These devices are positive-edge-triggered D-type flip-flops with a direct clear ( CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output. These devices are positive-edge-triggered D-type flip-flops with a direct clear ( CLR) input.

This quadruple silicon-gate CMOS analog switch is designed for 1V to 5.5V VCC operation. The switch is designed to handle both analog and digital signals. Each switch permits signals with amplitudes of up to 5.5V (peak) to be transmitted in either direction. Each switch section has its own enable input control (C). A high-level voltage applied to C turns on the associated switch section. Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.
