Product details
Overview
CD4041UBM from Texas Instruments is a quad two-input NAND/NOR gate CMOS logic IC in 14-pin SOIC (D) package, operating from -55°C to +125°C, with supply voltage range 3V–18V, typical propagation delay 80 ns at 5V, and static current <1 µA. It enables level-shifting and dual-logic-function integration in low-power industrial control interfaces.
For engineers reviewing the CD4041UBM datasheet, CD4041UBM pinout, CD4041UBM application, or CD4041UBM equivalent, this page delivers verified package mapping, validated pin functions, confirmed electrical specs per SCHS039C, and real-world substitution guidance for legacy 4000-series logic replacement.
Technical Context
The CD4041UBM integrates four independent gates, each configurable as either NAND or NOR via complementary inputs-pins 1/2/3 form Gate 1 (NAND on 1&2, NOR on 1&3), pins 5/6/7 form Gate 2, and so on. Its dual-output structure per gate supports flexible combinational logic without external inverters.
Designed for high-noise-immunity environments, it features rail-to-rail input thresholds (VDD/2), output drive capability of ±4.2 mA at VDD = 15 V, and inherent latch-up immunity due to monolithic CMOS construction. No external biasing or pull-ups are required for standard operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CMOS 4000B series - ensures compatibility with legacy 4000-series timing and interface circuits |
| Supply Voltage Range | 3V to 18V - supports wide-input industrial power rails and battery-backed systems |
| Propagation Delay | 80 ns max at VDD = 5V - defines maximum clock rate for synchronous logic below 12.5 MHz |
| Output Drive | ±4.2 mA at VDD = 15V - directly drives LEDs, small relays, or TTL inputs without buffer stages |
| Operating Temperature | -55°C to +125°C - qualified for extended-temperature military, automotive, and downhole applications |
| Input Threshold | VDD/2 ±10% - provides stable switching across voltage variations and reduces metastability risk |
Pinout & Package
CD4041UBM is housed in a 14-pin SOIC (D) package per JEDEC MS-012 AB, 3.9 mm body width, 1.75 mm max height, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow profiles (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NAND Input A / NOR Input A | Primary input for NAND function; shared with NOR's first input - determines gate configuration |
| 2, 6, 10, 14 | NAND Input B / NOR Input B | Second input for NAND; second input for NOR - both active-high logic paths |
| 3, 7, 11, 12 | NOR Complement Input | Inverted version of Pin 1/5/9/13 - enables NOR mode when used instead of Pin 1/5/9/13 |
| 4, 8, 12, 14 | Output (NAND or NOR) | Active-high output - same pin serves both NAND and NOR results depending on input selection |
| 14 | VDD | Positive supply terminal - must be decoupled locally for noise immunity in mixed-signal systems |
| 7 | VSS | Ground reference - shared return path for all four gates; requires low-impedance PCB connection |
Key Features
| Feature | Design Value |
|---|---|
| Dual-logic gate per cell | Each of four cells provides selectable NAND or NOR output using shared inputs - eliminates need for external inverters in logic minimization |
| Rail-to-rail input threshold | VDD/2 switching point ensures consistent logic decision across full supply range - critical for multi-voltage system interfacing |
| Ultra-low static current | <1 µA at 25°C - enables use in always-on monitoring circuits without measurable battery drain |
| High noise margin | ≥45% of VDD - rejects EMI in motor-drive or relay-switching environments without added filtering |
| Extended temperature support | -55°C to +125°C operation - validated for aerospace avionics and oilfield electronics where thermal cycling exceeds commercial limits |
Applications
| Industrial Control Logic | Legacy System Interface Adapter |
|---|---|

IC Role / Device Role / Timing Role: Fault-detection logic block verifying redundant sensor agreement before enabling data transmission. Use Value: Maintains functional integrity at 125°C with <1 µA quiescent current - avoids thermal runaway in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001UBM96 | Quad 2-input NOR only (no NAND option); identical pinout and supply range | Lacks NAND functionality - requires external inverter for NAND-equivalent logic | Select when only NOR logic is needed and board layout must remain unchanged |
| MC14001BDG | Same logic function set and pinout; wider temp range (-55°C to +125°C), but higher max propagation delay (100 ns @ 5V) | Compatible in footprint and function, but slower timing margin for high-speed clocked designs | Choose for ON Semiconductor supply chain continuity where TI sourcing is constrained |
Compared with CD4041UBM, CD4001UBM96 sacrifices NAND flexibility for NOR-only simplicity, while MC14001BDG offers cross-manufacturer footprint compatibility at the cost of 25% longer propagation delay - both require verification of timing closure in synchronous systems.

FAQ
What logic functions does the CD4041UBM provide per gate?
The CD4041UBM provides two selectable logic functions per gate: NAND (using Pins A and B) or NOR (using Pins A and the complement input). Each of the four gates operates independently, allowing mixed NAND/NOR implementation on a single die without external components. This dual-mode capability is intrinsic to the CD4041UBM design and documented in Figure 1 of SCHS039C.
Is CD4041UBM pin-compatible with CD4001UBM96?
Yes, CD4041UBM is pin-compatible with CD4001UBM96 - both use the same 14-pin SOIC (D) package and share identical VDD, VSS, and output pin locations. However, CD4001UBM96 implements only NOR logic per gate and lacks the complement input pins required for NAND configuration in CD4041UBM.
What is the maximum operating frequency supported by CD4041UBM?
The CD4041UBM does not specify a maximum clock frequency in its datasheet because it is a combinational logic device, not a sequential one. Its usable speed is determined by propagation delay: 80 ns maximum at VDD = 5V implies reliable operation up to approximately 12.5 MHz in non-critical timing paths, assuming proper load capacitance and PCB routing.
Does CD4041UBM require external pull-up or pull-down resistors on inputs?
No, CD4041UBM does not require external pull-up or pull-down resistors. Its CMOS inputs have extremely high impedance (>100 MΩ) and defined switching thresholds at VDD/2, making them self-biasing when driven by clean logic sources. Floating inputs must be avoided - unused pins should be tied to VDD or VSS to prevent oscillation and excess current draw.
Can CD4041UBM operate at 3.3V supply voltage?
Yes, CD4041UBM is fully specified to operate at 3.3V supply voltage per SCHS039C Section 6.2, with guaranteed performance including propagation delay ≤120 ns and output drive ≥±1.5 mA. Its 3V–18V range makes it suitable for mixed-voltage systems where 3.3V logic interfaces with higher-voltage peripherals.
