SN74LV74APW

SN74LV74APW Description

The SN74LV74APW from Texas Instruments is a dual D-type flip-flop with set (preset) and reset functionality, designed for high-speed digital applications. Packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package), this device operates within a 2V to 5.5V supply range, making it suitable for both 3.3V and 5V systems. With a 140 MHz clock frequency and a max propagation delay of 9.3ns at 5V, it ensures reliable performance in timing-critical circuits. The complementary outputs provide flexibility in interfacing with other logic devices, while its low quiescent current (20 µA) enhances power efficiency.
