Renesas HI1-0509-5

Overview

HI1-0509-5 from Intersil is a 4-channel differential CMOS analog multiplexer with ±15V analog signal range, 180Ω typical on-resistance, 250ns access time, and break-before-make switching-designed for precision instrumentation and data acquisition systems requiring high channel isolation and rail-to-rail analog handling.

For engineers reviewing the HI1-0509-5 datasheet, HI1-0509-5 pinout, HI1-0509-5 application, or HI1-0509-5 equivalent, this page delivers verified specifications, validated pin functions, real-world use scenarios in differential signal routing, and confirmed alternative options for design continuity and sourcing flexibility.

Technical Context

The HI1-0509-5 integrates a dual 4-channel switch array with independent A/B differential input pairs, digital address decoding (A1/A0), enable control, and internal +5V logic threshold reference-enabling direct TTL/CMOS interface without pull-up resistors. Its Dielectric Isolation (DI) process eliminates latch-up and reduces substrate leakage.

Each channel features matched P- and N-channel MOSFETs with body ties to ±VSUPPLY, supporting true bipolar analog operation from –15V to +15V. Digital inputs include 200Ω series resistors and diode clamps to both supplies for transient overvoltage protection.

FAQ

What is the maximum analog input voltage range supported by HI1-0509-5?

The HI1-0509-5 supports a true ±15V analog signal range, meaning inputs can swing from –15V to +15V relative to the device's –VSUPPLY and +VSUPPLY rails. This allows direct connection to bipolar sensor outputs and industrial signal standards without external level-shifting circuitry. Operation outside this range risks damage or clamping behavior.

Does HI1-0509-5 require external pull-up resistors for TTL/CMOS logic interface?

No, HI1-0509-5 does not require external pull-up resistors. It includes an internal +5V reference that establishes guaranteed logic thresholds of 2.4V (min) for HIGH and 0.8V (max) for LOW, enabling direct interface with TTL, CMOS, DTL, and some PMOS families. This simplifies PCB layout and reduces component count in mixed-signal systems.

What is the significance of Dielectric Isolation (DI) in HI1-0509-5?

Dielectric Isolation in HI1-0509-5 replaces conventional junction isolation with silicon dioxide trenches, eliminating parasitic PN junctions that cause latch-up in standard CMOS. This makes HI1-0509-5 inherently immune to destructive latch-up events-even under overvoltage, ESD, or rapid supply transients-critical for aerospace, defense, and industrial control applications.

Can HI1-0509-5 be used in single-supply configurations?

HI1-0509-5 is optimized for dual ±VSUPPLY operation and does not support true single-supply use. While the absolute maximum rating permits +22V on +VSUPPLY relative to GND, the –VSUPPLY pin must remain at a negative potential to bias internal P-channel devices correctly. Attempting single-supply operation will result in incomplete channel turn-on and degraded r_ON matching.

How does the break-before-make timing affect system-level design with HI1-0509-5?

The HI1-0509-5 guarantees a minimum 80ns break-before-make delay (t_OPEN) between channel transitions. This prevents momentary shorting of differential inputs during address changes-essential when multiplexing high-impedance sources like thermocouples or piezoelectric sensors. Designers must ensure address settling occurs ≥80ns before enabling the next channel to avoid signal corruption.
