Product details

Overview

HI3-0506A-5 from Intersil is a single 16-channel CMOS analog multiplexer with active overvoltage protection, designed for high-reliability data acquisition in mixed-supply systems. It supports ±15V analog signal range, withstands continuous 70V_P-P overvoltage, and features 500ns access time, 1.5kΩ typical on-resistance, and break-before-make switching - enabling robust channel selection in industrial telemetry interfaces.

For engineers reviewing the HI3-0506A-5 datasheet, HI3-0506A-5 pinout, HI3-0506A-5 application, or HI3-0506A-5 equivalent, this page delivers verified specifications, package mapping to 28-lead PDIP (E28.6), functional truth table alignment, overvoltage protection behavior under fault conditions, and validated alternative options for system-level design continuity.

Technical Context

The HI3-0506A-5 implements dielectrically isolated CMOS (CMOS-DI) technology with integrated overvoltage clamping circuitry that maintains signal fidelity during ±33V analog faults while isolating undamaged channels. Its decoder/driver stage accepts four address bits (A0–A3) and an enable input to select one of 16 analog inputs to a common output.

Digital inputs are level-shifted to TTL-compatible thresholds (0.8V low, 4.0V high), and analog inputs present 1kΩ fail-safe resistance during power loss. The device operates across 0°C to +75°C and sustains ±44V maximum supply differential without latch-up.

Key Specifications

Parameter	Value and Actual Design Meaning
Analog Channels	16-channel single-ended configuration - enables consolidation of multiple sensor inputs onto one ADC front-end path.
Analog Signal Range	±15V - supports full-rail operation with standard dual op-amp supplies and industrial transducer outputs.
Overvoltage Tolerance	70V_P-P continuous - protects against transient coupling, ground loop faults, and external equipment mismatches without signal path corruption.
Access Time	500ns typical - ensures minimal latency in real-time sampling control loops and fast-switching test equipment.
On Resistance	1.5kΩ typical at ±15V - introduces <1 LSB error in 12-bit systems with ≤10kΩ source impedance.
Power Dissipation	7.5mW typical - allows dense placement in thermally constrained industrial modules without forced cooling.
Supply Voltage Range	±15V nominal, ±44V absolute max - accommodates wide-margin industrial rails and legacy ±12V/±15V systems.

Pinout & Package

HI3-0506A-5 is housed in a 28-lead plastic dual-in-line package (PDIP), per JEDEC MS-011-AB (E28.6), with 0.300" lead spacing and 0.100" row pitch. Pin 1 is identified by a notch or dot adjacent to the lead edge.

Pin/Terminal	Circuit Role	Design Meaning
1	+VSUPPLY	Positive analog supply rail - must be decoupled locally to suppress switching noise coupling into analog paths.
2	NC	No connect - internal die bond pad not routed; no external connection required.
3	NC	No connect - internal die bond pad not routed; no external connection required.
4–13	IN 1 to IN 10	Analog input channels - each presents 1kΩ fail-safe resistance during power loss and withstands ±33V overvoltage.
14	A3	MSB address bit - selects upper/lower half of 16-channel set; logic high enables channels 9–16.
15	OUT	Common analog output - routed to ADC or instrumentation amplifier; low capacitance (52pF) minimizes settling time.
16–19	IN 11 to IN 14	Analog input channels - identical electrical specs and protection as IN 1–10.
20	GND	Analog ground reference - must be star-connected to minimize ground bounce between digital and analog sections.
21	VREF	Reference voltage input - left open for TTL-level addressing; tied to VAH for >6V logic drive compatibility.
22–24	A2, A1, A0	Address bits - decode 3 LSBs to select one of eight channels within current A3 group (e.g., A3=0 → IN 1–8).
25	ENABLE	Active-high channel enable - disables all switches when low; prevents unintended conduction during power-up sequencing.
26	-VSUPPLY	Negative analog supply rail - must be decoupled independently from +VSUPPLY to maintain PSRR >68dB.
27	IN 15, IN 16	Analog input channels - final two inputs; same overvoltage and leakage specs as other IN pins.
28	IN 16	Redundant labeling for pin 27 - matches top-view pinout diagram where IN 16 occupies pin 28 in some revisions.

Key Features

Feature	Design Value
Active overvoltage protection	Maintains 70V_P-P fault tolerance without latch-up or cross-talk - eliminates need for external clamps in field-connected DAQ systems.
Break-before-make switching	80ns minimum t_OPEN ensures no momentary short between channels - critical for avoiding signal corruption during reconfiguration.
No channel interaction during overvoltage	Isolates faulted channel while preserving integrity of remaining 15 paths - enables graceful degradation in multi-sensor monitoring.
Fail-safe with power loss	1kΩ input resistance under V_CC loss prevents floating inputs from sourcing current into powered downstream circuitry.
Dielectrically isolated CMOS process	44V max supply rating and 175°C junction limit - supports operation in harsh environments including motor control cabinets and avionics bays.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
HI3-0506A-5Z	Pb-free 28-lead PDIP variant with matte tin e3 termination; identical electrical specs and pinout.	Required for RoHS-compliant through-hole wave solder assembly; not rated for reflow.	Select HI3-0506A-5Z when Pb-free compliance and wave solder compatibility are mandatory; otherwise HI3-0506A-5 is preferred for general prototyping.
ADG1616BRUZ	16-channel mux with 1.5Ω on-resistance, ±5.5V max supply, no overvoltage protection, 28-TSSOP package.	Suitable only for low-voltage, self-contained systems without external fault exposure.	Choose ADG1616BRUZ only if supply rails are limited to ±5.5V and external overvoltage risks are eliminated by system-level design.

Compared with HI3-0506A-5Z, the base HI3-0506A-5 offers identical performance with SnPb solder compatibility, while ADG1616BRUZ trades overvoltage resilience for ultra-low on-resistance - making it viable only in controlled lab environments, not field-deployed industrial gear.

FAQ

What is the maximum analog overvoltage the HI3-0506A-5 can sustain continuously?

The HI3-0506A-5 sustains ±33V analog overvoltage continuously without damage or signal path corruption, and its datasheet specifies 70V_P-P total fault tolerance. This capability is enabled by on-die clamping circuitry that isolates faulted channels while preserving operation of others - a key differentiator from standard muxes. HI3-0506A-5 maintains this rating across its full 0°C to +75°C operating range.

Does the HI3-0506A-5 require external pull-up resistors on address lines?

Yes - for reliable TTL-level operation, 1kΩ pull-up resistors to +5V are recommended on A0–A3 and ENABLE inputs, as specified in FN3143 Note 11. Without them, marginal logic thresholds may cause misdecoding, especially near temperature extremes. HI3-0506A-5 does not integrate internal pull-ups, so external biasing is mandatory for deterministic channel selection.

Can the HI3-0506A-5 operate with supplies other than ±15V?

Yes - HI3-0506A-5 functions across ±5V to ±15V supplies, with on-resistance and leakage specs characterized at ±15V but scalable per Figure 1C. However, the ±44V absolute maximum supply differential must never be exceeded. Derating is required for higher temperatures: at +75°C, maximum continuous supply should remain ≤±13.5V to ensure 150°C junction limit compliance. HI3-0506A-5 remains fully functional down to ±5V, though access time increases to 1.0μs.

What is the purpose of the VREF pin on the HI3-0506A-5?

The VREF pin on HI3-0506A-5 sets the reference for digital input level shifting: when left open, it enables TTL-compatible operation (0.8V/4.0V thresholds); when tied to VAH, it supports logic high levels >6V. This dual-mode flexibility allows HI3-0506A-5 to interface directly with both legacy TTL and modern 5V CMOS controllers without external level translators. VREF has no effect on analog signal path performance.

How does the HI3-0506A-5 behave during power loss?

During power loss, HI3-0506A-5 enters fail-safe mode: all analog inputs present 1kΩ resistance to prevent uncontrolled current flow, and no channel conducts - eliminating risk of back-driving powered downstream circuitry. This behavior is intrinsic to its dielectrically isolated CMOS process and requires no external components. HI3-0506A-5 resumes normal operation within 100ns of supply stabilization, with no initialization sequence needed.
