The document describes a high-speed CMOS single positive edge triggered D-type flip-flop. The flip-flop is fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology and is designed to operate from 4.5V to 5.5V. It features high speed, low power dissipation, compatibility with TTL outputs, and can be used to interface 5V to 3V systems.
The 74V1T79 is an advanced high-speed CMOS single positive edge triggered D-type flip-flop fabricated with sub-micron silicon gate and double-layer metal wiring CMOS technology. It is designed to operate from 4.5V to 5.5V, making this device ideal for portable applications. The flip-flop is controlled by a clock input (CK), and on the positive transition of the clock, the Q output will be set to the logic state that was setup at the D input.
The device features power down protection on inputs, allowing 0 to 7V to be accepted on inputs with no regard to the supply voltage. It is available in the commercial and extended temperature range. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage. It is available in SOT23-5L and SOT323-5L packages.
