is still working.

It should be 24LC256 and not 24LS256. From where you have find the part number?

Interesting, I actually have a few of these in the parts bin. I always thought they were cheap Chinese knockoffs with a slight misspelling. I still occasionally see large lots of the 24LS256 offered for sale on the wholesale Chinese semiconductor marketplaces.

Good guess

I think an 'LS' (= bipolar Low power Shottky) version of such a dense memory is unlikely but smaller manufacturers often change the letters to 'customize' a standard part so it sound like their proprietary design. I would guess the 'LC' data sheet covered this device.

LS256 was it obsolete before the internet was invented?

Use the C256 specs unless you are looking for burn specs. Then consult burner OEM for updates ($)

or assume compatible on I2C
