SN74HC377N

Flip Flops Overview

The SN74HC377N is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features eight independent D-type flip-flops with positive-edge triggering and a clock enable input. The device utilizes CMOS technology for both input and output stages, providing non-inverting outputs. It operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting in a 20-pin PDIP package. Key electrical parameters include a maximum propagation delay of 160 ns at 2 V and output currents of ±5.2 mA. The component functions reliably across an operating temperature range of -40 °C to +85 °C.
