DESCRIPTION
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 capaci-
tive 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 applica-
tions, and the Hermetic TO-66 (R-package) for military use.
These packages offer improved thermal performance for applica-
tions requiring high frequencies and/or high peak currents.

... SG1644 is one solution to this problem. This combination is especially suited for full bridge applications where high input capacitance MOSFETs are being used. Diodes D1 and D2 are necessary if the leakage inductance of the drive transformer will drive the output pins negative. 9/91 Rev 1.2 6/97 Copyright 1997 SG1644/SG2644/SG3644 11861 Western Avenue 6 L INFINITY Microelectronics Inc.
