SG1644/SG2644/SG3644
DUAL HIGH SPEED DRIVER
DESCRIPTION |
FEATURES |
The SG1644, 2644, 3644 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 1000pF loads in typically less than 25ns. These speeds make it ideal for driving power MOSFETs and other large capacitive loads requiring high speed switching.
In addition to the standard packages, Silicon General offers the 16 pin S.O.I.C. (DW-package) for commercial and industrial applications, and the Hermetic TO-66 (R-package) for military use. These packages offer improved thermal performance for applications requiring high frequencies and/or high peak currents.
∙Totem pole outputs with 3.0A peak current capability.
∙Supply voltage to 22V.
∙Rise and fall times less than 25ns.
∙Propagation delays less than 20ns.
∙Non-inverting high-speed high-voltage Schottky logic.
∙Efficient operation at high frequency.
∙Available in:
8 Pin Plastic and Ceramic DIP
14 Pin Ceramic DIP
16 Pin Plastic S.O.I.C.
20 Pin LCC
TO-99
TO-66
