Product details
Overview
ISL43113IHZ-T from Intersil is a low-voltage, dual-supply, single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, operating from ±1.5V to ±6V supplies. It delivers 15Ω on-resistance at ±4.5V, 42ns turn-on time, 25ns turn-off time, 7pC charge injection, and sub-nanoamp leakage (5nA max off-leakage at 85°C), enabling precision signal routing in battery-powered portable instrumentation.
For engineers reviewing the ISL43113IHZ-T datasheet, ISL43113IHZ-T pinout, ISL43113IHZ-T application, or ISL43113IHZ-T equivalent, key selection criteria include NC logic behavior, SOT-23 package compatibility, break-before-make timing at ±5V, rON flatness ≤8Ω over full signal range, and ESD robustness (>2000V per MIL-STD-3015.7).
Technical Context
The ISL43113IHZ-T implements a CMOS-based SPST switch architecture with dedicated V+ and V− supply pins-no ground reference-enabling true bipolar analog signal handling from −6V to +6V. Its internal level shifter translates CMOS-compatible logic inputs into rail-swing gate drive for the analog switch FETs.
Break-before-make operation is guaranteed at ±5V supplies, while leakage currents remain below 5nA across −40°C to +85°C. The device avoids single-supply use by design; its input thresholds track V+ (VINH ≥ V+ − 1.5V, VINL ≤ V+ − 3.5V at ±5V), ensuring reliable switching without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Normally closed (NC): conducts when logic input = 0, opens when logic input = 1 |
| rON (±4.5V) | 15Ω typical - enables <1% gain error in 1kΩ impedance paths at mid-scale |
| rON flatness | ≤8Ω over full analog range - preserves linearity in audio, sensor, and DAC output switching |
| tON/tOFF | 42ns/25ns at ±4.5V - supports >10MHz multiplexed sampling without settling distortion |
| Charge injection | 7pC typical - limits voltage glitch to <7mV on 1nF hold capacitors in sample-and-hold circuits |
| Off-leakage (85°C) | 5nA max - ensures <1µV drift/hour in high-impedance medical front-ends (e.g., ECG amplifiers) |
| ESD rating | >2000V HBM - withstands handling in uncontrolled assembly environments without guard rings |
Pinout & Package
ISL43113IHZ-T uses the 5-lead SOT-23 package (JEDEC MO-178AA, Intersil P5.064), with exposed pad omitted and thermal resistance θJA = 225°C/W. Pin 1 is marked via bottom-side laser marking "113Z".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | CMOS-compatible; switches NC path at logic 0 (≤1.5V @ ±5V), open at logic 1 (≥3.5V) |
| 2 (V+) | Positive supply rail | Accepts +1.5V to +6V; powers internal logic and switch gates; must be applied before signals |
| 3 (COM) | Analog common terminal | Current path shared between NC and system load; supports full rail-to-rail analog swing (V− to V+) |
| 4 (V−) | Negative supply rail | Accepts −1.5V to −6V; completes switch bias; reverse ESD diodes clamp signals to V−/V+ |
| 5 (NC) | Analog normally closed terminal | Conducts to COM when IN = 0; disconnects when IN = 1; no internal connection to NO or other pins |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | Guaranteed at ±5V supply - prevents momentary short-circuits during channel switching in multiplexer designs |
| rON flatness ≤8Ω | Maintains <0.5% THD in audio paths and <0.1% nonlinearity in precision sensor interfaces across full input range |
| Sub-nanoamp leakage | 5nA max off-leakage at 85°C - eliminates measurable drift in >10MΩ biomedical amplifier feedback networks |
| 2000V HBM ESD protection | Eliminates need for external TVS diodes in handheld medical and test equipment PCB layouts |
| ±1.5V minimum supply | Enables direct integration with Li-ion battery systems (2.7–4.2V) using split-rail generation, reducing BOM count |
Applications
| Portable Medical Monitoring | High-Fidelity Audio Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL43113IBZ-T | Same silicon die, but in 8-lead SOIC (M8.15) package - larger footprint, lower θJA (170°C/W), no bottom marking | Preferred for prototyping or high-reliability industrial PCBs where thermal margin >50°C required | Select ISL43113IBZ-T when board space allows and thermal performance outweighs size constraints. |
| MAX4613EUT+T | NC SPST switch in SOT-23-6; ±5V only; 35Ω rON; 60ns/30ns switching; 25pC charge injection | Suitable for cost-sensitive, non-precision applications where 15Ω rON and 7pC are not required | Choose MAX4613EUT+T only if ±5V supply is fixed and signal fidelity requirements permit higher rON and charge injection. |
Compared with ISL43113IBZ-T, the ISL43113IHZ-T saves >60% board area with identical electrical performance but higher thermal resistance; versus MAX4613EUT+T, it delivers 2.3× lower rON, 3.6× less charge injection, and dual-supply flexibility down to ±1.5V-critical for ultra-low-power portable designs.

FAQ
What is the logic behavior of the ISL43113IHZ-T?
The ISL43113IHZ-T is a normally closed (NC) analog switch: it conducts between COM and NC terminals when the digital input (IN) is logic low (≤1.5V at ±5V supply), and opens the path when IN is logic high (≥3.5V). This behavior is confirmed in the truth table on page 2 of FN6029 Rev 3.00 and applies identically to the ISL43113IHZ-T variant.
Does the ISL43113IHZ-T support single-supply operation?
No-the ISL43113IHZ-T requires dual supplies (V+ and V−) and is not rated for single-supply use. The datasheet explicitly states "This family of switches is not recommended for single supply applications" (page 8), and the internal architecture relies on symmetric or asymmetric bipolar rails to bias the analog FETs and level-shift logic. For single-supply alternatives, consult the ISL43110/ISL43111 datasheet.
What is the maximum allowable supply voltage for the ISL43113IHZ-T?
The absolute maximum V+ to V− differential is 15V, with individual rails rated from −0.3V to +15V referenced to each other. However, the functional operating range is ±1.5V to ±6V (i.e., 3V to 12V total span), as specified in the Power Supply Characteristics table (page 4). Exceeding ±6V risks violating the guaranteed rON, leakage, and timing specs-even if within absolute maximum ratings.
How is the ISL43113IHZ-T protected against ESD events?
The ISL43113IHZ-T incorporates internal ESD protection diodes from every I/O pin (IN, COM, NC, V+, V−) to both V+ and V− rails, rated to >2000V per MIL-STD-883 Method 3015.7 (page 4). This eliminates the need for external ESD components in most handheld applications, provided supply sequencing rules (V± applied before signals) are followed to avoid forward-biasing the diodes.
Can the ISL43113IHZ-T be used in high-frequency signal paths?
Yes-the ISL43113IHZ-T delivers −3dB bandwidth near 400MHz in 50Ω systems (Figure 15, page 10), with >90dB off-isolation at 100kHz and >50dB at 10MHz. Its 13pF off-capacitance and 30pF on-capacitance minimize loading in RF sampling and video switching, though layout-dependent parasitics dominate above 50MHz. Performance is validated across ±1.5V to ±5.5V supplies.
