ISL55100BIRZ-T7A

Specialty Logic Overview

The ISL55100BIRZ-T7A is a quad pin driver and window comparator fabricated in a wide voltage CMOS process. It integrates four channels of programmable drivers and window comparators into a compact 72-lead QFN package. The device supports an input supply range of 9V to 18V, with a maximum operating voltage of 18V. Each channel features independent driver levels and data control. The receiver inputs utilize dual comparators providing high and low threshold levels for window detection. Digital inputs support differential or single-ended logic families, while comparator outputs are user-defined to interface with various digital technologies.

• Integrates four independent channels combining programmable drivers and window comparators within a single integrated circuit
• Supports direct interfacing with LVDS or CML outputs via differential mode digital inputs
• Features dual-level input thresholds per channel for precise window comparison functionality
• Provides user-defined comparator output levels to mate directly with diverse digital technology standards

Specialty Logic Applications

• Test During Burn-In (TDBI) applications requiring high functional density
• Driving high voltage super voltage level circuits for special test modes
• Interface solutions for Flash devices requiring cost-effective pin electronics
• Connecting digital logic families such as TTL, ECL, and CMOS to custom level circuitry

Specialty Logic Procurement Notes

Verify component status carefully as this part may be discontinued or subject to limited supply constraints. Confirm the specific suffix T7A corresponds to the required tape and reel packaging configuration. Ensure compatibility with the 72-VFQFN bare pad footprint during PCB layout. Check for any recent product change notices regarding labeling or manufacturing site updates before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when designing systems that require simultaneous signal driving and window comparison functions on multiple lines. It is suitable for environments demanding low channel-to-channel timing skew and small physical footprint. Consider the 18V I/O range capability if interfacing with higher voltage legacy logic families. Evaluate power consumption requirements against the specified operating current limits for thermal management.
