Renesas ISL24010IVZ-T

Overview

ISL24010IVZ-T from Intersil is an octal high-voltage TFT-LCD logic driver and voltage level shifter with +40V and -20V (momentary absolute max) output swing, 150ns/210ns rise/fall times, 250ns propagation delay, and 3000pF load drive capability in 500ns. It operates across -40°C to +85°C and drives row/column lines in active-matrix LCD panels.

For engineers reviewing the ISL24010IVZ-T datasheet, ISL24010IVZ-T pinout, ISL24010IVZ-T application, or ISL24010IVZ-T equivalent, this page delivers verified electrical specs, TSSOP-20 terminal mapping, real-world timing behavior under 100–3300pF loads, supply sequencing constraints (VON2 ≥ VON1), and flicker-reduction implementation guidance for TFT-LCD timing control systems.

Technical Context

The ISL24010IVZ-T uses Intersil's monolithic high-voltage bipolar process to support dual positive supplies (VON1: +10V to +40V; VON2: ≥ VON1, +10V to +40V) and one negative supply (VOFF: -5V to -20V). Outputs 1–6 connect to VON1/VOFF; outputs 7–8 connect to VON2/VOFF - enabling independent slicing control for flicker reduction and auxiliary supply management.

It features latch-up-proof DI process isolation, ESD protection with dV/dt-triggered clamp (10V/µs max slew rate), and rail-to-rail CMOS-compatible inputs (-0.5V to 5.5V). Unused inputs must be grounded to prevent oscillation and thermal runaway, and no internal current limiting requires external output current restriction to <80mA.

FAQ

What is the maximum allowable supply turn-on slew rate for ISL24010IVZ-T?

The ISL24010IVZ-T incorporates a dV/dt-triggered ESD clamp that activates if any supply ramp exceeds 10V/µs. Exceeding this rate causes high-current conduction through the clamp, risking device damage. To comply, use RC filtering or controlled DC/DC startup sequencing - especially critical for VON1, VON2, and VOFF rails in hot-plug or unregulated power environments. Always verify ramp rates with oscilloscope measurements during system validation.

Why must unused inputs on ISL24010IVZ-T be tied to ground?

Unused inputs on ISL24010IVZ-T left floating cause rail-to-rail oscillation on corresponding outputs due to internal high-impedance states and lack of input hysteresis. This results in excessive power dissipation, localized heating, and potential thermal shutdown or permanent damage. Grounding all unused IN1–IN8 pins ensures stable quiescent operation and maintains specified 250ns propagation delay and 150ns rise time performance across active channels.

Can ISL24010IVZ-T drive a 3300pF load within its specified timing limits?

Yes - the ISL24010IVZ-T is explicitly characterized to drive up to 3300pF in ≤500ns, as confirmed in Figure 7–12 of the FN6124 datasheet. At VON1/VON2 = 22V and VOFF = -5V, rise time remains ≤1600ns and fall time ≤2000ns into 3300pF, satisfying typical TFT-LCD panel timing budgets when combined with appropriate series termination and layout-controlled trace capacitance.

What is the functional difference between VON1 and VON2 on ISL24010IVZ-T?

VON1 supplies outputs 1–6; VON2 supplies outputs 7–8. This separation enables flicker-reduction slicing: VON1 can be modulated dynamically while VON2 remains constant, allowing outputs 1–6 to generate staggered gate pulses that reduce visual artifacts. VON2 must always be ≥ VON1 to prevent forward-biasing the internal ESD diode between them - a hard design constraint enforced by the pin-level circuit architecture.

Is ISL24010IVZ-T pin-compatible with ISL24011IVZ-T?

Yes - ISL24010IVZ-T and ISL24011IVZ-T share identical TSSOP-20 pinout, footprint, and terminal functions. The ISL24011IVZ-T adds an internal charge pump to generate VON2 from VON1, repurposing pin 11 (VON2) as a charge-pump output rather than an external supply input. When substituting, verify that the charge-pump output meets required VON2 voltage stability and ripple specs for the target panel.
