SG1644/SG2644/SG3644
DUAL HIGH SPEED DRIVER
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 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.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specfiications apply over the operating ambient temperatures for SG1644 with -55°C ≤ TA ≤ 125°C, SG2644 with -25°C
≤ TA ≤ 85°C, SG3644 with 0°C ≤ TA ≤ 70°C, and VCC = 20V. Low duty cycle pulse testing techniques are used which maintains junction and case
temperatures equal to the ambient temperature.)
