Linear Systems Announces the Immediate Availability of SD5400 / SD5000 Family of Quad N-Channel Enhancement Mode Lateral DMOS Analog Switches

FREMONT, CA – Linear Systems is announcing the immediate availability of the SD5400 / SD5000 Family of Quad N-Channel Enhancement Mode Lateral DMOS Analog Switches, specifically designed for high-speed switching applications. These ultra-fast switches offer improved accuracy, speed, and throughput, with less glitching or distortion than JFETs or multiplexers. Designed for high-frequency RF operation, they provide switching speeds of 1ns with a unique combination of 70 ohms "ON" resistance and a reverse transfer capacitance of 0.5 pF. A maximum threshold of 1.5 volts permits simple TTL and CMOS driving for small signal applications.

The SD5400 / SD5000 can switch analog signals up to +/- 10 volts, while the SD5401 / SD5001 can switch signals up to +/- 5 volts. All versions include gate ESD protection with zener diodes.

The surface mount versions, SD5400 / SD5401, are available in 14 and 16 pin narrow body SOIC packages. The thru-hole versions, SD5000N / SD5001N, are available in 16 pin DIP packages. All package types are available with special electrical selection, including bare die form.

Summary of Features:

- High Speed Switching (td (ON) / (OFF) = 1ns max)

- Ultra Low Reverse Capacitance (Crss = 0.5 pF max)

- Low Turn-On Threshold Voltage (Vgs(th) = 1.5V max)

- Switches Analog Signals up to +/- 10 volts

- CMOS and TTL Compatible

- Second Source Replacement for Calogic and Siliconix SD5400 / SD5000 Families

- Available in Surface Mount SOIC-14, 16 pin, PDIP-16 Packages, and Bare Die

Applications:

- ATE (Automatic Test Equipment) Analog Switch

- Analog to Digital and Digital to Analog Converters

- Laser Drivers

- Medical Imaging

- Multiplexer

- Sample and Hold

- Switch Driver

- Vision Systems

Delivery: Factory Stock
