DM74ALS09N

Inverter Gates Overview

The DM74ALS09N is a quad 2-input AND gate with open-collector outputs manufactured by onsemi. It operates within a supply voltage range of 4.5V to 5.5V and supports a free air operating temperature from 0°C to +70°C. The device utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process. Key electrical characteristics include a maximum propagation delay of 54ns for LOW-to-HIGH transitions and 5ns for HIGH-to-LOW transitions at 50pF load. It features a low level output current capability of 8mA and requires external pull-up resistors for logical operation.
