Sunrise set to ship fastest gate arrays yet
Dedicated NEC distributor Sunrise Electronics is now helping customers to design with the latest 0.25-micron CMOS-10HD family of CMOS gate array products.
Both the new couplers offer a minimum common mode transient immunity (CM) of 10kV/us and typical values of 20kV/us.
The PS9114 features an open collector output, allowing flexible circuit design.
The PS9115 has totempole output, offering shorter propagation delay times (maximum 65ns at 25C).
The maximum pulsewidth distortion of each type is less than 50ns; typical values are about 3ns for the PS9114 and 7ns for the PS9115.
These couplers require a typical supply voltage at the detector side of 5V (7V maximum).
The isolation voltage for both types is 2500V RMS.
Each of the new couplers is available in a 5-pin super small outline package (SSOP), with a minimum pin-to-pin distance of 1.27mm, allowing space saving designs.
These small packages offer a temperature resistance up to 260C.
Various international safety certificates are available.
The couplers are obtainable in two versions.
The PS9114 and PS9115 are suitable for soldering with lead, whereas the PS9114-A and PS9115-A are designed for lead-free soldering.
Test samples are available on request from Sunrise Electronics.
