Product details

Package and field-swap reality

The DS1087LU-21H+ comes in an 8-pin uMAX/uSOP (3.00 mm body width), which is the same footprint as an 8-pin MSOP or TSSOP. It is surface-mount only — no socket option. On a service call, swapping this means hot air or a preheater; it is not a DIP you lever out with a screwdriver. The part marking is small but legible under a loupe. Orientation is standard: pin 1 marked by a dot or chamfer on the package top. If you are stocking a field-repair kit, keep a few in a tape strip or cut-tape sleeve; they are small enough to lose in a toolbag pocket.

Frequently asked questions

What is the maximum frequency of DS1087LU-21H+?

The maximum output frequency is 16 MHz. This is the hard ceiling — the part cannot generate frequencies above that.

What supply voltage does DS1087LU-21H+ require?

It operates from 2.7V to 3.6V. The 3.3V rail is the typical use case, but it will also run on a 2.7V or 3.0V supply if your board uses those.

Is DS1087LU-21H+ RoHS compliant?

Yes, it is ROHS3 compliant, covering all six original RoHS substances plus the four phthalates. No special handling documentation is needed for EU shipments.

What package is DS1087LU-21H+ available in?

It is offered in an 8-pin uMAX/uSOP package (3.00 mm body width), which is footprint-compatible with 8-pin MSOP and TSSOP. The supplier device package is 8-uMAX/uSOP.
