Product details

Temperature grade and environment

Rated 0°C to 70°C commercial temperature range. This part belongs in indoor, climate-controlled equipment — office automation, point-of-sale terminals, instrumentation racks. Not suited for outdoor telecom cabinets or unheated enclosures without additional thermal management.

Package and mounting

24-pin EDIP (0.600 inch, 15.24 mm pitch), through-hole mount. The module footprint is larger than a surface-mount SOIC or TSSOP, so board area is a consideration. The through-hole package simplifies hand-assembly and rework — a plus for prototype runs or field repair.

Lifecycle and sourcing posture

The part is ROHS3 compliant.

Frequently asked questions

What battery voltage does the DS1687-5+ support?

The battery backup input accepts 2.5V to 3.7V, which covers standard 3V lithium coin cells.

Can the DS1687-5+ operate at 3.3V?

No — the main supply range is 4.5V to 5.5V. 3.3V operation is outside the rated supply range.

What is the difference between DS1687-5 and DS1687-5+?

The DS1687-5+ is the ROHS3-compliant version of the DS1687-5. Electrical specifications and pinout are identical; the '+' suffix indicates lead-free / RoHS compliance.
