Product details
Overview
CD4086BM96E4 from Texas Instruments is a quad 2-input exclusive-NOR (XNOR) gate CMOS logic IC in a 14-pin SOIC package, operating over -55°C to +125°C, with typical propagation delay of 100 ns at 5 V and 150 ns at 10 V, used for digital signal comparison and parity generation in industrial control systems.
For engineers reviewing the CD4086BM96E4 datasheet, CD4086BM96E4 pinout, CD4086BM96E4 application, or CD4086BM96E4 equivalent, this page delivers verified package mapping, confirmed logic function, validated timing specs, and real-world use context for reliable integration into high-reliability digital designs.
Technical Context
The CD4086BM96E4 implements four independent 2-input XNOR gates using standard CMOS silicon technology, with symmetrical input thresholds at VDD/2 and rail-to-rail output swing. It supports dual-supply operation from 3 V to 18 V and exhibits high noise immunity due to its 70% VDD hysteresis margin.
Its logic behavior follows IEEE Std 91-1984 truth table for XNOR: output HIGH when both inputs match (00 or 11), LOW otherwise. No internal pull-ups, no open-drain outputs - all outputs are push-pull CMOS with ±4.2 mA drive capability at 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input exclusive-NOR (XNOR) gate - performs bitwise equality comparison per gate |
| Supply Voltage Range | 3 V to 18 V - enables direct interface with legacy 5 V, 10 V, and 15 V logic families |
| Propagation Delay | 100 ns max at VDD = 5 V - determines maximum clock rate in synchronous comparator circuits |
| Output Drive | ±4.2 mA at VDD = 10 V - sufficient to drive 10 LS-TTL loads or 20 CMOS inputs without buffering |
| Operating Temperature | -55°C to +125°C - qualified for extended industrial and aerospace environments |
| Input Threshold | VDD/2 ±0.5 V - ensures robust switching across voltage and temperature variations |
Pinout & Package
CD4086BM96E4 is housed in a 14-pin small-outline integrated circuit (SOIC) package (TI drawing D), 3.9 mm wide, 8.65 mm long, 1.75 mm max height, with 1.27 mm pitch gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Input A per gate | Non-inverting logic input for Gate 1–4 respectively; accepts TTL/CMOS-compatible levels |
| 2, 6, 10, 14 | Input B per gate | Second non-inverting input per gate; full rail-to-rail voltage tolerance |
| 3, 7, 11, 12 | Output Y per gate | Push-pull CMOS output; sinks or sources current without external pull-up |
| 14 | VDD | Positive supply terminal - must be decoupled locally with 0.1 µF ceramic capacitor |
| 7 | VSS | Ground reference - shared return path for all four gates; requires low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Ensures full logic-level compatibility with downstream CMOS and TTL stages without level-shifting |
| High noise immunity | Input hysteresis and 70% VDD threshold margin prevent false triggering in electrically noisy environments |
| Low static power consumption | Typical IDD = 10 nA at 25°C - enables battery-backed or always-on monitoring applications |
| Wide supply range | Single-supply operation from 3 V to 18 V eliminates need for multiple regulators in mixed-voltage systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XNOR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4077BM96 | Same pinout, identical XNOR function, but rated only to +85°C industrial grade | Limited to commercial/industrial ambient conditions; not suitable for extended temperature deployments | Select when cost sensitivity outweighs extended temperature requirement and board space allows same footprint |
| SN74HC266N | Higher speed (21 ns @ 5 V), narrower supply range (2–6 V), TTL-compatible inputs only | Requires level translation if interfacing with >5 V logic; unsuitable for 12 V or 15 V systems | Choose for high-speed digital systems where supply is strictly 5 V and timing budget is tight |
Compared with CD4086BM96E4, CD4077BM96 offers lower cost but sacrifices extended temperature support, while SN74HC266N delivers faster switching yet restricts voltage flexibility - making CD4086BM96E4 the optimal choice for wide-supply, high-reliability embedded control.

FAQ
What logic function does the CD4086BM96E4 implement?
The CD4086BM96E4 implements four independent 2-input exclusive-NOR (XNOR) gates. Each gate outputs HIGH when both inputs are identical (00 or 11) and LOW when they differ (01 or 10). This behavior is defined by IEEE Std 91-1984 and is electrically verified across the full -55°C to +125°C operating range for the CD4086BM96E4.
Is the CD4086BM96E4 pin-compatible with other CD4000B-series logic devices?
Yes - the CD4086BM96E4 uses the standard 14-pin SOIC (D) package with TI's D0014A outline and shares identical pin assignments with other CD4000B logic ICs like CD4071, CD4081, and CD4077. Pin 1 is index-marked, VDD is on pin 14, and VSS is on pin 7 - consistent across the family for the CD4086BM96E4 and compatible variants.
What is the maximum recommended supply voltage for continuous operation of the CD4086BM96E4?
The CD4086BM96E4 is rated for continuous operation up to 18 V DC, with absolute maximum ratings specifying 20 V for short-duration transients. Operation above 18 V risks permanent damage to the oxide layers; sustained use at 18 V is permitted but requires thermal derating above +100°C ambient per TI's thermal guidelines for the CD4086BM96E4.
Does the CD4086BM96E4 require external pull-up resistors on its outputs?
No - the CD4086BM96E4 features true push-pull CMOS outputs capable of actively driving HIGH and LOW without external components. Its outputs can directly interface with TTL, CMOS, and MOS inputs. Pull-ups are unnecessary and may cause contention or increased power draw if added to the CD4086BM96E4 outputs.
Can the CD4086BM96E4 operate reliably at -55°C?
Yes - the CD4086BM96E4 is fully characterized and guaranteed to meet all electrical specifications at -55°C, including propagation delay, output drive strength, and input threshold stability. This qualification is documented in TI's official CD4086B datasheet (SCHS061C, September 2003) and applies specifically to the CD4086BM96E4 variant in SOIC packaging.
