SG1644
SG1644 is DUAL HIGH SPEED DRIVER manufactured by Microsemi.
DESCRIPTION
The SG1644/ SG3644 is a dual non-inverting monolithic high speed driver. This device utilizes high voltage Schottky logic to convert TTL signals to high speed outputs up to 18V. The totem pole outputs have 3A peak current capability, which enables them to drive 1000p F loads in typically less than 25ns. These speeds make it ideal for driving power MOSFETs and other large capacitive loads requiring high speed switching.
