*Notice: Stresses above those listed under "Maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

The Microchip Technology Inc. 24AA174 is a cascadable 16K bit Electrically Erasable PROM. The device 24AA174 is organized as eight blocks of 256 x 8-bit memory with a 2-wire serial interface and provides a specially addressed OTP (one-time programmable) 16 byte security block. Low voltage design permits operation down to 1.8 volts (end-of-life voltage for most popular battery technologies) with standby and active currents of only 5 µA and 1 mA respectively. The 24AA174 also has a page-write capability for up to 16 bytes of data.

The 24AA174 is available in the standard 8-pin DIP and 8-lead surface mount SOIC packages. The three select pins, A0, A1, and A2, function as chip select inputs and allow up to eight devices to share a common bus, for up to 128K bits total system EEPROM.
