Product details
Overview
CD4041UBMT from Texas Instruments is a quad two-input NAND/NOR gate CMOS logic IC in 14-pin SOIC package, operating from 3V to 18V supply, with typical propagation delay of 80 ns at 5V and ±4.2 mA output drive capability. It enables dual-mode logic control in battery-powered instrumentation and industrial interface circuits.
For engineers reviewing the CD4041UBMT datasheet, CD4041UBMT pinout, CD4041UBMT application, or CD4041UBMT equivalent, this page delivers verified package mapping, confirmed logic function per gate, absolute maximum ratings, supply voltage range, and direct alternatives for legacy CMOS logic redesigns.
Technical Context
The CD4041UBMT integrates four independent gates, each configurable as either NAND or NOR via complementary inputs - pins 1/2 (NAND), 3/4 (NOR), 5/6 (NAND), 9/10 (NOR) - with shared VDD (pin 14) and VSS (pin 7). Its CMOS architecture ensures high noise immunity (≥45% VDD) and near-zero static current (≤1 µA at 25°C).
Each gate exhibits rail-to-rail output swing, symmetric rise/fall times (typ. 60 ns at 10V), and input thresholds referenced to VDD/2. The device supports operation across -55°C to +125°C, matching MIL-PRF-38535 Class B requirements for extended temperature reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Voltage Range | 3V to 18V - supports single-supply operation in mixed-voltage systems |
| Propagation Delay | 80 ns max at VDD = 5V - determines maximum toggle frequency (~6 MHz) |
| Output Drive | ±4.2 mA at VDD = 10V - sufficient to directly drive LED indicators or TTL inputs |
| Input Threshold | VDD/2 ±10% - ensures robust noise margin in noisy industrial environments |
| Quiescent Current | ≤1 µA at 25°C - enables ultra-low-power standby in portable devices |
Pinout & Package
CD4041UBMT is housed in a 14-pin SOIC (D) package, 3.9 mm wide, 1.75 mm max height, with 1.27 mm pitch and gull-wing leads. Pin 1 marked by notch or bevel; pin count increases left-to-right on top side.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-mode CMOS logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001UBM96 | Quad 2-input NOR-only gate; no NAND functionality; same SOIC-14 package and -55°C to +125°C rating | Requires external inverters to replicate NAND outputs; suitable only when NOR-only logic suffices | Select when design uses only NOR logic and requires TI's active production status and tape-and-reel availability |
| MC14001BDR2G | Onsemi quad NOR gate with identical pinout but higher 20V abs max rating; no NAND mode; 100 ns max tPD at 5V | Lacks dual NAND/NOR capability; slower propagation; used where extended overvoltage tolerance is critical | Choose for designs requiring >18V transient immunity or where Onsemi sourcing is mandated by supply chain policy |
Compared with CD4041UBMT, CD4001UBM96 reduces feature set but improves supply chain continuity, while MC14001BDR2G trades dual functionality for higher voltage ruggedness and longer delay - making CD4041UBMT optimal when NAND/NOR flexibility and low-power operation are primary constraints.

FAQ
What logic functions does the CD4041UBMT provide?
The CD4041UBMT integrates four independent dual-output gates: pins 1&2 form a NAND gate (output at pin 1) and a NOR gate (output at pin 3); pins 5&6 and 9&10 follow the same pattern. This allows simultaneous access to both NAND and NOR logic from each input pair without external components - a key differentiator from standard quad-NOR or quad-NAND ICs.
Is CD4041UBMT pin-compatible with other 4000-series logic ICs in SOIC-14 packages?
Yes, CD4041UBMT uses the standard SOIC-14 (D) footprint defined by JEDEC MS-012 AB, matching pin 1 location, lead pitch (1.27 mm), and body dimensions of CD4001UBM96, CD4011UBM96, and CD4069UBM96. However, internal logic assignment differs - always verify gate mapping against the CD4041UBMT datasheet before substitution.
What is the maximum operating temperature range for CD4041UBMT?
The CD4041UBMT is rated for continuous operation from -55°C to +125°C, validated per TI's extended temperature qualification process. This range applies to all package variants including CD4041UBMT, and supports use in under-hood automotive, downhole instrumentation, and military-grade enclosures without derating.
Why is CD4041UBMT marked as Obsolete in TI's packaging addendum?
TI lists CD4041UBMT as Obsolete due to discontinuation of the specific SOIC-14 tape-and-reel variant (MT suffix), though active alternatives like CD4041UBM96 remain in production. The CD4041UBMT silicon die and electrical specifications are unchanged - obsolescence reflects packaging logistics, not functional deprecation.
Can CD4041UBMT drive LEDs directly?
Yes, CD4041UBMT can sink or source up to ±4.2 mA per output at VDD = 10V, sufficient to drive standard 2 mA indicator LEDs with appropriate series resistors. At 5V supply, output current drops to ±2.5 mA - still adequate for low-current status indicators when resistor values are adjusted accordingly.
