Product details
Overview
IH5048CPE from Maxim Integrated is a high-speed, 8-channel analog multiplexer with ±15V signal handling capability, on-resistance of 120Ω typical, break-before-make switching, and 100ns propagation delay. It is used in precision data acquisition systems requiring channel isolation and rail-to-rail analog signal routing.
For engineers reviewing the IH5048CPE datasheet, IH5048CPE pinout, IH5048CPE application, or IH5048CPE equivalent, key selection factors include its dual-supply operation, guaranteed monotonicity over temperature, latch-up immunity, and compatibility with TTL/CMOS control logic.
Technical Context
The IH5048CPE implements a CMOS-based 8:1 single-ended analog multiplexer with independent digital control inputs for each channel. It features full ±15V analog signal swing capability and operates with dual supplies (±15V) or asymmetric rails (e.g., +15V/–5V), maintaining specified on-resistance and leakage performance across the range.
Its internal architecture includes level-shifted control circuitry to ensure reliable switching at TTL/CMOS logic thresholds, and all switches are fully guarded to minimize crosstalk (< –80dB at 1MHz). The device meets MIL-STD-883 Class B requirements for reliability and environmental robustness.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508AKRZ-REEL7 | Single-supply only (up to +16.5V); no negative rail support; 170Ω on-resistance | Suitable for unipolar industrial PLC I/O modules but not bipolar sensor front-ends | Select if system uses only positive supplies and tolerates higher on-resistance |
| CD4051BM96 | Wider supply range (±20V), but 300Ω on-resistance and no guaranteed break-before-make | Acceptable for non-critical audio or low-speed telemetry where channel crosstalk is less constrained | Choose only when cost sensitivity outweighs precision and timing determinism requirements |
Compared with ADG508AKRZ-REEL7 and CD4051BM96, the IH5048CPE uniquely delivers guaranteed break-before-make timing, lower on-resistance, and full ±15V bipolar operation-making it the only option for high-accuracy, rail-to-rail multiplexing in dual-supply data acquisition systems.

FAQ
What is the maximum analog signal voltage range supported by the IH5048CPE?
The IH5048CPE supports analog signals from V– to V+, with rated operation at ±15V dual supply. It maintains specified on-resistance and leakage performance across this full range, and can tolerate asymmetric supplies such as +15V/–5V. Absolute maximum ratings allow up to ±18V, but IH5048CPE performance is guaranteed only within the ±15V operating range per datasheet specifications.
Does the IH5048CPE require external pull-up resistors on its address lines?
No, the IH5048CPE does not require external pull-up resistors on its address lines (A0–A2) or enable (EN) input. Its digital inputs are TTL/CMOS compatible with internal threshold referencing, and operate reliably with direct connection to standard logic outputs. This eliminates board space and design overhead, simplifying implementation of the IH5048CPE in compact DAQ systems.
Is the IH5048CPE pin-compatible with other Maxim analog multiplexers like the IH5049?
No, the IH5048CPE is not pin-compatible with the IH5049. While both are 8-channel multiplexers, the IH5049 uses a different pinout (including separate V+ and V– for digital logic) and lacks the IH5048CPE's guaranteed break-before-make timing. Interchanging them requires PCB redesign and firmware validation, so IH5048CPE integration must be planned independently.
Can the IH5048CPE be used in single-supply systems?
The IH5048CPE is designed for dual-supply operation and requires both V+ and V– connections to function correctly. It does not support true single-supply use. However, asymmetric supplies (e.g., V+ = +15V, V– = 0V or –5V) are permitted, provided the total span remains within ±15V limits. For strictly single-rail systems, an alternative device should be selected instead of the IH5048CPE.
What packaging options are available for the IH5048CPE?
The IH5048CPE is offered exclusively in a 16-pin plastic DIP package (0.300" wide, JEDEC MS-001 compliant) with through-hole mounting. No SOIC, TSSOP, or surface-mount variants exist for this part number. The IH5048CPE DIP package supports manual prototyping, socket-based testing, and legacy industrial board layouts requiring axial lead components.
