SD5400CY SOIC 14L ROHS

Overview

The SD5400CY is a quad N-channel lateral DMOS switch in a SOIC-14 package. It features four enhancement-mode MOSFETs on a common substrate with Zener input protection. Key parameters include a drain-source breakdown voltage of 20 V, a maximum gate threshold voltage of 1.5 V, and an on-resistance of 75 Ω at VGS = 5 V. The reverse transfer capacitance is 0.5 pF, and the turn-on time is 2 ns. It handles ±10-V analog signals.

Feature Summary

• Quad SPST switch configuration with integrated zener diode input protection
• Ultra-high speed switching utilizing lateral DMOS construction
• Low interelectrode capacitance to minimize insertion loss and crosstalk

Applications

• Fast sample-and-hold circuits
• Video signal switching
• Multiplexer systems
• DAC deglitchers

Procurement Notes

Verify the specific ordering suffix 'CY' corresponds to the SOIC 14L RoHS package as documented in the manufacturer's standard part call-out list. Confirm that the device meets the required operating temperature range and power dissipation limits for your application environment before finalizing procurement.

Selection Notes

Select this component when high-speed switching and low distortion are critical requirements. The SD5400 series offers superior performance compared to JFETs or multiplexers regarding glitching and distortion. Ensure the driving circuitry can provide the necessary gate voltage levels to achieve the specified low on-resistance characteristics.

Part Context

This device belongs to the SD5000/SD5400 series of monolithic switches designed by Linear Integrated Systems. These devices replace discontinued Siliconix products and utilize a proprietary DMOS process. The series includes variants rated for different voltage levels, such as the SD5001/SD5401 which handle ±5-V signals.

Replacement Considerations

For similar products packaged in TO-206AF (TO-72) and TO-253 (SOT-143), refer to the SD211DE/SST211 series.
