The Calogic SD310 is a 30V analog switch driver without a
built-in protection diode from gate to substrate for use with
SD312 and SD314 DMOS analog switches.
The SD312 is a high performance, high-speed, high-voltage,
and low resistance analog switch capable of switching
±5V
signals. The maximum threshold of 2V permits simple direct
TTL an CMOS driving for small applications.
The SD314 is DMOS analog switch capable of switching
±10V
analog signals with all other parameters identical to
those of SD312.
All three devices are manufactured with an implanted
high-speed, high-voltage, and low resistance double-diffused
MOS (DMOS) process. SD310, SD312 and SD314 devices
also have no built-in protection diode to enhance performance
in high impedance circuits. The devices are available in
4-lead hermetic TO-72 package and in die form for hybrid
applications. Custom devices based on SD310, SD312 and
SD314 can also be ordered.
