MM74HCT374N

Flip Flops Overview

The MM74HCT374N is an octal D-type flip-flop manufactured by onsemi, belonging to the 74HCT logic series. It features eight non-inverting D-type flip-flops with edge-triggered operation and three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 20-pin DIP package for through-hole mounting. Key electrical parameters include a maximum propagation delay of 32ns at 4.5V with a 50pF load, a clock frequency of 30MHz, and output drive capabilities suitable for interfacing with LS-TTL loads. It supports a wide operating temperature range from -40°C to +125°C.
