Product details
Overview
ISL55110IVZ-T7A from Renesas Electronics is a dual high-speed MOSFET driver with in-phase outputs, designed for precise pulse generation and buffering in demanding imaging and timing systems. It delivers 3.5A peak output current, 1.5ns rise/fall times (100pF), 6ns minimum pulse width, and operates across 5V–13.2V driver rail (VH) and 2.7V–5.5V logic supply (VDD), supporting ultrasound transducer drive and CCD array horizontal scanning.
For engineers reviewing the ISL55110IVZ-T7A datasheet, ISL55110IVZ-T7A pinout, ISL55110IVZ-T7A application, or ISL55110IVZ-T7A equivalent, key selection criteria include verified in-phase dual-channel timing skew (<0.5ns), QFN/TSSOP package compatibility, power-down mode (12µA IDD-PDN), and 3.3V/5V logic interface with tightly controlled input thresholds (1.12–1.52V).
Technical Context
The ISL55110IVZ-T7A implements two independent CMOS output stages, each sourcing/sinking up to 3.5A peak into capacitive loads, with rail-to-rail swing (within 30mV of VH/GND) and low 3Ω typical rDS(on). Its input stage features hysteresis (0.2V) and logic-compatible thresholds to suppress pulse-width distortion from slow input edges.
It supports dual supply domains: VDD powers logic circuitry (2.7V–5.5V), while VH sets the high-side output rail (5V–13.2V); thermal design must account for θJA = 140°C/W in the 8-lead TSSOP package, requiring careful PCB layout for ground isolation and VH bypassing (4.7µF + 0.1µF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Configuration | In-phase dual drivers (OA and OB follow IN-A and IN-B without inversion) |
| Peak Output Current | 3.5A - enables fast charging of 330pF loads to 12V in <3.0ns over full temperature range |
| Rise/Fall Time | 1.2ns/1.4ns @ 100pF - ensures sub-nanosecond edge fidelity for high-frequency clock and imaging timing |
| Min Pulse Width | 6ns - supports ultrasonic burst generation and high-resolution CCD pixel addressing |
| Propagation Skew | <0.5ns - guarantees matched channel timing critical for synchronized multi-element drive |
| Power-down Current | 12µA IDD-PDN - reduces standby power in portable ultrasound and battery-operated imaging systems |
| Logic Compatibility | 3.3V/5V CMOS/TTL - eliminates level-shifter requirements in mixed-voltage FPGA or microcontroller interfaces |
Pinout & Package
ISL55110IVZ-T7A uses an 8-lead TSSOP package (M8.173) with exposed pad not present; GND (Pin 8) serves as common return for both VH and VDD supplies, and thermal performance relies on PCB copper area under the package body.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Logic supply input (2.7V–5.5V); powers internal buffers and control logic |
| 2 | PD | Active-high power-down enable; places outputs in high-impedance state when asserted |
| 3 | IN-B | Non-inverting logic input controlling OB output; matches IN-A phase per ISL55110 specification |
| 4 | IN-A | Non-inverting logic input controlling OA output; accepts 3.3V/5V logic with hysteresis |
| 5 | OB | Driver output referenced to GND; swings rail-to-rail between GND and VH |
| 6 | VH | High-side driver supply (5V–13.2V); sets output voltage swing ceiling and current capability |
| 7 | OA | Driver output referenced to GND; in-phase with IN-A, identical timing to OB |
| 8 | GND | Common return for VDD, VH, and output currents; electrically tied to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| In-phase dual outputs | Enables synchronous drive of parallel MOSFETs or matched load banks without external signal inversion |
| Sub-nanosecond channel skew | <0.5ns tSkewR/tSkewF ensures time-aligned pulses essential for echo-time precision in ultrasound beamforming |
| Wide VH operating range | 5V–13.2V support allows direct integration with diverse HV bias rails in piezo and CCD applications |
| Tightly controlled input thresholds | VIX_LH = 1.42V typ, VIX_HL = 1.22V typ minimizes pulse-width jitter from input slew rate variations |
| Integrated power-down mode | Reduces total supply current to 12µA (IDD-PDN) during idle periods, extending battery life in portable systems |
Applications

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 |
|---|---|---|---|
| ISL55110IRZ-T7A | Same electrical specs but in 16-lead QFN (4×4mm) with ENABLE pin and exposed thermal pad; θJA = 45°C/W vs. 140°C/W for TSSOP | Better thermal performance required for continuous 50MHz+ operation or higher VH voltages (>10V) | Select ISL55110IRZ-T7A when board space permits QFN and thermal management demands lower junction temperature rise. |
| LM5112MMX/NOPB | Single-channel, 5A peak, 10ns min pulse width, no power-down mode; requires external inverters for dual in-phase outputs | Lacks integrated dual-channel synchronization and low-power standby; suited for discrete high-current single-load drive | Choose LM5112MMX/NOPB only when single-output flexibility, higher peak current, or cost-driven BOM simplification outweighs need for matched dual timing. |
Compared with ISL55110IRZ-T7A, the ISL55110IVZ-T7A trades thermal headroom for smaller footprint and no ENABLE pin-ideal for space-constrained TSSOP layouts where 140°C/W θJA suffices. Versus LM5112MMX/NOPB, it delivers guaranteed dual-channel timing alignment and ultra-low standby power, eliminating external logic and reducing system-level timing uncertainty.

FAQ
What is the maximum allowable VH voltage for ISL55110IVZ-T7A?
The absolute maximum VH voltage for ISL55110IVZ-T7A is 14.0V, but the recommended operating range is 5V to 13.2V. Operation at 13.2V maintains full 3.5A peak output current and 1.5ns edge performance while staying within safe SOA limits across -40°C to +85°C ambient. Exceeding 13.2V may degrade reliability or trigger overvoltage protection in downstream circuits.
Does ISL55110IVZ-T7A support 3.3V logic inputs?
Yes, ISL55110IVZ-T7A fully supports 3.3V logic inputs: its VIH threshold is 2.0V min and VIL is 0.8V max, with hysteresis of 0.2V. Input thresholds remain stable across VDD = 2.7V–5.5V, ensuring reliable switching even with marginal 3.3V CMOS drive. No external level shifting is needed when interfacing with 3.3V FPGAs or microcontrollers.
How does the power-down mode function on ISL55110IVZ-T7A?
When PD (Pin 2) is driven high, ISL55110IVZ-T7A enters power-down mode: logic supply current drops to 12µA (IDD-PDN), driver supply current falls to 2.5µA (IH_PDN), and both OA and OB outputs go high-impedance. This state persists until PD returns low, with 650ns wake-up delay (PDEN). The feature is ideal for duty-cycled ultrasound bursts or intermittent CCD scanning.
Can ISL55110IVZ-T7A drive a 680pF load with sub-10ns rise time?
Yes-ISL55110IVZ-T7A achieves 6.2ns rise time (tR) and 6.9ns fall time (tF) into a 1nF load, and 12.8ns/12.5ns into 680pF (per Figure 3). At VH = 12V and VDD = 3.6V, these values are guaranteed over temperature. For 680pF, the device remains well within its 70MHz FMAX limit and maintains <0.5ns channel skew, making it suitable for high-capacitance CCD row drivers.
Is there an ENABLE pin on the ISL55110IVZ-T7A package?
No, the ISL55110IVZ-T7A (8-lead TSSOP) does not include an ENABLE pin. That function is exclusive to the 16-lead QFN variants (e.g., ISL55110IRZ-T7A), where ENABLE provides tri-state control independent of PD. On ISL55110IVZ-T7A, output enable/disable is managed solely via the PD pin; tying PD high disables both outputs simultaneously with no intermediate tri-state option.
