Product details
Overview
ISL55111IVZ from Renesas Electronics is a dual high-speed anti-phase MOSFET driver optimized for accurate pulse generation and low-skew buffering in CCD imaging, ultrasound transmit circuits, and clock distribution systems. It delivers 3.5A peak output current, 1.5ns rise/fall times into 100pF, 6ns minimum pulse width, and operates with VH rail from 5V to 13.2V and logic supply VDD from 2.7V to 5.5V.
For engineers reviewing the ISL55111IVZ datasheet, ISL55111IVZ pinout, ISL55111IVZ application, or ISL55111IVZ equivalent, this page provides verified functional identity, confirmed 8-lead TSSOP package mapping, validated anti-phase output behavior, real-world timing skew data (<0.5ns), and two technically documented alternative drivers for CCD and ultrasound system design.
Technical Context
The ISL55111IVZ implements two independent CMOS output stages driven by tightly controlled input thresholds (VIX_LH = 1.42V typ, VIX_HL = 1.22V typ) to minimize input-edge-rate sensitivity on output pulse width. Its anti-phase architecture ensures complementary OA/OB outputs - IN-B is inverted relative to IN-A - enabling push-pull drive without external logic.
Each channel features low rDS(on) of 3–6Ω, rail-to-rail swing (within 30mV of VH/GND), and integrated power-down (PD) control reducing logic supply current to 12µA. The device lacks ENABLE functionality in TSSOP packaging, distinguishing it from the QFN variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VH Supply Range | 5V to 13.2V - sets maximum output voltage swing and directly determines slew rate and drive strength into capacitive loads. |
| Peak Output Current | 3.5A - enables fast charging of large CCD line capacitances (e.g., 330pF to 12V in <3ns) without waveform degradation. |
| Rise/Fall Time | 1.2ns/1.4ns @ 100pF - guarantees sub-nanosecond edge fidelity critical for time-of-flight ultrasound and high-resolution imaging timing. |
| Channel Skew | <0.5ns - ensures precise inter-channel timing alignment required for differential clocking and phased array signal generation. |
| Min Pulse Width | 6ns - supports ultrasonic burst frequencies up to ~70MHz and high-speed horizontal CCD scanning. |
| Logic Compatibility | 3.3V/5V - allows direct interface with FPGA I/O banks, microcontroller GPIOs, and ASIC control logic without level shifters. |
| Operating Temp | -40°C to +85°C - qualified for industrial and medical equipment environments including portable ultrasound systems. |
Pinout & Package
ISL55111IVZ is packaged in an 8-lead TSSOP (M8.173) with exposed thermal pad connected internally to GND. Pin 11 (GND) is electrically tied to the EP; PCB layout must connect EP to ground plane per thermal guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Logic power supply | Supplies internal buffer and control logic; must be decoupled with 0.1µF + 4.7µF near pin. |
| PD (Pin 2) | Power-down enable | Active-high signal placing outputs in high-impedance state; reduces IDD to 12µA for standby operation. |
| IN-B (Pin 3) | Inverted logic input | Drives OB output with inversion - defines anti-phase relationship vs IN-A; requires <2ns input edge rates. |
| IN-A (Pin 4) | Non-inverted logic input | Drives OA output directly; enables independent timing control of both channels for custom phasing. |
| OB (Pin 5) | Anti-phase driver output | Swings rail-to-rail between GND and VH; complements OA for push-pull gate drive or differential signaling. |
| VH (Pin 6) | High-side driver supply | Defines output voltage ceiling; must be sequenced after VDD and bypassed independently for low-noise switching. |
| OA (Pin 7) | In-phase driver output | Swings rail-to-rail between GND and VH; synchronized with IN-A; used for single-ended clock or gate drive. |
| GND (Pin 8) | Common return | Reference for both VH and VDD supplies; shared path for input and output currents - requires low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Anti-phase dual outputs | IN-B inversion enables true complementary drive without external inverters - reduces component count and propagation delay in CCD row drivers. |
| Tightly controlled input thresholds | VIX_LH/VIX_HL hysteresis of 0.2V minimizes pulse-width distortion from slow or noisy logic edges - critical for ultrasound burst timing accuracy. |
| Low-output impedance | rDS(on) = 3–6Ω ensures minimal voltage drop under 3.5A peak load - maintains full VH rail utilization across temperature and supply variations. |
| Sub-nanosecond channel skew | tSkewR/tSkewF <0.5ns guarantees matched propagation delays - essential for time-critical applications like phased-array beamforming. |
| Integrated power-down mode | Reduces total supply current to 12µA (IDD-PDN) + 2.5µA (IH_PDN) - extends battery life in portable medical imaging devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL55111IRZ | 16-lead QFN package with ENABLE pin; identical electrical specs and anti-phase function. | Supports high-speed enable/disable control via ENABLE pin; better thermal performance (θJA = 45°C/W vs 140°C/W). | Select IRZ when board space permits QFN and active output gating is required; IVZ preferred for legacy TSSOP footprints. |
| LM5112MMX/NOPB | Single-channel, 5A peak driver; no built-in anti-phase logic; requires external inverter for complementary outputs. | Lacks integrated dual anti-phase architecture; higher peak current but no channel-to-channel timing matching. | Choose LM5112MMX/NOPB only when discrete channel control and >3.5A drive are mandatory; not drop-in for ISL55111IVZ's dual anti-phase use cases. |
Compared with ISL55111IRZ, the ISL55111IVZ trades thermal efficiency and ENABLE functionality for TSSOP compatibility and simpler layout; versus LM5112MMX/NOPB, it delivers guaranteed sub-0.5ns skew and integrated anti-phase logic - eliminating external components and timing uncertainty in CCD and ultrasound timing paths.

FAQ
What is the key functional difference between ISL55111IVZ and ISL55110IVZ?
The ISL55111IVZ features anti-phase outputs - IN-B drives OB with inversion relative to IN-A - while the ISL55110IVZ provides in-phase outputs on both channels. This makes ISL55111IVZ ideal for push-pull configurations in ultrasound and CCD drivers, whereas ISL55110IVZ suits parallel or synchronous drive applications. Both share identical pinout, package, and electrical specs except output phasing.
Does ISL55111IVZ support ENABLE functionality like the QFN version?
No. The ISL55111IVZ in 8-lead TSSOP packaging does not include an ENABLE pin; that feature is exclusive to the 16-lead QFN variants (e.g., ISL55111IRZ). In the ISL55111IVZ, output control is managed solely via IN-A/IN-B inputs and the PD (power-down) pin - which places both outputs in high-impedance state when asserted high.
What is the maximum load capacitance ISL55111IVZ can drive while maintaining 6ns minimum pulse width?
At VH = 12V and TA = +25°C, the ISL55111IVZ maintains ≤6ns pulse width up to 330pF load capacitance, as verified by typical performance curves (Figures 22–23 show tR/tF ≤3ns at 330pF). Beyond 330pF, pulse width increases due to RC time constant effects; for 680pF loads, minimum pulse width exceeds 8ns per datasheet propagation delay data.
How does the ISL55111IVZ handle ground noise between logic and driver sections?
The ISL55111IVZ shares a single GND pin (Pin 8) for both VDD logic and VH driver return paths. Because IN-B is inverted, any ground inductance creates negative feedback that degrades skew and edge fidelity. Renesas explicitly recommends separate ground returns for input and output circuits - routed as close to the ISL55111IVZ as possible - or use of a solid ground plane to minimize common-impedance coupling.
Is ISL55111IVZ compatible with 2.5V logic inputs?
No. ISL55111IVZ logic inputs require VDD between 2.7V and 5.5V, and its input thresholds (VIX_LH = 1.42V typ, VIX_HL = 1.22V typ) are optimized for 3.3V/5V systems. A 2.5V logic source may fail to reliably exceed VIX_LH, causing erratic output behavior. For 2.5V interfaces, level-shifting circuitry or a different driver family (e.g., Renesas ISL65xx series) is required.
