This device is capable of both random and sequential
reads. Reads may be sequential within address
boundaries 0000h to FFFFh and 10000h to 1FFFFh.
Functional address lines allow up to four devices on the
same data bus. This allows for up to 4 Mbits total
system EEPROM memory. This device is available in
the standard 8-pin PDIP, SOIC and SOIJ packages.
Note 1: 100 kHz for VCC < 2.5V
2: 100 kHz for VCC < 4.5V (E-temp)
3: 400 kHz for VCC < 2.5V
