face. Low-current design permits operation with typical

standby and active currents of only 1 ? A and 1 mA,

respectively. The device has a page write capability for

up to 16 bytes of data. Functional address lines allow

Features:

? Single-Supply with Operation down to 1.7V

? Low-Power CMOS Technology:

- 1 mA active current, typical

- 1 ? A standby current, typical at 5.5V

the connection of up to eight 24AA014/24LC014

devices on the same bus for up to 8 Kbits of contiguous

EEPROM memory. The device is available in the

standard 8-pin PDIP, 8-pin SOIC (150 mil), TSSOP, 2x3

DFN and TDFN and MSOP packages. The 24AA014/

24LC014 is also available in the 6-lead SOT-23

package.
