Power down protection is provided on FLIP-FLOP fabricated with sub-micron silicon inputs and 0 to 7V can be accepted on inputs with 2 gate and double-layer metal wiring C MOS no regard to the supply voltage. This device can be used to interface 5V to 3V systems. technology. it is designed to operate from 2V to 5.5V, making this device ideal for portable Its available in the commercial and extended applications. temperature range. All inputs and output are equipped with protection circuits against static This D-Type flip-flop is controlled by a clock input (CK). On the positive transition of the clock, the Q discharge, giving them ESD immunity and output will be set to the logic state that was setup transient excess voltage. at the D input.
