DS1742W-150 Description

Short technical summary and product information.

The Analog Devices / Maxim Integrated DS1742W-150 is a full-function, year 2000-compliant real-time clock/calendar (RTC) and 2k x 8 nonvolatile static RAM. It features an integrated NV SRAM, real-time clock, crystal, power-fail control circuit, and lithium energy source. The clock registers are accessed identically to the static RAM, residing in the eight top RAM locations. This device supports BCD coded century, year, month, date, day, hours, minutes, and seconds with automatic leap year compensation valid up to the year 2100.

 

Designed for through-hole mounting, the DS1742W-150 operates within a voltage range of 2.97V to 3.63V, typically consuming 2mA at 3.3V. Its operating temperature range is 0°C to 70°C. The package is a 24-EDIP, with a standard package quantity of 24. Key features include leap year support, NVSRAM capability, and Y2K compliance, making it suitable for applications requiring reliable timekeeping and nonvolatile data storage.
