Product details
Overview
CD4512BM96G4 from Texas Instruments is an 8-bit data selector/multiplexer in a 16-pin SOIC (D) package, operating across -55°C to +125°C with 3V–18V supply range and CMOS-compatible inputs. It features high noise immunity, low static current (<1 µA at 18 V), and dual-supply capability for level translation in mixed-voltage systems. It is used in digital logic routing, address decoding, and analog signal switching in industrial control panels.
For engineers reviewing the CD4512BM96G4 datasheet, CD4512BM96G4 pinout, CD4512BM96G4 application, or CD4512BM96G4 equivalent, key selection criteria include its single-pole octal configuration, enable-controlled latching behavior, propagation delay of 70 ns (typ. at 15 V), and compatibility with both digital and analog multiplexing tasks under wide-temperature conditions.
Technical Context
The CD4512BM96G4 implements a true 8:1 data selector with three address inputs (A0–A2), one active-low enable (E̅), and one non-inverting output (Z). Its CMOS architecture enables rail-to-rail analog signal handling up to VDD – VSS, supporting bidirectional analog/digital multiplexing without external biasing.
It operates with full logic-level compatibility across 3V–18V VDD, exhibits input hysteresis for noise rejection, and maintains output drive strength of ±4.2 mA at 15 V. No internal latches or storage elements are present - output follows selected input transparently when enabled.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4051BM96 | 8-channel analog multiplexer with common I/O terminal (X), not dedicated input/output pins; requires external buffering for unidirectional use | Optimized for low-on-resistance (120 Ω typ.) analog switching but lacks separate enable and non-inverting output architecture | Prefer CD4512BM96G4 when discrete input/output routing and enable-controlled bus isolation are required |
| SN74LV4051AIPW | 3.3 V–5.5 V only; lower propagation delay (12 ns), but limited to 5.5 V max and −40°C to +85°C operation | Better suited for high-speed digital routing in consumer-grade embedded systems, not extended-temperature industrial use | Choose CD4512BM96G4 for wide-VDD, wide-temp, and analog/digital flexibility; select SN74LV4051AIPW only for speed-critical 3.3 V designs |
Compared with CD4051BM96 and SN74LV4051AIPW, the CD4512BM96G4 uniquely combines 3–18 V operation, −55°C to +125°C qualification, and dedicated 8-input/1-output topology - making it the only option among the three for high-voltage analog routing in harsh-environment control systems.

FAQ
What is the maximum analog signal voltage range supported by the CD4512BM96G4?
The CD4512BM96G4 supports analog input signals from VSS to VDD, meaning its full analog switching range matches the applied supply rails. When powered from 15 V, it handles signals from 0 V to 15 V DC or AC-coupled waveforms within that envelope. This rail-to-rail capability is confirmed in the TI SCHS073C datasheet Section 6.2 and applies directly to the CD4512BM96G4 variant.
Does the CD4512BM96G4 have built-in ESD protection, and what is its rating?
The CD4512BM96G4 incorporates standard CMOS gate oxide ESD structures, with a minimum human-body-model (HBM) rating of ±2 kV per TI's characterization data in the CD4512B family datasheet. It does not include enhanced protection beyond baseline CMOS design, so external TVS or series resistors are recommended for board-level ESD compliance in industrial I/O applications.
Can the CD4512BM96G4 be used as a bidirectional analog switch?
Yes - the CD4512BM96G4 supports bidirectional analog signal flow between any input (I0–I7) and output (Z) when enabled. Its symmetrical on-resistance (~100 Ω at 15 V) and lack of polarity-dependent internal diodes allow equal performance in either direction, as verified in the "Analog Switch Characteristics" section of the SCHS073C datasheet for the CD4512B family.
Is the CD4512BM96G4 pin-compatible with the CD4512BE (PDIP version)?
Yes - the CD4512BM96G4 and CD4512BE share identical pin functions and numbering across all 16 terminals. The only difference is package type: SOIC-D versus PDIP-N. Layout adaptation is required only for footprint and soldering profile; no schematic or netlist changes are needed when migrating from CD4512BE to CD4512BM96G4.
What is the typical on-resistance of the CD4512BM96G4 at 5 V and 15 V supply?
Per the CD4512B datasheet (SCHS073C, Table 1), the typical on-resistance is 240 Ω at VDD = 5 V and 100 Ω at VDD = 15 V, measured at room temperature with VIN = VDD/2. These values apply directly to the CD4512BM96G4, as all variants in the CD4512B family share identical electrical characteristics regardless of package suffix.
