DESCRIPTION

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.
