Little logic for reducing supply voltages

Fairchild has expanded its portfolio of ultra-low-power TinyLogic single- and dual-gate logic devices.

Fairchild has expanded its portfolio of ultra-low-power TinyLogic single- and dual-gate logic devices.

The TinyLogic ULP Series' dramatic improvement in reducing power consumption - up to 50% less than standard logic - significantly increases battery run time for portable equipment.

These devices address the demands of newer ASICs, microprocessors and DSPs operating at lower voltages.

Operating over a supply range of 0.9-3.3V, this family is ideal for low-voltage battery-powered portable applications.

Propagation delays for the 18 new NC7SPxx devices are 6ns at 1.8V and 3ns at 3.3V.

Another 18 new NC7SVxx models offer 1.9ns propagation delays at 1.8V, and 1ns at 3.3V.

The TinyLogic ULP family also provides overvoltage tolerant (OVT) inputs and outputs that interface easily with any device operating up to 3.6V.

Combining Fairchild's low-noise design expertise (eg Quiet Series logic, graduated turn-on methodology) with fast switching assures noise-free logic at lower voltage levels - important as logic levels trend below 1.8V.

The absence of noise "ringing", coupled with short propagation delays, and rise and fall times, is key to TinyLogic ULP's highly desirable performance characteristics for today's decreasing-voltage environment.

TinyLogic ultra-low-power logic devices are available in five- and six-lead SC70 packaging.

Availability in leadless chip scale MicroPak (1.45mm2) packaging is scheduled for Q4 2002.

Eight-lead US8 (6.2mm2) is planned for early next year.
