Product details
Overview
HI9P0303-9 from Intersil is a dual SPDT CMOS analog switch fabricated using dielectric isolation technology, designed for precision signal routing in ±15V dual-supply systems. It delivers 35Ω typical on-resistance at 25°C, 40pA leakage at 25°C, and 60ns break-before-make delay - enabling low-error sample-and-hold and op amp gain switching in industrial instrumentation.
For engineers reviewing the HI9P0303-9 datasheet, HI9P0303-9 pinout, HI9P0303-9 application, or HI9P0303-9 equivalent, key selection criteria include its symmetrical switch architecture, TTL/CMOS logic compatibility (0.8V/4V thresholds), ±15V analog signal range, and SOIC-14 RoHS-compliant packaging for space-constrained PCBs.
Technical Context
The HI9P0303-9 integrates two independent SPDT analog switches with break-before-make timing to prevent signal shorting during state transitions. Each switch features matched N- and P-channel MOSFETs in a symmetrical topology, supporting bidirectional analog signal flow across the full ±15V range with minimal charge injection (30pC) and low capacitance (14–16pF off-state).
Its digital interface accepts TTL/CMOS logic levels (VINL ≤ 0.8V, VINH ≥ 4V) and drives internal level shifters to control high-voltage analog paths. Power consumption remains low (1.0mW typical) due to CMOS gate drive and dielectric isolation, enabling use in portable and battery-operated systems without thermal derating concerns.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1434BRUZ | Higher on-resistance (1.3Ω typical), wider supply range (±15V to ±22V), but no break-before-make guarantee | Better suited for high-voltage fault-tolerant systems; less optimal for precision sample-and-hold due to higher RON and leakage | Select ADG1434BRUZ only when absolute maximum supply voltage >44V is required and break-before-make is not critical |
| MAX4634EUB+ | Lower leakage (0.5pA typ), smaller 10-pin µMAX package, but limited to ±5.5V supplies | Ideal for low-voltage portable designs; incompatible with ±15V industrial signal chains | Choose MAX4634EUB+ for battery-powered devices with <±6V rails and ultra-low leakage requirements |
Compared with HI9P0303-9, ADG1434BRUZ offers extended voltage tolerance but sacrifices guaranteed break-before-make timing and adds 37× higher on-resistance, while MAX4634EUB+ achieves sub-picoamp leakage at the cost of halving the usable analog signal range - making HI9P0303-9 the balanced choice for ±15V precision switching with deterministic timing.

FAQ
What is the operating temperature range for HI9P0303-9?
The HI9P0303-9 is rated for operation from −40°C to +85°C, matching the "-9" suffix designation in the ordering code. This range is validated per the Absolute Maximum Ratings table and Electrical Specifications section of the FN3125 datasheet, and applies specifically to the SOIC-packaged HI9P0303-9Z variant.
Does HI9P0303-9 support single-supply operation?
Yes, HI9P0303-9 can operate from a single +30V supply with V− tied to ground, or asymmetric supplies such as +15V/0V, provided the total voltage difference between V+ and V− does not exceed 44V. The analog signal range remains centered around the V− rail, so proper biasing is required for AC-coupled signals.
Is HI9P0303-9 pin-compatible with other HI-303 variants like HI1-0303-2?
No - while all HI-303 variants share identical pin functions and electrical behavior, HI9P0303-9 uses a 14-lead SOIC package (M14.15), whereas HI1-0303-2 uses a 14-lead CERDIP (F14.3) and HI3-0303-5Z uses a 14-lead PDIP (E14.3). Footprints and thermal profiles differ significantly; PCB layout changes are required for substitution.
What is the maximum analog input voltage allowed on HI9P0303-9?
The absolute maximum analog input voltage on any S or D pin is (V+) +1.5V to (V−) −1.5V, per the Absolute Maximum Ratings table. For ±15V supplies, this defines a safe analog range of −16.5V to +16.5V - though the specified functional range remains ±15V to ensure linearity and low on-resistance performance.
How does the break-before-make timing work in HI9P0303-9?
HI9P0303-9 guarantees a minimum 60ns interval between turn-off of one switch path and turn-on of the alternate path within each SPDT pair. This is implemented via internal delay circuitry in the switch driver stage and is verified under all temperature and supply conditions - preventing transient short-circuits in multiplexed signal paths.
