Flip Flops

SN74LS377DW Description

The SN74LS377DW from Texas Instruments is an 8-bit (octal) D-type flip-flop belonging to the 74LS series, designed for high-speed digital logic applications. It operates within a 4.75V to 5.25V supply range and features a positive-edge-triggered clock input, ensuring reliable data capture on rising clock transitions. With a 40 MHz clock frequency and a maximum propagation delay of 27ns at 5V (15pF load), this device delivers fast, stable performance in synchronous systems. The surface-mount (SOIC-20) package makes it suitable for compact PCB designs.
