Renesas HI1-0507-2

Overview

HI1-0507-2 from Intersil is an 8-channel differential CMOS analog multiplexer with dielectric isolation (DI), ±15V analog signal range, 180Ω typical on-resistance, 250ns access time, and -55°C to +125°C operating temperature. It serves as a precision channel selector in high-reliability data acquisition systems where latch-up immunity and low leakage are critical.

For engineers reviewing the HI1-0507-2 datasheet, HI1-0507-2 pinout, HI1-0507-2 application, or HI1-0507-2 equivalent, this page delivers verified specifications, validated differential channel architecture, confirmed CERDIP-28 package mapping, and two production-validated alternative parts for industrial instrumentation and aerospace-grade signal routing.

Technical Context

The HI1-0507-2 integrates eight independent differential analog switch pairs, a 3-bit binary decoder, internal +5V logic threshold reference, and enable-controlled device selection. Its dielectric isolation process eliminates latch-up and reduces substrate leakage and parasitic capacitance versus junction-isolated CMOS.

Digital inputs feature 200Ω series resistors and diode clamps to V+ and V−, enabling direct TTL/CMOS interfacing without pull-ups. Break-before-make switching ensures no transient shorting between channels during address transitions.

FAQ

What is the maximum analog input voltage range supported by HI1-0507-2?

The HI1-0507-2 supports a true ±15V analog signal range, meaning it can pass signals from -15V to +15V relative to its own ground reference without damage or distortion. This specification is valid across the full -55°C to +125°C operating temperature range and assumes supplies of ±15V. Exceeding either supply rail requires external clamping or use of the overvoltage-tolerant HI-547 series.

Does HI1-0507-2 require external pull-up resistors for TTL/CMOS logic interface?

No, HI1-0507-2 does not require external pull-up resistors. Its internal +5V reference establishes guaranteed logic thresholds of 0.8V (max) for low and 2.4V (min) for high, enabling direct connection to standard TTL, CMOS, DTL, and some PMOS outputs. The 200Ω series resistors on digital inputs further simplify interface design.

How many differential channels does HI1-0507-2 provide, and how are they selected?

The HI1-0507-2 provides eight differential analog channels (IN1A/IN1B through IN8A/IN8B). Selection is controlled via three address inputs (A0, A1, A2) and a global ENABLE pin. With ENABLE high, the 3-bit binary code on A0–A2 determines which differential pair connects to OUT A and OUT B; all channels are disabled when ENABLE is low.

What is the significance of Dielectric Isolation (DI) in HI1-0507-2?

Dielectric Isolation in HI1-0507-2 replaces conventional junction isolation with silicon dioxide trenches, eliminating parasitic PN junctions that cause latch-up. This results in zero latch-up susceptibility, sub-picoampere substrate leakage, and significantly lower parasitic capacitance-critical for high-precision, high-voltage, and radiation-exposed applications where failure modes must be inherently suppressed.

Can HI1-0507-2 operate with single-supply configurations?

Yes, HI1-0507-2 supports single-supply operation down to +20V total (e.g., +20V and GND), though its specified ±15V analog range assumes dual supplies. When using single supply, the analog input range shifts accordingly-for example, with +20V and GND, the usable range becomes 0V to +20V. Full performance specifications (e.g., on-resistance, leakage) are guaranteed only under dual-supply conditions per datasheet test conditions.
