MOTOROLA SEMICONDUCTOR TECHNICAL DATA UB-Suffix Series CMOS Gates The UB Series logic gates are constructed with P and N channel enhancement mode devices in a single monolithic structure (Complementary MOS). Their primary use is where low power dissipation and/or high noise immunity is desired. The UB set of CMOS gates are inverting non–buffered functions. • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Linear and Oscillator Applications • Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range • Double Diode Protection on All Inputs • Pin–for–Pin Replacements for Corresponding CD4000 Series UB Suffix Devices Quad 2-Input NOR Gate Dual 4-Input NOR Gate Quad 2-Input NAND Gate Dual 4-Input NAND Gate Triple 3-Input NAN [ ... ]
