Maxim Integrated offer the industry's broadest selection of low-on-resistance, high-performance analog switches and multiplexers. Maxim analog products are design for general-purpose use as well as specific applications. Maxim analog switches and multiplexers are offered for operation from 1.6V to 80V.
The Maxim IC DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The Maxim IC DS1307 RTC transfers address and data serially through an I²C, bidirectional bus. The clock/calendar on the DS1307
provides seconds, minutes, hours, day, date, month, and year
information. The end of the month date is automatically adjusted for
months with fewer than 31 days, including corrections for leap year. The
clock on the Maxim IC RTC operates in either the 24-hour or 12-hour format with AM/PM indicator. The DS1307
has a built-in power-sense circuit that detects power failures and
automatically switches to the backup supply. Timekeeping operation
continues while the part operates from the backup supply.
