Texas Instruments CD4086BM96G4

Overview

CD4086BM96G4 from Texas Instruments is a quad 2-input exclusive-NOR (XNOR) gate CMOS logic IC in a 14-pin SOIC package, operating across -55°C to +125°C, with typical propagation delay of 100 ns at 5 V and supply voltage range of 3 V to 18 V. It serves as a level-shifting, noise-immune combinational logic element in industrial control sequencers and battery-powered instrumentation interfaces.

For engineers reviewing the CD4086BM96G4 datasheet, CD4086BM96G4 pinout, CD4086BM96G4 application, or CD4086BM96G4 equivalent, key selection considerations include its dual-rail CMOS compatibility, wide temperature range, low static current (<1 µA), and direct replacement capability for legacy CD4000-series XNOR functions without layout change.

Technical Context

The CD4086BM96G4 implements four independent 2-input XNOR gates using standard CMOS silicon-gate technology, delivering rail-to-rail output swing and symmetrical rise/fall times. Its logic function outputs HIGH when both inputs match (00 or 11) and LOW otherwise, supporting wired-OR expansion via open-drain-compatible outputs in select configurations.

Designed for mixed-voltage system interfacing, it features input thresholds at 50% V_DD, hysteresis-free switching, and immunity to supply noise up to ±1 V. The device does not include Schmitt-trigger inputs, internal pull-ups, or bus-hold circuitry - all external biasing must be provided per application requirements.

FAQ

What logic function does the CD4086BM96G4 implement?

The CD4086BM96G4 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 function is used for equality detection, parity generation, and signal synchronization tasks. The CD4086BM96G4 maintains this behavior across its full 3 V to 18 V supply range and -55°C to +125°C operating temperature.

Is the CD4086BM96G4 pin-compatible with other CD4000-series logic devices?

Yes, the CD4086BM96G4 uses the standard 14-pin SOIC footprint shared across CD4000-series logic ICs like CD4001, CD4011, and CD4077. Pin 7 is GND, Pin 14 is V_DD, and the remaining pins follow TI's consistent dual-in-line assignment for quad-gate logic. This allows direct substitution in existing layouts designed for compatible CD4000-family parts, provided voltage and timing requirements align.

Does the CD4086BM96G4 include Schmitt-trigger inputs?

No, the CD4086BM96G4 does not include Schmitt-trigger inputs. Its inputs switch at approximately 50% of V_DD with no hysteresis. For noisy signal sources, external RC filtering or discrete hysteresis networks must be added. This differs from devices like CD4093B, which integrate Schmitt-trigger action. The CD4086BM96G4 relies on clean, well-sourced digital inputs for reliable operation.

What is the maximum recommended operating frequency for the CD4086BM96G4?

The CD4086BM96G4 is not characterized for continuous high-frequency operation. Its typical propagation delay is 100 ns at 5 V, implying a practical maximum toggle rate near 5 MHz under ideal conditions. However, it is intended for asynchronous, event-driven, or low-speed control logic - not clock distribution or data-path applications. For higher-speed needs, the CD4086BM96G4 should be replaced with purpose-built high-speed logic families.

Can the CD4086BM96G4 drive LED loads directly?

No, the CD4086BM96G4 is not rated to drive LEDs directly. Its output current capability is limited to ±1 mA at V_DD = 5 V, insufficient for typical indicator LEDs requiring 5–20 mA. Driving an LED would cause excessive voltage drop and potential output stage stress. To use the CD4086BM96G4 with LEDs, add a series current-limiting resistor and buffer transistor or dedicated LED driver. Always verify load conditions against the CD4086BM96G4's DC output specs.
