SN74LVC1G79/SN74LVC1G79-Q1 D-Type Flip-Flop Texas Instruments SN74LVC1G79/SN74LVC1G79-Q1 Single D-Type Flip-Flop is designed for 1.65V to 5.5V VCC operation. When data at the data (D) input meets the setup time requirement, the data is transferred to the Q output on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the level at the output. The SN74LVC1G79 is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs when the device is powered down. This feature inhibits current backflow into the device which prevents damage to the device. The SN74LVC1G79-Q1 devices are AEC-Q100 qualified for automotive applications.
