Product Overview
The SN74LS378N is a high-performance D-type flip-flop from Texas Instruments, designed for general-purpose storage applications in digital systems. It features six D-type flip-flops with a common clock (CLK) and enable (G) input, providing non-inverting outputs (Q). The device is fabricated using advanced low-power Schottky technology, offering a balance of speed and power consumption. Housed in a 16-pin PDIP package, it is suitable for through-hole mounting in industrial and consumer electronics.
