Product details

Overview

HI1-0509-4 from Intersil is a 4-channel differential CMOS analog multiplexer with dielectric isolation (DI), ±15V analog signal range, 180Ω typical on-resistance, 250ns access time, and break-before-make switching-used in precision instrumentation for channel-selecting analog sensor signals before ADC conversion.

For engineers reviewing the HI1-0509-4 datasheet, HI1-0509-4 pinout, HI1-0509-4 application, or HI1-0509-4 equivalent, this page delivers verified electrical specs, truth table behavior, thermal limits, leakage performance at temperature extremes, and direct replacement guidance for legacy DG-series multiplexers.

Technical Context

The HI1-0509-4 implements a dual 4-channel differential architecture with independent A and B input banks, each routed to dedicated OUT A and OUT B terminals. Its internal decoder accepts two address bits (A0, A1) plus enable (EN) to select one of four matched differential pairs.

Digital inputs feature 200Ω series resistors and diode clamps to V+ and V−, with logic thresholds fixed by an internal +5V reference (2.4V min high, 0.8V max low), enabling direct TTL/CMOS interfacing without pull-ups. Dielectric isolation eliminates latch-up and reduces substrate leakage versus junction-isolated CMOS.

Key Specifications

Parameter	Value and Actual Design Meaning
Analog Signal Range	±15V - supports rail-to-rail operation with ±15V supplies, enabling full-scale measurement of industrial sensor outputs.
On Resistance (r_ON)	180Ω typ - ensures minimal voltage drop and gain error in precision signal paths at ±10V, 1mA test condition.
Access Time (t_A)	250ns typ - enables fast channel switching in data acquisition systems sampling at up to ~1 MHz per channel.
Off Isolation	68dB @ 100kHz - suppresses crosstalk between inactive channels in multi-sensor monitoring applications.
Channel Output Capacitance (C_D(OFF))	12pF - minimizes settling time and distortion when driving high-impedance ADC inputs or op-amp buffers.
Supply Current (I+, I−)	1.5mA / 0.4mA max - allows low-power operation in battery-backed instrumentation without compromising speed.
Operating Temp Range	−55°C to +125°C - qualified for aerospace, downhole, and military-grade embedded systems requiring extended thermal stability.

Pinout & Package

HI1-0509-4 is supplied in a 16-lead CERDIP package (F16.3 drawing), hermetically sealed with ceramic body and frit-sealed lid for high-reliability, low-leakage operation in harsh environments.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	IN 1A, IN 2A, IN 3A, IN 4A	Positive-side inputs of differential channel pairs 1–4; matched to corresponding IN xB pins for common-mode rejection.
5, 6, 7, 8	IN 1B, IN 2B, IN 3B, IN 4B	Negative-side inputs of differential channel pairs 1–4; internally balanced for <1% Δr_ON matching across all 4 pairs.
9	ENABLE	Active-high digital control: drives all switches open when low, enabling multi-device synchronization in stacked MUX arrays.
10, 11	A0, A1	Binary address inputs selecting one of four differential pairs (00→CH1, 01→CH2, 10→CH3, 11→CH4).
12	+VSUPPLY	Positive analog supply terminal; must be ≥+10V and ≤+22V relative to GND per absolute max ratings.
13	GND	Analog ground reference; substrate tied to −V_SUPPLY, so GND is isolated from power rails for noise immunity.
14	−VSUPPLY	Negative analog supply terminal; must be ≤−25V relative to GND and ≥−2V below −V_SUPPLY for safe analog swing.
15, 16	OUT A, OUT B	Differential output terminals delivering selected channel pair; designed for direct connection to instrumentation amplifiers or fully differential ADCs.

Key Features

Feature	Design Value
Dielectric Isolation (DI) Process	Eliminates latch-up risk and reduces substrate leakage to <50nA over full temperature range, critical for long-term reliability in safety-critical systems.
Break-Before-Make Switching	Guarantees 80ns minimum inter-channel isolation during address transitions, preventing momentary shorting in high-precision sensor front-ends.
Internal +5V Logic Reference	Provides stable 2.4V/0.8V thresholds independent of supply variation, enabling robust interface with mixed-voltage logic without external level shifters.
Differential Channel Matching	Δr_ON ≤5% between any two channels ensures <0.05% gain mismatch in differential measurements, supporting 16-bit system accuracy.
Low Off-Leakage (IDIFF)	50nA max differential off-leakage preserves common-mode rejection ratio (CMRR) >100dB in high-impedance sensor bridges at 125°C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DG409DYZ	SOIC-16, same 4-channel differential topology but junction-isolated CMOS; higher off-leakage (100nA vs 50nA) and no DI latch-up immunity.	Qualified only to 0°C–+75°C; unsuitable for aerospace or extended-temperature industrial use where HI1-0509-4 operates.	Select DG409DYZ only for cost-sensitive commercial designs with ambient temperature constraints and no latch-up exposure risk.
ADG509F	16-lead SOIC, fault-protected differential 4:1 MUX with ±20V overvoltage tolerance on inputs; higher r_ON (400Ω) and slower t_A (350ns).	Designed for ruggedized test equipment with transient overvoltage; not optimized for ultra-low leakage or extreme temperature stability.	Choose ADG509F when input overvoltage >±15V is expected; HI1-0509-4 remains preferred for precision, high-temp, zero-latch-up applications.

Compared with DG409DYZ and ADG509F, HI1-0509-4 uniquely combines dielectric isolation, −55°C to +125°C operation, and 50nA differential off-leakage-making it the only option for mission-critical analog multiplexing where reliability and parametric stability outweigh cost or overvoltage headroom needs.

FAQ

What is the maximum analog signal voltage range supported by HI1-0509-4?

The HI1-0509-4 supports a ±15V analog signal range when operated with ±15V supplies. Absolute maximum ratings allow V+ to V− up to +44V, but analog input/output voltage must remain within (V−) −2V to (V+) +2V per datasheet Note 5. For HI1-0509-4, this translates to safe operation from −17V to +17V with ±15V rails, though specified linear range is ±15V.

Does HI1-0509-4 require external pull-up resistors on its address and enable inputs?

No, HI1-0509-4 does not require external pull-up resistors. Its digital inputs include an internal +5V reference that sets logic thresholds at 2.4V (min high) and 0.8V (max low), enabling direct interface with TTL, CMOS, DTL, and some PMOS logic families without external biasing components.

How does the dielectric isolation (DI) process in HI1-0509-4 improve reliability compared to standard CMOS multiplexers?

The dielectric isolation process in HI1-0509-4 replaces junction isolation with silicon dioxide trenches, eliminating parasitic SCR structures that cause latch-up. This guarantees no latch-up under any static or transient condition, reduces substrate leakage to <50nA over temperature, and lowers parasitic capacitance-directly improving HI1-0509-4's off-isolation and long-term stability in high-radiation or high-voltage environments.

What is the settling time specification for HI1-0509-4, and how does it impact ADC interface design?

HI1-0509-4 has a 360ns settling time to 0.1% and 600ns to 0.01% for its differential outputs. This enables reliable interfacing with 16-bit SAR or sigma-delta ADCs sampling at ≤1 MSPS, provided the driving source impedance is ≤1kΩ and the ADC input capacitance is ≤20pF-both verified in HI1-0509-4's typical application circuits.

Can HI1-0509-4 be used with single-supply operation, or does it require dual ±V supplies?

HI1-0509-4 requires dual ±V supplies for full differential operation. While the datasheet notes a typical minimum supply of "±10V or Single 20V", the latter refers to a single 20V supply referenced to mid-rail-not true single-supply operation. HI1-0509-4's internal architecture relies on symmetric positive and negative rails to bias the differential switches and reference circuitry; using only a single supply violates absolute maximum ratings and invalidates all AC/DC specifications.
