DM74ALS374SJX

Overview

The DM74ALS374SJX is an octal D-type flip-flop with 3-state outputs manufactured by onsemi. It belongs to the 74ALS logic series and utilizes bipolar technology. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 35 MHz. It features a propagation delay of 16 ns at 5 V with 50 pF load, delivering output currents of -2.6 mA (high) and 24 mA (low). Packaged in a 20-SOP surface-mount format, it functions as a single circuit with eight bits per element.
