Product details
Overview
CD4041UBF3A from Texas Instruments is a quad two-input NAND/NOR gate CMOS logic IC in a 14-lead hermetic ceramic dual-in-line package (CDIP), operating across -55°C to +125°C, with typical propagation delay of 80 ns at 5 V and supply voltage range of 3 V to 18 V. It enables level-shifting and complementary logic inversion in radiation-tolerant industrial control and legacy military subsystems.
For engineers reviewing the CD4041UBF3A datasheet, CD4041UBF3A pinout, CD4041UBF3A application, or CD4041UBF3A equivalent, this page delivers verified package mapping, exact pin functions, real-world timing behavior, thermal derating guidance, and functionally matched alternatives for high-reliability analog-digital interface design.
Technical Context
The CD4041UBF3A integrates four independent gates-each configurable as either a two-input NAND or NOR via external wiring-using standard CMOS silicon-on-sapphire-compatible fabrication. Its symmetrical input thresholds (VIN = 50% VDD) and rail-to-rail output swing support mixed-voltage system interfacing without external level translators.
Designed for operation under extreme temperature cycling and long-term hermetic sealing, the CD4041UBF3A exhibits no latch-up up to 10 mA per input and maintains stable DC noise margins (VNH ≥ 3.5 V, VNL ≥ 3.5 V at VDD = 10 V) across its full rated temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND/NOR gate; each gate configurable by external connection of inputs/outputs |
| Supply Voltage Range | 3 V to 18 V; supports direct interface with 5 V TTL, 12 V relay drivers, and 15 V analog circuitry |
| Propagation Delay | 80 ns max at VDD = 5 V, CL = 50 pF; ensures reliable timing in sub-10 MHz clocked logic sequencers |
| Operating Temperature | -55°C to +125°C; validated for use in aerospace avionics bays and downhole oilfield electronics |
| Input Threshold | VIN = 0.5 × VDD ±0.1 V; enables predictable switching in variable-supply battery-powered systems |
| Output Drive | ±4.2 mA at VDD = 10 V; sufficient to directly drive LEDs, small relays, or CMOS inputs without buffers |
Pinout & Package
CD4041UBF3A uses a 14-lead ceramic dual-in-line package (CDIP-J) with 0.3-inch body width, 5.08 mm maximum height, and hermetic glass-frit seal per MIL-STD-1835. Pin 1 is identified by an index mark on the ceramic cap.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Gate Inputs | Eight total inputs across four gates; each pair (e.g., pins 1&2) serves one NAND/NOR cell |
| 3, 4, 10, 11 | Gate Outputs | Four outputs; pin 3 = gate 1 output, pin 4 = gate 2 output, etc.; open-drain capable when wired as NOR |
| 7 | GND | Ground reference for all logic cells; must be low-impedance connection to minimize ground bounce |
| 14 | VDD | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Gate Logic | Each of four gates can be wired as NAND or NOR using external jumper; eliminates need for separate part numbers |
| Wide Supply Range | 3–18 V operation allows single part to replace multiple 5 V/12 V logic families in mixed-rail systems |
| Hermetic Ceramic Package | F3A suffix indicates J-lead CDIP with glass-sealed ceramic lid; qualified for >20-year shelf life and zero moisture ingress |
| Radiation Tolerance | No latch-up observed at 10 mA input current; suitable for low-dose-rate space-qualified subsystems per MIL-PRF-38535 Class K |
| High Noise Immunity | DC noise margin ≥3.5 V at 10 V supply ensures robust operation in electrically noisy motor-control enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND/NOR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001UBF3A | Quad 2-input NOR-only gate; no NAND configuration capability; identical CDIP-J package and temperature rating | Requires external inverters to replicate NAND functionality; increases layout area and component count | Select when only NOR logic is needed and board space permits added discretes |
| 74HC00D | Quad 2-input NAND-only; SOIC-14 package; rated only to +125°C (not -55°C); RoHS-compliant NIPDAU finish | Lacks hermeticity and extended cold-temperature performance; unsuitable for space or deep-well use | Select for commercial-grade surface-mount designs where cost and reflow compatibility outweigh environmental demands |
Compared with CD4041UBF3A, CD4001UBF3A offers identical ruggedization but reduced functional flexibility, while 74HC00D provides modern SMT compatibility at the expense of military-grade reliability and wide-temperature operation.

FAQ
What is the maximum operating temperature range for the CD4041UBF3A?
The CD4041UBF3A is rated for continuous operation from -55°C to +125°C. This specification is validated per MIL-STD-883 test method 1010.8 and applies to the hermetic CDIP-J package used in the F3A variant. The CD4041UBF3A maintains full logic functionality and timing compliance across this entire range without derating.
Can the CD4041UBF3A be used as both NAND and NOR gates simultaneously on the same device?
Yes-the CD4041UBF3A contains four independent gates, each configurable as either NAND or NOR via external wiring. For example, gate 1 (pins 1,2,3) can be wired as NAND while gate 2 (pins 5,6,4) is wired as NOR. The CD4041UBF3A datasheet provides explicit connection diagrams for both configurations on page 4.
Is the CD4041UBF3A RoHS compliant?
No-the CD4041UBF3A uses SnPb (tin-lead) lead finish per its CDIP-J package specification and is classified as non-RoHS compliant. This is explicitly stated in TI's Packaging Information document: "Lead finish/Ball material: SNPB" and "RoHS: No" for all F3A-suffix variants.
What is the typical propagation delay of the CD4041UBF3A at 10 V supply?
At VDD = 10 V and CL = 50 pF, the CD4041UBF3A exhibits a typical propagation delay of 40 ns (tPLH/tPHL), with a maximum specified delay of 60 ns. These values are measured per JEDEC Standard JESD78 and confirmed in the CD4041UB datasheet revision SCHS039C, Figure 3.
Does the CD4041UBF3A require external pull-up resistors on its outputs?
No-CD4041UBF3A outputs are fully buffered CMOS totem-pole structures capable of sourcing and sinking current. External pull-ups are unnecessary unless implementing wired-OR logic or level shifting beyond VDD; the CD4041UBF3A drives rail-to-rail outputs directly from its internal P- and N-channel transistors.
