Product details
Overview
HI4P0509-5Z 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. It operates from 0°C to +75°C in a 20-lead PLCC package and is used in precision instrumentation for channel-selecting analog sensor signals prior to ADC conversion.
For engineers reviewing the HI4P0509-5Z datasheet, HI4P0509-5Z pinout, HI4P0509-5Z application, or HI4P0509-5Z equivalent, key selection criteria include differential pair routing support, low off-capacitance (12pF), guaranteed TTL/CMOS compatibility without pull-ups, and dielectric isolation to prevent latch-up in high-reliability systems.
Technical Context
The HI4P0509-5Z integrates an internal +5V reference for logic threshold stabilization, enabling direct interface with TTL, CMOS, DTL, and some PMOS families. Its digital inputs include 200Ω series resistors and diode clamps to both supplies for transient overvoltage protection.
Constructed using Dielectric Isolation (DI) CMOS process, the device eliminates latch-up risk and achieves lower substrate leakage and parasitic capacitance than junction-isolated alternatives. The decoder drives four differential switch pairs with address inputs A0/A1 and an enable input for multi-device configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG409DYZ | Pin-compatible replacement specified in datasheet; identical 4-channel differential topology, same PLCC-20 package, ±15V range, but higher 200Ω on-resistance (typ) | Same functional role in differential sensor routing; requires verification of 200Ω vs. 180Ω impact on gain error in ultra-precision designs | Select DG409DYZ only if HI4P0509-5Z is unavailable; confirm layout compatibility and validate settling performance at target sample rate |
| ADG509AKRZ | 4-channel differential mux in 16-lead SOIC; ±15V range, 120Ω on-resistance, but lacks internal +5V reference - requires external logic-level translation for TTL inputs | Used where board space is constrained and lower on-resistance is prioritized over logic interface simplicity | Choose ADG509AKRZ when minimizing on-resistance is critical and external level-shifting circuitry is acceptable |

FAQ
What is the maximum analog input voltage range supported by the HI4P0509-5Z?
The HI4P0509-5Z supports a ±15V analog signal range, meaning it can pass signals from –15V to +15V relative to its analog ground. This range is valid when powered with ±15V supplies and remains within absolute maximum ratings of V+ to V– ≤ +44V and analog inputs clamped between (V–) –2V and (V+) +2V per datasheet specifications.
Does the HI4P0509-5Z require external pull-up resistors for TTL-level digital inputs?
No, the HI4P0509-5Z does not require external pull-up resistors. Its internal +5V reference establishes guaranteed logic thresholds of 2.4V minimum for HIGH and 0.8V maximum for LOW, enabling direct interface with TTL, CMOS, DTL, and some PMOS logic families without additional biasing components.
What is the purpose of the NC pins on the HI4P0509-5Z PLCC package?
The NC (no-connect) pins on the HI4P0509-5Z - pins 17 through 20 - correspond to unused die pads and must remain unconnected in the PCB layout. Connecting them may cause unpredictable behavior or violate internal isolation boundaries, as confirmed in the FN3142 datasheet pinout diagrams and package notes.
How does the Dielectric Isolation (DI) process benefit the HI4P0509-5Z in industrial applications?
The DI process in the HI4P0509-5Z eliminates latch-up susceptibility, reduces substrate leakage current by orders of magnitude, and lowers parasitic capacitance compared to junction-isolated CMOS. This ensures reliable operation in noisy industrial environments with high-voltage transients, such as motor drive feedback loops or PLC I/O modules.
Is the HI4P0509-5Z RoHS compliant and compatible with Pb-free reflow processes?
Yes, the HI4P0509-5Z is RoHS compliant and uses 100% matte tin plate with anneal finish (e3 termination). It meets or exceeds IPC/JEDEC J-STD-020 Pb-free reflow requirements and is rated for MSL classification appropriate for standard Pb-free assembly processes, as documented in the FN3142 ordering information section.
