HI1-5048-7

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-5048-7 is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Harris Corporation. It features two independent channels within a 16-pin ceramic DIP package. The device operates with supply voltages ranging from -15 V to +15 V, providing a total supply range of 30 V. The typical on-resistance (Ron) is nominally 25 Ω, with a maximum specified at 45 Ω. Break-before-make switching action prevents signal overlap during channel transitions. The component supports TTL and CMOS logic compatibility for control inputs.

• Multiplexing applications requiring low distortion
• Programmable gain amplifier input selection
• Test and measurement equipment signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix '7' against official Harris datasheets to confirm pinout and electrical tolerances, as suffixes often denote military or extended temperature grades. Confirm RoHS compliance status, as older Harris CMOS parts may not meet current environmental standards. Validate package dimensions and lead finish specifications against the target PCB footprint requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog switching is required with high voltage tolerance. Ensure the application signal levels remain within the ±15 V supply limits to prevent damage. Consider the 45 Ω maximum on-resistance impact on signal attenuation if driving low impedance loads. Verify that the break-before-make timing meets the system's glitch immunity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HI1-5048-7 belongs to the HI-504x series of CMOS analog switches produced by Harris Semiconductor. This family is characterized by low power consumption and high speed performance relative to earlier bipolar technologies. The part is designed for harsh environment applications, often featuring ceramic packaging for reliability in aerospace or industrial settings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

HI1-5048-5: Plastic DIP variant with similar electrical characteristics but different thermal and mechanical properties. HI1-5048-2: Ceramic DIP version; verify pinout compatibility. HI1-5048-1: Alternative package option. Cross-reference Ron and leakage specs with newer equivalents from Renesas or Intersil if sourcing obsolete Harris inventory.
