 74LVC1Gxx series

Diodes Inc. announces the 74LVC1Gxx series of single-gate logic products. Built on a 5V CMOS process, the initial products covers AND, NAND, OR, NOR, XOR, inversion and buffering functions. Offered as cost effective replacements for industry standard parts in point-of-application general purpose logic, level shifting and signal isolation applications, the products come in SOT25 and SOT353 package options.

The operating voltage range of the 74LVC1Gxx series is 1.65V to 5.5V, enabling it to support portable battery operated and traditional 5V applications. To address higher performance application requirements, the 74LVCE1Gxx extended specification products operate down to 1.4V, and provide a 30 percent enhancement in switching speeds at 1.8V as compared to the standard LVC family. Both families have 5.5V tolerant inputs, enabling the creation of voltage translation solutions.

Suited for communication, computing, consumer and networking equipment, the logic products will, in many applications, draw less than 1?A of supply current, ensuring low power consumption. Their IOFF output circuitry means that the output is disabled when the device is powered down, preventing damaging backflow current from entering the device or unnecessarily loading shared signal lines.

Keh-Shew Lu, president and CEO, Diodes Inc. noted that "Demand for single gate logic is growing very rapidly as the need for traditional 4 gate logic wanes. Many suppliers though don't have ownership of low pin-count assembly lines and are finding themselves on increasingly long allocation. Diodes has a world-class assembly facility that's well suited to the manufacture of low pin-count SOT25 and SOT353 packages. We're pleased to be able to leverage this capability to provide users with an alternative source of quality, high-performance logic products."
