DG540AP/883

Analog Switches - Special Purpose Overview

The DG540AP/883 is a high-performance monolithic wideband video switch manufactured by Vishay Siliconix. It features four independent SPST channels utilizing a proprietary 'T' switch configuration to achieve low crosstalk and high off-isolation. The device operates within an extended temperature range of -55 °C to +125 °C and is housed in a 20-pin sidebraze dual-in-line package. Key electrical specifications include a maximum on-resistance of 60 Ω, a bandwidth of 500 MHz, and a turn-on time of 70 ns at full temperature. It supports supply voltages from V+ = 15 V and V- = -3 V, with a maximum power dissipation of 900 mW.

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number suffix matches the specific military-grade qualification requirements. Ensure proper handling procedures are followed due to the sensitive nature of the semiconductor materials and packaging.

Analog Switches - Special Purpose Selection Notes

Select this component when high-frequency analog signal switching is required alongside strict isolation needs. The wide operating temperature range makes it suitable for harsh environments. Verify that the 20-pin sidebraze package fits the available PCB footprint and that the 60 Ω on-resistance meets the system's insertion loss constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the DG540 family of wideband video switches, which also includes the DG541 and DG542 variants. These devices share similar architectural features but differ in pin configurations and specific performance metrics like bandwidth and isolation levels. The DG540 specifically offers the highest isolation among the three.
