The DS1743-100+ from Analog Devices / Maxim Integrated is a Y2K-compliant, nonvolatile timekeeping RAM. This integrated circuit combines NV SRAM, a Real-Time Clock, crystal, power-fail control circuit, and a lithium energy source.
Key electrical specifications include an operating voltage range of 4.5V to 5.5V and a typical current consumption of 3mA at 5V. The device offers 8KB of memory and utilizes a parallel interface for data access. Clock registers are accessed identically to the static RAM, residing in the top eight RAM locations.
This component features automatic leap year compensation valid through 2099, a century byte register, and power-fail write protection. It also includes a low-battery voltage level indicator flag. The lithium energy source is disconnected until power is applied for the first time, preserving its freshness.
Packaged in a 28-EDIP module, the DS1743-100+ is designed for through-hole mounting. Its operating temperature range is 0°C to 70°C. This device is pin-for-pin compatible with other densities of DS174XP timekeeping RAMs.
The operating voltage range is 4.5V to 5.5V.
