Product details
Overview
ISL54053IRUZ-T from Intersil is an ultra-low ON-resistance, single-supply SPDT analog switch optimized for battery-powered portable systems. It delivers 0.8Ω rON at +5V, 24ns tON/10ns tOFF, and guaranteed break-before-make switching, enabling high-fidelity signal routing in cellular phone audio paths and ASIC I/O expansion.
For engineers reviewing the ISL54053IRUZ-T datasheet, ISL54053IRUZ-T pinout, ISL54053IRUZ-T application, or ISL54053IRUZ-T equivalent, key selection criteria include supply voltage range (1.8V–5.5V), rON flatness (0.25Ω at +4.5V), ESD robustness (>6kV HBM), and µTDFN package footprint compatibility with space-constrained handheld PCBs.
Technical Context
The ISL54053IRUZ-T implements a committed SPDT topology with one normally open (NO) and one normally closed (NC) channel, configurable as a 2:1 multiplexer. Its submicron CMOS process enables precise rON matching (0.004Ω) and low charge injection (26pC at +4.5V), critical for minimizing signal distortion in audio and sensor front-ends.
It features integrated level-shifting logic compatible with 1.8V CMOS inputs at +3V supply, and internal ESD diodes rated >6kV HBM. The device requires strict supply sequencing-V+ must be applied before any analog or digital signals-to prevent forward-biasing protection diodes and avoid latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON @ +5V | 0.8Ω typical - ensures minimal insertion loss (<0.01dB) in 50Ω RF/audio paths |
| rON flatness | 0.25Ω @ +4.5V - maintains consistent gain across full analog signal range (0V to V+) |
| tON/tOFF | 24ns/10ns @ +4.5V - supports high-speed data switching up to ~190MHz -3dB bandwidth |
| Supply range | +1.8V to +5.5V - enables direct interface with Li-ion battery (3.0–4.2V) and 1.8V/3.3V logic domains |
| ESD rating | >6kV HBM - provides robust handling margin for assembly and end-user environments |
| Leakage current | ±300nA max over temperature - preserves accuracy in high-impedance sensor or medical signal paths |
| Package | 6-lead µTDFN (1.2mm × 1.0mm × 0.5mm) - reduces board area by >60% vs. SOT-23 |
Pinout & Package
ISL54053IRUZ-T is packaged in a 6-lead ultra-thin dual flat no-lead (µTDFN) measuring 1.2mm × 1.0mm × 0.5mm with 0.40mm pitch, RoHS-compliant NiPdAu (e4) termination, and MSL3 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | 1.8V CMOS-compatible logic pin; threshold 0.5V/1.4V at +3V supply |
| 2 (V+) | Positive power supply | Single rail input (1.8V–5.5V); powers internal switches and level shifters |
| 3 (GND) | Ground reference | Return path for analog signals and digital logic; must be connected before V+ |
| 4 (NO) | Normally open analog terminal | Connects to COM only when IN = logic high; used for active-path routing |
| 5 (NC) | Normally closed analog terminal | Connects to COM only when IN = logic low; enables default signal path |
| 6 (COM) | Analog common node | Shared I/O port; bidirectional signal path between NO/NC and external circuitry |
Key Features

FAQ
What is the maximum analog signal voltage range supported by the ISL54053IRUZ-T?
The ISL54053IRUZ-T supports an analog signal range from 0V to V+, where V+ is the positive supply voltage. With a supply range of +1.8V to +5.5V, the analog input/output voltage must remain within this rail-to-rail window. Exceeding V+ or going below GND forward-biases internal ESD diodes, so external clamping may be required in overvoltage scenarios. This behavior is explicitly defined in the Absolute Maximum Ratings table on page 3 of the FN6460 datasheet.
Does the ISL54053IRUZ-T require external pull-up or pull-down resistors on the IN pin?
No, the ISL54053IRUZ-T does not require external pull-up or pull-down resistors on the IN pin. Its digital input is internally biased and fully compatible with 1.8V CMOS logic levels (VIH ≥ 1.4V, VIL ≤ 0.5V at +3V supply). Input current is specified at ±0.1μA over temperature, confirming negligible loading. External resistors are only recommended if overvoltage protection is needed-per Figure 8 in the datasheet-but not for basic logic-level translation or biasing.
Can the ISL54053IRUZ-T operate reliably at 1.8V supply while switching 1.5V analog signals?
Yes, the ISL54053IRUZ-T is fully characterized and guaranteed to operate at +1.8V supply with analog signals up to V+ (i.e., 1.8V). At this voltage, rON is 2.33Ω typical and tON/tOFF are 68ns/45ns-still suitable for audio and low-speed sensor multiplexing. The datasheet's Electrical Specifications – 1.8V Supply section (page 5) confirms functionality across the full -40°C to +85°C range, with all parameters tested or characterized per Notes 10–13.
What is the thermal resistance (θJA) of the ISL54053IRUZ-T in its µTDFN package?
The ISL54053IRUZ-T in the 6-lead µTDFN package has a typical junction-to-ambient thermal resistance (θJA) of 175°C/W, measured on a high thermal conductivity test board in free air (per Tech Brief TB379). This value assumes standard JEDEC layout guidelines; actual θJA in end-user PCBs depends on copper area, via count, and airflow. No θJC is specified for the µTDFN variant-only for the SOT-23 version (120°C/W).
Is the ISL54053IRUZ-T pin-compatible with the NLAS5123?
Yes-the datasheet explicitly states "Drop In replacement for the NLAS5123" in the Features section (page 1). Both devices are 6-pin SPDT analog switches with identical pin functions (IN, V+, GND, NO, NC, COM) and µTDFN/SOT-23 package options. However, the ISL54053IRUZ-T improves upon the NLAS5123 with lower rON (0.8Ω vs. ~1.2Ω at 5V), faster switching (24ns vs. ~35ns tON), and higher ESD rating (>6kV vs. 4kV HBM).
