Description

Programmable Read-Only Memory (EEPROM) organized as 16,384 words of eight bits

each. The device’s cascading feature allows up to eight devices to share a common

2-wire bus. The device is optimized for use in many industrial and commercial

applications where low-power and low-voltage operation are essential. The devices are

available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN,

8-pad XDFN, and 8-ball VFBGA packages. In addition, this device operates from

1.7V to 5.5V.
