Diodes Inc. has added 10 functions in its 14-pin TSSOP logic IC family to expand its low-voltage CMOS (LVC) generalCpurpose logic family. According to the company, the 74LVCxx logic ICs are engineered for computing applications such as desktops and notebooks, computer peripherals such as hard disks and optical drives, networking equipment such as routers and hubs, and consumer devices such as TVs, STBs, DVRs and gaming consoles.

The devices operate in a 1.65-5.5V range, allowing use in both battery-operated and traditional 5V applications. The ICs feature voltage tolerant inputs up to 5.5V that is geared for mixed-voltage environments. Likewise, the 74LVCxx has a supply current of less than 1?A in many applications and I(OFF) output circuitry that disables the outputs preventing backflow current when the device is powered down. Additionally, the device inputs can be driven at 3.3V or 5.5V for voltage translation applications, explained Diodes.

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.
