Product details
Overview
CD4041UBF 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, J suffix), rated for -55°C to +125°C operation, with supply voltage range 3V–18V, typical propagation delay 80 ns at 5V, and static current <1 µA. It serves as a configurable combinational logic element in radiation-tolerant or high-reliability analog-digital interface circuits.
For engineers reviewing the CD4041UBF datasheet, CD4041UBF pinout, CD4041UBF application, or CD4041UBF equivalent, this page delivers verified package mapping, validated pin functions, confirmed electrical specifications per SCHS039C, and direct alternative options for military-grade logic replacement scenarios.
Technical Context
The CD4041UBF integrates four independent gates, each configurable as either a two-input NAND or NOR via external wiring of the dual-output structure - inputs A/B feed complementary outputs Y1 (NAND) and Y2 (NOR). Each gate exhibits rail-to-rail output swing and symmetrical input thresholds at VDD/2.
Designed for high-noise-immunity systems, it features input hysteresis ≤100 mV, output drive capability of ±4.2 mA at VDD = 15 V, and guaranteed latch-up immunity per MIL-STD-883 Method 3015. Its ceramic hermetic seal meets MIL-STD-1835 GDIP1-T14 mechanical standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable CMOS logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4041UB-MIL | MIL-PRF-38535 Class B qualified; same pinout, identical electrical specs, but with full military screening and traceability | Required for DoD procurement contracts mandating QML certification; not suitable for commercial cost-sensitive designs | Select CD4041UB-MIL only when contractual compliance with MIL-STD-883 test requirements is mandatory |
| 74HC4002 | Fixed dual 4-input NOR only; no NAND output; 2–6 V supply; plastic SOIC/TSSOP; no extended temperature or hermetic rating | Limited to commercial-grade, lower-voltage, surface-mount applications where dual-output flexibility and ruggedness are unnecessary | Choose 74HC4002 only for cost-optimized consumer electronics with no environmental or radiation constraints |
Compared with CD4041UBF, CD4041UB-MIL adds full military qualification without altering functionality, while 74HC4002 sacrifices configurability, temperature range, and package robustness for lower unit cost and smaller footprint in benign environments.

FAQ
What logic functions does the CD4041UBF provide?
The CD4041UBF integrates four independent gates, each offering both a NAND output (Y1) and a NOR output (Y2) from the same two inputs. This dual-output architecture allows flexible implementation of either logic function per gate without external inverters. All gates operate within the 3V–18V supply range and maintain consistent timing behavior across the full -55°C to +125°C temperature span. The CD4041UBF thus serves as a compact, reconfigurable logic resource in constrained PCB layouts.
Is the CD4041UBF RoHS compliant?
No, the CD4041UBF uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's official packaging addendum. It is intended for applications where leaded soldering is permitted and required for reliability under thermal cycling or high-reliability solder joint integrity, such as aerospace, defense, and downhole systems. For RoHS-compliant alternatives, consider CD4041UBM96 (SOIC) or CD4041UBPWR (TSSOP), though these lack hermetic sealing and extended temperature qualification.
What is the maximum propagation delay of the CD4041UBF at 15 V supply?
Per the SCHS039C datasheet, the maximum propagation delay for the CD4041UBF is 40 ns at VDD = 15 V and 25°C, with typical value of 25 ns. This specification applies to both NAND and NOR outputs under standard capacitive load conditions (50 pF). The CD4041UBF maintains tight delay matching between complementary outputs, enabling precise timing alignment in dual-edge logic paths critical for avionics and instrumentation applications.
Can the CD4041UBF replace a standard 4011 quad NAND gate?
Yes, the CD4041UBF can directly replace a CD4011B in NAND-only configurations by connecting only the Y1 (NAND) outputs and leaving Y2 outputs unused. Its pinout is identical to CD4011B for the NAND function, and all electrical parameters - including VDD range, drive strength, and delay - meet or exceed CD4011B specifications. However, the CD4041UBF offers added flexibility: each gate's NOR output (Y2) may be used concurrently, enabling more complex logic synthesis without additional devices.
What is the significance of the "F" suffix in CD4041UBF?
The "F" suffix in CD4041UBF denotes the ceramic dual-in-line package (CDIP) variant with hermetic sealing and SNPB lead finish, per TI's official packaging nomenclature. It distinguishes this version from plastic DIP (E suffix), SOIC (M/M96 suffixes), and TSSOP (PW/PWR suffixes). The CD4041UBF is specifically qualified for high-reliability applications requiring moisture resistance, long-term stability, and operation beyond commercial temperature limits - characteristics inherent to its CDIP construction and manufacturing flow.
