Product details
Overview
HI3-0549-5 from Intersil is a 4-channel differential analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, and guaranteed rON matching. It operates in 0°C to 75°C industrial temperature range and is packaged in 16-lead PDIP for data acquisition systems interfacing externally powered sensors.
For engineers reviewing the HI3-0549-5 datasheet, HI3-0549-5 pinout, HI3-0549-5 application, or HI3-0549-5 equivalent, key selection criteria include differential channel count, break-before-make switching, ±15V rail-to-rail analog support, 12pF off-output capacitance, and 500ns typical access time under ±15V supplies.
Technical Context
The HI3-0549-5 implements a CMOS-DI (Dielectrically Isolated) process architecture with integrated overvoltage clamp circuitry that isolates faulted inputs without disturbing other channels. Its dual differential output structure (OUT A/OUT B) enables balanced signal routing while maintaining channel-to-channel isolation during ±33V overvoltage events.
Digital control uses TTL-compatible address inputs (A0, A1) and enable (EN), with level-shifting circuitry referenced to VREF to support logic drive up to 6V. The internal decoder drives P- and N-channel MOSFET pairs per switch path, ensuring matched on-resistance across all four differential pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 4 differential pairs (IN1A/IN1B through IN4A/IN4B) - supports true balanced signal selection |
| Analog Signal Range | ±15V - enables direct interface with industrial ±10V sensor outputs without level shifting |
| Overvoltage Protection | ±33V continuous, 70VP-P - protects against transients from external equipment without latch-up or damage |
| On Resistance (rON) | 1.5 kΩ typical at ±15V - ensures minimal gain error in precision measurement paths |
| Access Time | 500 ns typical - meets timing requirements for 1 MSPS data acquisition sampling |
| Off Output Capacitance | 12 pF - minimizes crosstalk and settling delay in high-impedance multiplexed front-ends |
| Power Dissipation | 7.5 mW typical - allows dense placement in thermally constrained industrial modules |
Pinout & Package
HI3-0549-5 is supplied in a 16-lead plastic dual-in-line package (PDIP) per JEDEC MS-001, with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 is identified by a notch or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+VSUPPLY) | Positive analog supply | Connects to +15V rail; powers internal switch array and protection circuitry |
| 2 (IN 1A) | Differential input A of channel 1 | Paired with pin 3 (IN 1B); forms first balanced input path |

Key Features
| Feature | Design Value |
|---|---|
| No channel interaction during overvoltage | Prevents fault propagation between differential pairs - critical for multi-sensor systems where one channel may experience transient faults while others remain operational |
| Break-before-make switching | Guarantees no momentary short between channels during address transitions - eliminates signal glitches in precision instrumentation |
| Guaranteed rON matching | ≤7% max ΔrON between any two channels - ensures consistent gain and offset across all 4 differential paths in calibrated measurement systems |
| 1kΩ fault protection resistance | Each input presents 1kΩ resistance during supply loss - limits current to safe levels if external sources remain active while HI3-0549-5 is unpowered |
| 44V maximum supply rating | Supports extended voltage margins beyond ±15V rails - accommodates design tolerances and transient overshoot without device stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI9P0549-9Z | Same HI-549 function but in 16-lead SOIC package with −40°C to +85°C temperature range and Pb-free finish | Preferred for surface-mount production and extended temperature environments; not drop-in compatible due to different footprint and thermal profile | Select HI9P0549-9Z for new designs requiring RoHS-compliant SMT assembly and wider operating range |
| ADG509A | 4-channel differential CMOS MUX with ±15V analog range but no active overvoltage protection; 45Ω rON, 100ns access time | Suitable for benign lab environments where external protection is implemented; lacks built-in ±33V fault tolerance | Choose ADG509A only when overvoltage risk is mitigated externally and lower on-resistance is prioritized over fault resilience |
Compared with HI3-0549-5, HI9P0549-9Z offers modern packaging and extended temperature operation but requires PCB redesign, while ADG509A delivers faster switching and lower rON at the cost of requiring external overvoltage protection circuitry.

FAQ
What is the maximum analog overvoltage the HI3-0549-5 can withstand without damage?
The HI3-0549-5 sustains continuous ±33V analog overvoltage relative to its supplies and up to 70VP-P fault conditions without damage or signal path disturbance. This protection remains active even if the device loses power, with each input presenting 1kΩ resistance to limit current. These ratings are specified in the Absolute Maximum Ratings table of the FN3150 datasheet and validated across the full 0°C to 75°C operating range for HI3-0549-5.
Does the HI3-0549-5 support TTL-level digital control inputs?
Yes, the HI3-0549-5 accepts TTL-compatible digital inputs: logic low ≤0.8V and logic high ≥4.0V on ENABLE, A0, and A1 pins. Its internal level-shifter circuitry allows reliable operation with standard 5V TTL drivers without external pull-ups. The HI3-0549-5 datasheet specifies VAH = 4.0V and VAL = 0.8V under full temperature range, confirming native TTL compatibility without additional interface circuitry.
What is the on-resistance matching specification for the HI3-0549-5?
The HI3-0549-5 guarantees ΔrON ≤7.0% between any two channels at 25°C, as stated in the Electrical Specifications table. This matching holds across the full ±15V analog signal range and supports precision applications like calibrated sensor multiplexing where gain consistency is critical. Measured rON is 1.5 kΩ typical and 1.8 kΩ maximum at 25°C, with worst-case 2.0 kΩ over temperature.
Can the HI3-0549-5 operate with supply voltages other than ±15V?
Yes, the HI3-0549-5 supports supply voltages from ±5V up to ±22V on V+ and −25V on V−, with absolute maximum V+ to V− rating of +44V. Performance parameters such as access time and rON vary with supply voltage - for example, access time degrades from 500ns at ±15V to 1.0μs at ±5V. The HI3-0549-5 datasheet provides normalized rON vs. supply voltage curves confirming stable operation across this range.
Is there a pin-compatible replacement for the HI3-0549-5 in surface-mount packaging?
The HI9P0549-9Z is the direct functional replacement for HI3-0549-5 in 16-lead SOIC packaging, sharing identical pinout, electrical specifications, and differential 4-channel architecture. However, it is not pin-compatible due to differing package dimensions, land patterns, and thermal characteristics. HI9P0549-9Z operates from −40°C to +85°C and features Pb-free finish, making it suitable for new SMT designs but requiring PCB layout revision.
