High Speed DMOS
N-Channel Switch
CORPORATION
SD403
FEATURES
DESCRIPTION
The Calogic SD403 is an N-Channel Enhancement-Mode
Lateral DMOS FET. This product has very low capacitance,
(c
rss
< 0.4pf typical) allowing for high speed switching (t
r
1ns).
The SD403 is a high gain device (19mmhos) and has good
performance values for sample and hold circuits, video
switches and switch drivers where lower capacitance and high
speed switching are critical.
