Product details
Overview
ISL84053IAZ from Intersil is a triple single-pole/double-throw (SPDT) analog switch configured for 2-to-1 multiplexing, operating from single +2V to +12V or dual ±2V to ±6V supplies. It delivers 60Ω ON-resistance at ±5V, 90ns/60ns turn-on/turn-off times at +5V, 2pC charge injection, and 5nA max off-leakage at +85°C - enabling precision signal routing in portable medical ultrasound front-ends.
For engineers reviewing the ISL84053IAZ datasheet, ISL84053IAZ pinout, ISL84053IAZ application, or ISL84053IAZ equivalent, key selection criteria include rail-to-rail analog signal handling, break-before-make switching, TTL/CMOS logic compatibility at 3.3V/5V, and guaranteed 125Ω rON max at +5V supply.
Technical Context
The ISL84053IAZ implements three independent SPDT switches with shared digital control: ADDA, ADDB, ADDC select NOA/NCA, NOB/NCB, NOC/NCC paths respectively, while INH globally disables all channels. Each switch features CMOS transmission gates with level-shifted gate drive referenced to V+ and V−, supporting true bidirectional analog signal flow without GND reference.
Its architecture enforces break-before-make timing (≤30ns at +5V) to prevent momentary shorting during state transitions, and integrates ESD protection diodes on all analog pins (V+ and V− referenced), requiring proper supply sequencing to avoid forward biasing - critical for battery-powered systems where V+ may ramp before analog inputs stabilize.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Triple SPDT analog switch for 2-to-1 multiplexing per channel |
| ON-resistance (rON) | 60Ω max at ±5V supply - ensures minimal signal attenuation in precision gain-switching networks |
| Switching speed | 90ns tON / 60ns tOFF at +5V - supports high-speed data acquisition sampling rates up to ~5 MHz |
| Charge injection | 2pC typical - limits voltage glitch in sample-and-hold circuits using 1nF hold capacitors |
| Off-leakage current | 5nA max at +85°C with ±5V supply - preserves accuracy in high-impedance sensor interfaces |
| Supply range | +2V to +12V single or ±2V to ±6V dual - enables direct integration with 3.3V, 5V, and ±5V system rails |
| Logic compatibility | 0.8V–2.4V thresholds - interoperates with 3.3V and 5V TTL/CMOS controllers without level shifters |
Pinout & Package
ISL84053IAZ is housed in a 16-lead QSOP package (Pb-free, RoHS compliant), with 1.27mm pitch and 5.0mm × 4.0mm body size. Pin 1 is top-left corner when notch faces up; pin numbering follows standard counter-clockwise sequence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Bias source for internal CMOS switches and logic; sets upper analog signal limit (V+ − 0.3V) |
| V− | Negative power supply input | Reference for bipolar operation; connect to GND for single-supply use |
| GND | Ground connection | Logic ground reference only - no analog signal path connection |
| INH | Inhibit control input | Active-high global disable: logic high opens all three SPDT paths simultaneously |
| ADDA, ADDB, ADDC | Address select inputs | Binary control lines selecting NOA/NCA, NOB/NCB, NOC/NCC states respectively |
| COMA, COMB, COMC | Common terminals | Center poles of each SPDT switch - connected to load or signal destination |
| NOA, NOB, NOC | Normally open terminals | Outputs closed to COMx when corresponding ADDx = 1 |
| NCA, NCB, NCC | Normally closed terminals | Outputs closed to COMx when corresponding ADDx = 0 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4053ESE+ | Same triple SPDT function, 60Ω rON at ±5V, but 125ns/75ns tON/tOFF at +5V - slower switching than ISL84053IAZ | Higher propagation delay limits use in >3MHz multiplexing; identical pinout and supply range | Select MAX4053ESE+ only if timing margin allows 35ns longer tON and layout reuse is critical |
| 74HC4053PW,118 | CMOS-based triple SPDT with 120Ω rON at +5V, no dual-supply support - operates +2V to +10V only | Lacks ± supply capability and rail-to-rail analog range; higher rON increases THD in audio paths | Choose 74HC4053PW,118 for cost-sensitive single-supply industrial controls where ±5V operation is unnecessary |
Compared with MAX4053ESE+ and 74HC4053PW,118, the ISL84053IAZ provides superior high-speed performance (90ns tON), true bipolar operation, and lower charge injection - making it optimal for precision medical and test equipment demanding sub-100ns switching and ±5V signal fidelity.

FAQ
What is the maximum supply voltage rating for ISL84053IAZ?
The ISL84053IAZ has an absolute maximum V+ to V− rating of 15V, supporting operation up to ±6V dual supply or +12V single supply. Exceeding these limits risks permanent damage due to internal ESD diode conduction - always apply V+ and V− before analog signals per datasheet sequencing guidelines.
Does ISL84053IAZ support rail-to-rail analog signal switching?
Yes, ISL84053IAZ supports rail-to-rail analog signal switching from V− to V+, including operation with V− tied to GND in single-supply mode. This enables full utilization of ±5V op-amp outputs or 0–5V DAC outputs without signal clipping or distortion.
How does the INH pin function on ISL84053IAZ?
The INH pin on ISL84053IAZ is an active-high inhibit control: when pulled to V+, all three SPDT switches open regardless of ADDA/ADDB/ADDC states. When tied to GND, normal address-controlled switching resumes - enabling global channel disable for system-level power gating or fault isolation.
What is the typical charge injection value for ISL84053IAZ and its impact on circuit design?
ISL84053IAZ specifies 2pC typical charge injection, measured with 1nF load capacitance. In sample-and-hold circuits, this induces ≤2mV glitch on a 1nF capacitor - requiring careful attention to hold capacitor sizing and settling time in 12-bit+ precision applications.
Is ISL84053IAZ pin-compatible with industry-standard alternatives?
Yes, ISL84053IAZ is pin-compatible with MAX4053 and 74HC4053 devices in 16-pin SOIC, QSOP, and TSSOP packages. The pin mapping for COMx, NOx, NCx, ADDx, INH, V+, V−, and GND matches exactly - enabling drop-in replacement where timing and leakage specs meet design requirements.
