B3520/B3540
High Gain Level Shifter
Series
Description
Features
The B3520 series consists of enhancement-mode
MOSFETs designed for high speed low-glitch switching
in audio, video, and high-frequency wireless
applications. The CT3520 is optimized as a high speed
driver. With a source feedback resistor it can be uses as
a high speed LED Driver.

Low capacitance – 0.3pF typical
Low threshold – <1.5V max
Fast switching – ton<1ns
CMOS and TTL Compatible Input
The B3520 series uses Bay Linear ULTRA REL DMOS
Process for reliability and robust performance.
These MOSFETs utilize lateral construction to achieve
low capacitance and ultra-fast switching speeds. An
integrated Zener diode provides ESD protection.
