Single-gate logic devices

21 July 2010 Analogue, Mixed Signal, LSI

Diodes Incorporated has released its very first family of single-gate logic products. Built on an advanced 5 V CMOS process, the 74LVC1Gxx series provides users with the eight most popular standard logic functions in SOT25 and SOT353 package options, and the 74LVCE1Gxx series offers enhanced performance versions of these same functions.

Suitable for use in a variety of communication, computing, consumer and networking equipment, the initial offering covers AND, NAND, OR, NOR, XOR, inversion and buffering functions. The single-gate products are cost effective replacements for industry standard parts in point-of-application general-purpose logic, level shifting and signal isolation applications.

At 1,65 V to 5,5 V, the operating voltage range of the 74LVC1Gxx series is wide, enabling it to support both portable battery operated and traditional 5 V applications. To address higher performance application requirements, the 74LVCE1Gxx extends operation down to 1,4 V, and provide a 30% enhancement in switching speeds at 1,8 V as compared to the standard LVC family. Both families have 5,5 V tolerant inputs, enabling the creation of voltage translation solutions.

In many applications, the logic products will draw less than 1 μA 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.
