The new logic parts are direct replacements for industry standard components and include AND, NAND, OR, NOR, XOR, inversion and buffering functions. In many applications, these low power logic devices draw less than 1µA of supply current, making them ideal for use in battery-powered products.
Providing a direct interface with TTL levels, the 74LVC1GXX family operates from 1.6V to 5.5V and the 74LVCE1GXX from 1.4.V to 5.5V. The wide input ranges allow both families of devices to be used for voltage level shifting. The output drive is ±24mA at 3.3V. When they are powered down, the logic devices' IOFF output circuitry ensures that outputs are disabled to prevent reverse current flow and to provide signal isolation.
Demand for single gate logic functions at the point of application is growing as the need for 4-gate logic solutions wanes. Such single gate solutions require minimal routing and provide for better board utilization with improved signal performance.
