The DS1742W-150+ is a full-function, year 2000-compliant real-time clock/calendar (RTC) and 2k x 8 nonvolatile static RAM from Analog Devices / Maxim Integrated. 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. The RTC information includes century, year, month, date, day, hours, minutes, and seconds in 24-hour BCD format, with automatic leap year compensation valid up to the year 2100. The device offers quartz accuracy of ±1 minute a month at +25°C and includes a battery voltage level indicator flag.
Designed for through-hole mounting, the DS1742W-150+ comes in a 24-EDIP package. It operates over a voltage range of 2.97V to 3.63V with a typical current consumption of 2mA at 3.3V. The part also features power-fail write protection, allowing for ±10% VCC power supply tolerance, and is totally nonvolatile with over 10 years of operation in the absence of power.
The operating voltage for the DS1742W-150+ is between 2.97V and 3.63V.
The DS1742W-150+ operates within a temperature range of 0°C to 70°C.
