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.
Key advantages of the new logic family include: a 1.65V to 5.5V range, allowing use in both battery-operated and traditional 5V applications; voltage tolerant inputs, to 5.5V, for use in a mixed-voltage environment; supply current of less than 1µA in many applications; and 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 3.3V or 5.5V for voltage translation applications.
New ICs in the expanded family, which are direct drop-in replacements for industry-standard parts and are available at highly competitive prices, include:
• 74LVC00AT14-13 – Quadruple 2-Input NAND Gates
• 74LVC04AT14-13 – Hex Inverters
