Product details
Overview
ISL84714IHZ-T7A from Intersil is an ultra-low ON-resistance, single-pole/double-throw (SPDT) analog switch designed for bidirectional signal routing in battery-powered systems. It operates from a single +1.65V to +3.6V supply, delivers 0.44Ω rON at +2.7V, achieves 7.5ns tON/2.9ns tOFF, and is housed in a space-saving 6-lead SC70 package - enabling high-fidelity audio/video switching and ASIC I/O expansion in mobile phones.
For engineers reviewing the ISL84714IHZ-T7A datasheet, ISL84714IHZ-T7A pinout, ISL84714IHZ-T7A application, or ISL84714IHZ-T7A equivalent, key selection criteria include guaranteed break-before-make timing, 1.8V CMOS logic compatibility at 3V supply, sub-1Ω rON across 1.8V–3.6V operation, <20pC charge injection, and >6kV HBM ESD rating - all validated for portable equipment signal integrity and low-power reliability.
Technical Context
The ISL84714IHZ-T7A implements a committed SPDT architecture with one normally open (NO) and one normally closed (NC) channel, supporting both analog multiplexing and signal path selection. Its sub-1Ω ON-resistance is maintained over full analog signal range (0V to V+), with rON flatness of only 0.06Ω at +2.7V - minimizing harmonic distortion and insertion loss in audio paths.
Internal level shifters translate 1.8V-compatible digital inputs (VINL ≤ 0.5V, VINH ≥ 1.4V at 3V supply) into full-rail gate drive for the CMOS transmission gates. The device features integrated ESD protection diodes (HBM >6kV) on all analog pins and guarantees break-before-make switching with tD = 1–4ns, preventing momentary short-circuits during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON (V+ = +2.7V) | 0.44Ω typical - enables <0.1% signal attenuation in 50Ω systems and preserves SNR in high-fidelity audio routing |
| tON/tOFF (+2.7V) | 7.5ns/2.9ns - supports fast channel switching in multi-signal test equipment and real-time sensor muxing |
| Supply Range | +1.65V to +3.6V - allows direct integration with Li-ion (3.0–3.6V) and dual-cell alkaline (1.8–3.0V) battery rails without regulation |
| Charge Injection | 20pC max - limits voltage glitch on high-impedance nodes (e.g., ADC inputs), reducing need for external settling compensation |
| OFF Isolation (1MHz) | −50dB - suppresses crosstalk between adjacent channels in compact handheld PCB layouts |
| ESD Rating (HBM) | >6kV - meets IEC 61000-4-2 Level 4 for robust handling in consumer device assembly and field use |
| Logic Compatibility | 1.8V CMOS at +3V supply - interfaces directly with modern baseband processors and application SoCs without level shifters |
Pinout & Package
ISL84714IHZ-T7A is packaged in a 6-lead SC70 (P6.049) surface-mount package measuring 2.0mm × 1.25mm × 0.9mm (max), optimized for high-density portable PCBs. The package is RoHS-compliant with 100% matte tin (e3) termination and MSL3 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital Control Input | Accepts 1.8V CMOS logic; drives internal level shifter to control NO/NC switch states; logic "0" ≤ 0.5V, logic "1" ≥ 1.4V at 3V supply |
| 2 (V+) | Positive Supply Rail | Single power input for analog switches and logic core; supports 1.65V–3.6V operation; absolute max 4.8V |
| 3 (GND) | Ground Reference | Common return for analog signal paths and digital logic; must be low-impedance to minimize ground bounce during fast switching |
| 4 (NO) | Normally Open Analog Terminal | Connects to COM only when IN = logic "1"; used as secondary signal path in 2:1 mux configurations |
| 5 (NC) | Normally Closed Analog Terminal | Connects to COM when IN = logic "0"; provides default signal path with guaranteed break-before-make transition to NO |
| 6 (COM) | Analog Switch Common Pin | Bidirectional signal port shared between NO and NC; supports full rail-to-rail analog swing (0V to V+) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low rON flatness | 0.06Ω at +2.7V - ensures consistent gain and minimal THD (<0.006%) across full analog input range in audio applications |
| Guaranteed break-before-make | 1–4ns delay - eliminates signal shorting during switching, critical for protecting sensitive downstream circuitry like ADC front-ends |
| rON matching between channels | 0.005Ω typical - enables precise differential signal routing and matched-path performance in instrumentation mux designs |
| Low leakage current | ±10nA max (full temp range) - prevents DC offset accumulation in high-impedance sensor interfaces and medical electrode circuits |
| SC70 footprint | 2.0mm × 1.25mm - reduces board area by >50% vs. comparable SOT-23 switches, easing layout in space-constrained mobile modules |

FAQ
What is the maximum supply voltage rating for the ISL84714IHZ-T7A?
The ISL84714IHZ-T7A has an absolute maximum V+ to GND rating of 4.8V. While its operational supply range is specified from +1.65V to +3.6V, this 4.8V headroom accommodates transient overshoot and 10% tolerance on nominal 3.6V supplies - ensuring robustness in noisy battery-fed systems. Exceeding 4.8V risks permanent damage to internal ESD diodes and CMOS transmission gates.
Does the ISL84714IHZ-T7A support rail-to-rail analog signal switching?
Yes, the ISL84714IHZ-T7A supports full rail-to-rail analog signal switching across its entire specified supply range. The analog signal range (VANALOG) extends from 0V to V+, allowing signals such as audio waveforms, sensor outputs, or video sync pulses to pass unclamped - provided input voltages remain within the absolute maximum ratings (−0.3V to V+ + 0.3V) to avoid forward-biasing internal ESD diodes.
Is the ISL84714IHZ-T7A pin-compatible with the MAX4714?
Yes, the ISL84714IHZ-T7A is a documented drop-in replacement for the MAX4714 in the SC70-6 package. Both share identical pinout (IN, V+, GND, NO, NC, COM), electrical specifications (rON, tON/tOFF, logic thresholds), and thermal characteristics. This compatibility is explicitly stated in the ISL84714 datasheet Feature list and confirmed by matching package drawings (P6.049) and truth tables.
What is the typical charge injection value of the ISL84714IHZ-T7A, and why does it matter?
The ISL84714IHZ-T7A exhibits 20pC typical charge injection at +3V supply. This parameter quantifies the net charge transferred to the COM node during switching, which can induce voltage glitches on high-impedance nodes (e.g., ADC sample capacitors or op-amp inputs). Keeping charge injection below 25pC enables reliable sampling without added settling time or external compensation networks - a key advantage in precision data acquisition systems.
Can the ISL84714IHZ-T7A operate from a 1.8V supply, and how does performance change?
Yes, the ISL84714IHZ-T7A is fully specified for operation down to +1.65V, including at +1.8V. At this supply, rON increases to 0.75Ω (vs. 0.44Ω at +2.7V), tON/tOFF slow to 15.6ns/4.5ns, and logic thresholds adjust to VINL ≤ 0.4V / VINH ≥ 1.0V. These trade-offs are acceptable for ultra-low-power applications like hearing aids or wearables where battery life outweighs speed or conduction loss.
