SD211

The Linear Systems SD210 and SD5000 series are discretes and quad monolithic arrays, respectively, of single-pole single-throw analog switches. These switches are n-channel enhancement-mode silicon field effect transistors built using double-diffusion MOS (DMOS) silicon gate technology. Surfacemount
versions (SST211, SD5400 Series) are also available.

This family of devices is designed to handle a wide variety of video, fast ATE, and telecom analog switching applications. They are capable of ultrafast switching speeds (t_r = 1 ns, t_OFF = 3 ns) and excellent transient response. Thanks to the reduced parasitic capacitances, DMOS can handle wideband signals with high off-isolation and minimum crosstalk.

The SD210 series of single-channel FETs is produced without Zener protection to reduce leakage and in Zener protected versions to reduce electrostatic discharge hazards. The SD5000 series is available in 16-lead dual inline surface mount or sidebraze ceramic packages. Analog signal voltage ranges up to
±10 V and frequencies up to 1 GHz can be controlled.

For surface-mount applications the SST211 series is offered in the TO-253 (SOT-143) package. The SD5400 series comes in the narrow body gull-wing SO-14 package.
