EEPROM ARRAY  
(8 x 256 x 8)  
The Microchip Technology Inc. 24LC174 is a cascad-  
able 16K bit Electrically Erasable PROM. The device 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 2.5 volts with standby and active currents of  
only 5 µA and 1 mA respectively. The 24LC174 also  
has a page-write capability for up to 16 bytes of data.  
The 24LC174 is available in the standard 8-pin DIP and  
8-lead surface mount SOIC packages.
