Product details
Overview
HI3-0548-5 from Intersil is a single 8-channel CMOS analog multiplexer with active overvoltage protection, ±15V analog signal range, 70VP-P fault tolerance, and guaranteed rON matching. It operates in industrial control systems where external sensors feed signals exceeding supply rails without damaging the device or disturbing other channels.
For engineers reviewing the HI3-0548-5 datasheet, HI3-0548-5 pinout, HI3-0548-5 application, or HI3-0548-5 equivalent, key selection criteria include its 16-pin PDIP package, break-before-make switching, 500ns typical access time, and 25pF channel output capacitance - all critical for high-reliability data acquisition in mixed-supply environments.
Technical Context
The HI3-0548-5 implements dielectrically isolated CMOS (CMOS-DI) technology to enable true analog overvoltage protection: input faults up to ±33V induce only 4nA off-leakage while maintaining signal isolation. Its decoder/driver architecture uses level-shifted TTL-compatible address inputs (A0–A2) and an enable pin to select one of eight single-ended analog inputs to a common output.
Protection circuitry includes clamping diodes and 1kΩ series resistance per input under fault conditions, ensuring robustness against short circuits during supply loss. The device requires dual ±15V supplies and supports VREF-open operation, with no internal reference needed for standard use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | Single 8-channel configuration - selects one of eight analog inputs to shared output. |
| Analog Signal Range | ±15V - supports full-rail operation with ±15V dual supplies, enabling direct interfacing with industrial sensor outputs. |
| Overvoltage Tolerance | 70VP-P continuous - withstands sustained analog overvoltages beyond supply rails without latch-up or degradation. |
| Access Time | 500ns typical - ensures fast channel switching for real-time sampling in data acquisition systems. |
| rON Matching | ≤7% ΔrON - guarantees consistent on-resistance across all channels, critical for precision gain-matching in multi-channel instrumentation. |
| Channel Capacitance | 25pF CD(OFF) - low off-capacitance minimizes crosstalk and settling time in high-impedance signal paths. |
| Power Dissipation | 7.5mW typical - enables low-power operation in thermally constrained industrial modules. |
Pinout & Package
HI3-0548-5 is supplied in a 16-lead PDIP (Plastic Dual-In-Line) package per drawing E16.3, RoHS-compliant with Pb-free finish. Pin count, spacing (0.300" wide body), and lead form are standardized for through-hole wave solder assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+V) | Positive Supply | Connects to +15V rail; powers internal logic and analog switches. |
| 2 (IN 1) | Analog Input 1 | First of eight single-ended analog inputs; protected by active clamp circuitry. |
| 3 (IN 2) | Analog Input 2 | Second analog input; identical protection and impedance characteristics as IN 1. |
| 4 (IN 3) | Analog Input 3 | Third analog input; shares same rON and leakage specs across all channels. |
| 5 (IN 4) | Analog Input 4 | Fourth analog input; supports ±15V signal range with no external protection required. |
| 6 (IN 5) | Analog Input 5 | Fifth analog input; maintains ≤7% rON mismatch versus other channels at ±10V. |
| 7 (IN 6) | Analog Input 6 | Sixth analog input; fault-tolerant design prevents channel interaction during overvoltage events. |
| 8 (IN 7) | Analog Input 7 | Seventh analog input; presents 1kΩ resistance when supply is lost, limiting fault current. |
| 9 (IN 8) | Analog Input 8 | Eighth analog input; fully compatible with TTL-level address decoding. |
| 10 (A0) | Address Bit 0 | LSB of 3-bit binary channel select; TTL-compatible (0.8V/4V thresholds). |
| 11 (A1) | Address Bit 1 | Middle bit of channel select; level-shifted internally for reliable decoding across temperature. |
| 12 (A2) | Address Bit 2 | MSB of channel select; enables full 8-channel addressing with EN assertion. |
| 13 (EN) | Enable Input | Active-high digital control; disables all switches when low, reducing leakage and power. |
| 14 (OUT) | Analog Output | Common output node; routed to selected input with break-before-make timing (80ns). |
| 15 (GND) | Ground Reference | Logic and substrate reference; must be connected to system ground for proper level shifting. |
| 16 (−V) | Negative Supply | Connects to −15V rail; completes dual-supply operation and enables negative signal handling. |
Key Features
| Feature | Design Value |
|---|---|
| Active Overvoltage Protection | 70VP-P continuous tolerance with <4nA off-leakage under ±33V fault - eliminates need for external TVS or series resistors. |
| Guaranteed rON Matching | ≤7% max mismatch between any two channels at ±10V - ensures consistent gain and linearity in multi-channel measurement systems. |
| Break-Before-Make Switching | 80ns minimum open interval prevents momentary shorting between channels - critical for avoiding signal transients in precision analog routing. |
| Dielectrically Isolated CMOS | 44V maximum V+–V− rating and 175°C max junction temperature - enables operation in harsh industrial environments with wide supply margins. |
| TTL-Compatible Addressing | A0–A2 and EN accept standard 0.8V/4V logic thresholds without pull-ups - simplifies interface with microcontrollers and FPGAs. |

FAQ
What is the maximum analog input voltage the HI3-0548-5 can safely handle?
The HI3-0548-5 supports a continuous analog signal range of ±15V under normal operation. Under fault conditions, it withstands constant 70VP-P overvoltage (±33V relative to supplies) without damage or signal path disturbance. This is enabled by integrated active clamping and 1kΩ input resistance during supply loss - verified per FN3150 Rev 7.00 Absolute Maximum Ratings and Figure 3 test data.
Does the HI3-0548-5 require an external reference voltage on the VREF pin?
No, the HI3-0548-5 operates with VREF left open for standard TTL-level address inputs (A0–A2, EN). The VREF pin is only required when driving the address inputs from MOS logic with VOH >6V - a condition not applicable to HI3-0548-5's intended use case. Per FN3150 Rev 7.00 Electrical Specifications, VREF = Open is the default test condition for all timing and leakage parameters.
What is the guaranteed rON matching specification for the HI3-0548-5?
The HI3-0548-5 guarantees ΔrON ≤7.0% between any two channels at VOUT = ±10V and IOUT = 100μA, as specified in the FN3150 Rev 7.00 Electrical Specifications table (page 9). This matching is process-controlled and tested across temperature, ensuring consistent channel-to-channel gain in precision measurement applications.
Can the HI3-0548-5 be used with single-supply operation?
No - the HI3-0548-5 requires dual ±15V supplies to operate within datasheet specifications. Its analog signal range, overvoltage protection architecture, and internal level-shifting circuitry are designed exclusively for symmetric bipolar supplies. Attempting single-supply operation violates Absolute Maximum Ratings and will result in undefined behavior or permanent damage.
Is the HI3-0548-5 pin-compatible with other devices in the HI-546/547/548/549 family?
Yes - the HI3-0548-5 shares identical pinout and function with HI-548 variants in the same 16-lead PDIP package (E16.3), including HI3-548-5Z and HI9P0548-5Z. However, it is not pin-compatible with HI-546 (28-pin), HI-547 (28-pin differential), or HI-549 (16-pin differential) due to differing channel count, topology, and pin assignments - confirmed by Pinouts on pages 3–4 of FN3150 Rev 7.00.
