    Hi Everyone,

    I m using EEPROM At28C64B ,It has output enable Pin which is active low
    ,I m using nand gate to trigger the output enable pin by giving it a low logic at the output of nand gate & it will trigger the output enable pin which is active low,as well as i have to use a pull down resistor with the nand gate output ,what value of resistor should i use for this purpose to pull down.

    thanks.

    What NAND gate are you using that has an open-collector or open-drain output?

    Actually, I should've said open emitter or open source. :rolleyes:
