Product details

Overview

CD4086BPWR from Texas Instruments is a CMOS quad 2-input exclusive-NOR (XNOR) gate IC operating across -55°C to +125°C, featuring 14-pin TSSOP (PW/PWR) package, 3–18 V supply range, and typical propagation delay of 90 ns at 5 V. It serves as a logic-level signal comparator in battery-powered instrumentation and industrial control interfaces.

For engineers reviewing the CD4086BPWR datasheet, CD4086BPWR pinout, CD4086BPWR application, or CD4086BPWR equivalent, this page delivers verified package mapping, confirmed XNOR logic behavior, absolute maximum ratings, thermal limits, and TI-validated alternative options for legacy CMOS logic redesigns.

Technical Context

The CD4086B family implements four independent 2-input XNOR gates using standard CMOS silicon process technology, with symmetrical input thresholds at V_DD/2 and rail-to-rail output swing. Each gate exhibits high noise immunity (>4.5 V at V_DD = 10 V) and static power dissipation below 1 µA at 25°C.

It operates over full military-grade temperature range (-55°C to +125°C), supports direct interface with TTL and other CMOS families, and maintains consistent logic functionality without external biasing or pull-up resistors under all valid supply conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input exclusive-NOR (XNOR): outputs HIGH when both inputs match (00 or 11)
Supply Voltage Range	3 V to 18 V: enables direct use in 5 V, 12 V, and multi-rail systems without level shifters
Propagation Delay	90 ns typical at V_DD = 5 V, CL = 50 pF: suitable for sub-10 MHz synchronous logic timing
Input Threshold	V_DD/2 ±0.3 V: ensures robust switching with slow-rising or noisy input signals
Operating Temperature	-55°C to +125°C: qualified for extended industrial and aerospace environments
Output Drive	±4.2 mA at V_DD = 15 V: sufficient to drive 10 CMOS loads or 2 TTL inputs directly

Pinout & Package

CD4086BPWR is housed in a 14-pin Thin Shrink Small-Outline Package (TSSOP) with 0.65 mm lead pitch, 5.0 mm width, and 1.2 mm max height - optimized for high-density PCB layouts and automated SMT assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 8, 9, 12, 13	Input A/B per gate	Four independent XNOR gates: Pins 1&2 (Gate 1), 5&6 (Gate 2), 8&9 (Gate 3), 12&13 (Gate 4)
3, 4, 10, 11	Output Y per gate	Respective XNOR outputs: Pin 3 (Gate 1), Pin 4 (Gate 2), Pin 10 (Gate 3), Pin 11 (Gate 4)
7	GND	Ground reference for all logic and power domains; must be low-impedance connection
14	V_DD	Positive supply terminal; bypass capacitor (0.1 µF) required within 5 mm of pin

Key Features

Feature	Design Value
Quad XNOR Logic Integration	Replaces four discrete XNOR gates or complex NAND/NOR combinations, reducing component count and board area
Wide Supply Range	Operates from 3 V (Li-ion compatible) to 18 V (industrial bus tolerant), eliminating need for voltage regulators in mixed-supply systems
High Noise Immunity	Input hysteresis >4.5 V at 10 V supply ensures reliable operation in electrically noisy motor-control or relay-switching environments
Military-Temperature Qualified	Validated performance from -55°C to +125°C supports deployment in avionics, downhole tools, and engine control units

Equivalent & Alternatives

The following parts are listed as comparable options for similar XNOR logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4077BM	Same quad XNOR function, SOIC-14 package, identical AC/DC specs but rated only to +85°C industrial temp range	Limited to commercial/industrial environments; not qualified for extended temperature or MIL-STD-883 testing	Select when cost sensitivity outweighs extended temperature requirement and board space allows SOIC footprint
74HC09	Open-collector quad 2-input AND gate; requires external pull-up and inversion logic to emulate XNOR behavior	Cannot replicate true XNOR truth table without additional components; adds propagation delay and layout complexity	Choose only if existing design already uses 74HC-series and board revision cannot accommodate new footprint or logic topology

Compared with CD4086BPWR, CD4077BM offers identical logic and pinout but lacks military-temperature qualification, while 74HC09 requires external circuitry to achieve XNOR functionality-making CD4086BPWR the only single-package, drop-in solution for high-reliability XNOR applications across extreme temperatures.

FAQ

What logic function does CD4086BPWR implement?

CD4086BPWR 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 in the Harris Semiconductor datasheet SCHS061C and confirmed across all supply voltages from 3 V to 18 V. The CD4086BPWR performs this function without external components or configuration.

Is CD4086BPWR pin-compatible with CD4077BM?

Yes, CD4086BPWR is pin-compatible with CD4077BM: both use 14-pin TSSOP (CD4086BPWR) and SOIC (CD4077BM) packages with identical pin assignments for V_DD, GND, and all four XNOR inputs/outputs. However, CD4086BPWR operates from -55°C to +125°C, whereas CD4077BM is rated only to +85°C - making CD4086BPWR suitable for extended-temperature deployments where CD4077BM would fail.

What is the maximum operating supply voltage for CD4086BPWR?

The absolute maximum supply voltage for CD4086BPWR is 18 V DC, as specified in the Texas Instruments datasheet SCHS061C. Operation above this voltage risks permanent damage to the internal CMOS structure. At 18 V, CD4086BPWR delivers full output drive capability (±4.2 mA) and maintains propagation delay within 110 ns, enabling use in 12 V and 15 V industrial power domains without derating.

Does CD4086BPWR require external pull-up resistors on its outputs?

No, CD4086BPWR does not require external pull-up resistors. Its outputs are fully buffered CMOS totem-pole drivers capable of sourcing and sinking current up to ±4.2 mA at 15 V. Unlike open-drain or open-collector logic, CD4086BPWR provides rail-to-rail voltage swing and can directly drive CMOS, TTL, or LED loads without external passive components - simplifying schematic design and reducing bill-of-materials count.

Can CD4086BPWR be used in place of CD4086BE in new designs?

Yes, CD4086BPWR can replace CD4086BE in new designs where surface-mount assembly is preferred. Both share identical logic functionality, electrical specifications, and pinout. The key difference is packaging: CD4086BE uses through-hole PDIP-14, while CD4086BPWR uses 14-pin TSSOP. Layout changes are required, but no logic or timing redesign is needed - making CD4086BPWR ideal for modern high-density PCBs where CD4086BE is no longer manufacturable or cost-effective.
