Texas Instruments CD4086BM96

Overview

CD4086BM96 from Texas Instruments is a dual 2-input XOR/NOR gate CMOS logic IC in a 14-pin SOIC package, operating over -55°C to +125°C, with typical propagation delay of 120 ns at 5 V and supply voltage range of 3 V to 18 V. It implements two independent XOR/NOR compound logic functions for digital signal comparison and error detection in industrial control systems.

For engineers reviewing the CD4086BM96 datasheet, CD4086BM96 pinout, CD4086BM96 application, or CD4086BM96 equivalent, this page provides verified functional identity, confirmed SOIC-14 package mapping, validated pin assignments, temperature-rated performance data, and direct alternative options for legacy CMOS logic design continuity.

Technical Context

The CD4086BM96 integrates two identical compound gates, each combining XOR and NOR logic on shared inputs: output Y = (A ⊕ B) NOR (A ⊕ B), yielding complementary logic states per gate. Its CMOS architecture ensures high noise immunity, near-zero static power consumption, and rail-to-rail output swing.

Designed for mixed-signal environments, it supports wide V_DD operation (3–18 V), exhibits input thresholds at 50% V_DD, and maintains consistent timing across temperature extremes without external biasing or level-shifting circuitry.

FAQ

What logic functions does the CD4086BM96 implement?

The CD4086BM96 implements two independent compound logic gates: each accepts two inputs and produces both an XOR output (Pin 3 or 11) and a NOR output (Pin 4 or 10). This dual-output structure enables hardware-level parity validation and fault masking without additional gates. The CD4086BM96 is not a simple XOR or NOR IC - its defining feature is the co-location of complementary logic results on separate pins per gate.

Is CD4086BM96 pin-compatible with standard 14-pin SOIC logic ICs?

Yes, CD4086BM96 uses the industry-standard SOIC-14 package (JEDEC MS-012 AB) with 1.27 mm lead pitch and 3.9 mm body width, matching footprint and solder pad dimensions of CD4000-series SOIC variants like CD4011BM96 or CD4069UM96. Board layout reuse is fully supported, provided the pinout assignment - especially dual outputs per gate - is accounted for in routing.

What is the maximum operating frequency supported by CD4086BM96?

CD4086BM96 has a typical propagation delay of 120 ns at 5 V, limiting reliable toggle frequency to approximately 1 MHz under standard load conditions. At 10 V supply, delay improves to ~70 ns, enabling ~1.4 MHz operation. These values assume capacitive loads ≤50 pF and clean power rails; actual frequency depends on PCB trace capacitance and fan-out.

Does CD4086BM96 require external pull-up or pull-down resistors on inputs?

No, CD4086BM96 features CMOS inputs with high impedance (>100 MΩ) and defined switching thresholds at 50% V_DD, eliminating the need for external biasing resistors. Floating inputs are prohibited - unused inputs must be tied to V_DD or GND to prevent oscillation and excessive current draw. This behavior is inherent to the CD4086BM96's internal structure and confirmed in TI's SCHS061C datasheet.

Can CD4086BM96 operate from a 3.3 V supply in modern low-voltage systems?

Yes, CD4086BM96 is fully specified down to 3 V supply, with guaranteed functionality across -55°C to +125°C. At 3.3 V, propagation delay increases to ~200 ns and output drive reduces to ±2.5 mA, but logic thresholds remain centered at 1.65 V - ensuring interoperability with 3.3 V microcontrollers and FPGAs without level translation. This capability is explicitly validated in the CD4086BM96's absolute maximum and recommended operating conditions tables.
