General-purpose CMOS logic ICs

18 April 2012 Analogue, Mixed Signal, LSI

Diodes Incorporated has expanded its low-voltage CMOS (LVC) general–purpose logic family beyond single- and dual-gate products, with the addition of 10 popular functions in

14-pin TSSOP packages.

The new 74LVCxx logic ICs are designed for a broad range of computing applications including desktop and notebook PCs, computer peripherals like hard-disk and optical drives, networking equipment such as routers and hubs, as well as an array of consumer equipment including TVs, set-top boxes, DVRs and gaming consoles.

Currently available devices in the family include hex inverters, hex inverters and buffers with open drains, and hex inverters with Schmitt trigger inputs. Variations of quadruple NAND, AND, OR, XOR and two types of tri-state buffer gates will soon be available.

The new logic family offers a 1,65 V to 5,5 V range, allowing use in both battery-operated and traditional 5 V applications. The devices have voltage tolerant inputs, to 5,5 V, for use in a mixed-voltage environment, and draw supply current of less than 1 &#mu;A in many applications. They incorporate I(OFF) output circuitry which disables the outputs, preventing backflow current when the device is powered down. Additionally, the device inputs can be driven at 3,3 V or 5,5 V for voltage translation applications.
