Product details
Overview
HI1-0508-5 from Intersil is a single 8-channel CMOS analog multiplexer with dielectric isolation, ±15V analog signal range, 180Ω typical on-resistance, 250ns access time, and break-before-make switching-used in precision instrumentation data acquisition systems for channel selection under wide temperature and supply conditions.
For engineers reviewing the HI1-0508-5 datasheet, HI1-0508-5 pinout, HI1-0508-5 application, or HI1-0508-5 equivalent, this page delivers verified electrical specs, truth table behavior, thermal performance across -55°C to +125°C, and direct substitution guidance for legacy DG508A/DG508AA designs.
Technical Context
The HI1-0508-5 integrates an on-chip +5V reference for TTL/CMOS-compatible logic thresholds (2.4V min high, 0.8V max low), digital protection circuitry including 200Ω series resistors and diode clamps on all address/enable inputs, and a decoder/driver that selects one of eight analog inputs to a common output based on A0–A2 address lines.
Its dielectric isolation (DI) process eliminates latch-up, reduces substrate leakage, and lowers parasitic capacitance versus junction-isolated CMOS-enabling reliable operation in high-precision, high-voltage analog signal routing where channel crosstalk and power supply noise must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG508A | Same 8-channel architecture, but junction-isolated CMOS; higher on-resistance (200Ω typ), no internal +5V reference | Lacks DI-based latch-up immunity and requires external logic-level translation for TTL interfacing | Select DG508A only if legacy footprint compatibility is mandatory and latch-up risk is mitigated externally |
| ADG508F | Enhanced latch-up immunity (not DI), 120Ω on-resistance, wider –40°C to +85°C temp range, but no internal reference | Requires external 2.4V threshold generation; superior leakage (0.01nA) but lower supply voltage tolerance (±16.5V max) | Choose ADG508F for improved leakage and extended commercial temp range where DI is not required |
Compared with DG508A and ADG508F, the HI1-0508-5 uniquely combines dielectric isolation, integrated +5V logic reference, and guaranteed ±15V analog range-making it optimal for high-reliability, wide-temperature industrial instrumentation where latch-up prevention and simplified logic interfacing are critical.

FAQ
What is the operating temperature range for HI1-0508-5?
The HI1-0508-5 is rated for 0°C to +75°C operation, as indicated by the "-5" suffix in its part number. This range is validated per the Absolute Maximum Ratings table and supported by characterization data across dynamic parameters like on-resistance and leakage current.
Does HI1-0508-5 require external pull-up resistors for TTL logic interface?
No, HI1-0508-5 does not require external pull-up resistors because it includes an internal +5V reference that establishes guaranteed logic thresholds of 2.4V (min high) and 0.8V (max low), enabling direct connection to TTL, CMOS, DTL, and some PMOS outputs.
What is the maximum analog input voltage allowed on HI1-0508-5?
The HI1-0508-5 supports analog input voltages from –15V to +15V when operated with ±15V supplies. Absolute maximum ratings permit up to (V+) +2V and (V–) –2V, but sustained operation beyond ±15V requires verification of clamping diode current limits per the datasheet.
How does the break-before-make feature function in HI1-0508-5?
The HI1-0508-5 implements break-before-make switching with an 80ns typical delay between channel turn-off and next channel turn-on, preventing momentary shorting between analog inputs during address transitions-verified via truth table and dynamic test waveforms in the datasheet.
Is HI1-0508-5 pin-compatible with DG508A?
Yes, HI1-0508-5 is pin-compatible with DG508A in the 16-lead PDIP package (E16.3), sharing identical pinout, supply connections, address inputs, enable, and I/O assignments-enabling drop-in replacement where dielectric isolation and internal reference benefits are needed.
