HI1-5046A-7

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-5046A-7 is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Harris Corporation. It operates within a supply voltage range of ±3V to ±18V and supports signal voltages from -18V to +18V. The device features an on-resistance (Ron) of typically 25Ω, with a maximum value of 45Ω at room temperature. It offers high off-isolation of 80dB and low charge injection of 50pC. The component is housed in a 16-pin ceramic dual in-line package (CDIP) and is rated for an operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'A-7' against manufacturer documentation to confirm pinout and material specifications. Confirm RoHS compliance status as older Harris components may not meet current environmental standards. Validate that the ceramic package variant meets thermal requirements for the intended harsh environment application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dielectric isolation is required to prevent latch-up in high-voltage environments. Compare the 25Ω typical on-resistance against system loss budgets. Ensure the 16-pin CDIP package fits the available PCB footprint or socket constraints. Verify that the ±18V signal handling capability exceeds the maximum expected input amplitude.
