HI3-0539-5

Overview

The Intersil HI3-0539-5 is a precision, 4-channel, low-level differential multiplexer. It features two digital inputs for channel selection and an Enable input to disconnect all channels. Performance is guaranteed over a voltage range of ±10V, optimized for low-level differential signals. Key electrical parameters include a typical on-resistance variation (∆rON) of 5.5Ω at 125°C, an on-current variation (∆ID(ON)) of 0.6nA at 125°C, charge injection of 0.1pC, and crosstalk of -124dB. The device exhibits a settling time of 900ns at ±0.01% accuracy. It operates with a wide supply range from ±5V to ±18V and incorporates break-before-make switching with no latch-up susceptibility.

Feature Summary

• Monolithic 4-channel differential architecture designed for precision signal routing
• Break-before-make switching mechanism ensures signal integrity during channel transitions
• Immunity to latch-up conditions enhances operational reliability in varying environments

Applications
