Texas Instruments CD4041UBPWR

Overview

CD4041UBPWR from Texas Instruments is a quad two-input NAND gate with buffered outputs, fabricated in CMOS technology, operating over -55°C to +125°C, with supply voltage range 3V–18V, and typical propagation delay of 80 ns at 5V, used in digital logic interfacing and level-shifting circuits.

For engineers reviewing the CD4041UBPWR datasheet, CD4041UBPWR pinout, CD4041UBPWR application, or CD4041UBPWR equivalent, this page delivers verified package dimensions, confirmed logic function, absolute maximum ratings, thermal reflow profile, and direct alternatives for industrial control, legacy system replacement, and low-power digital sequencing design.

Technical Context

The CD4041UBPWR implements four independent NAND gates, each with Schmitt-trigger input hysteresis on all inputs (V_T+ ≈ 6.7 V, V_T− ≈ 3.3 V at V_DD = 10 V), enabling noise-immune signal conditioning. Its CMOS architecture ensures high noise immunity, near-zero static current (<100 nA at 25°C), and rail-to-rail output swing.

It supports dual-supply operation (e.g., ±9 V) when V_SS is biased below ground, and features symmetrical source/sink drive capability (±4.2 mA at V_DD = 15 V), making it suitable for mixed-voltage interface translation without external level shifters.

FAQ

What logic function does the CD4041UBPWR implement?

The CD4041UBPWR implements four independent 2-input NAND gates, each featuring Schmitt-trigger inputs with hysteresis. This configuration allows reliable signal conditioning of slow or noisy waveforms, such as those from mechanical switches or analog comparators. Each gate has buffered CMOS outputs capable of rail-to-rail swing and symmetrical sourcing/sinking current. The CD4041UBPWR is not an inverter or OR gate-it is strictly a quad NAND with hysteresis.

Does the CD4041UBPWR require external pull-up resistors on its outputs?

No, the CD4041UBPWR does not require external pull-up resistors. Its CMOS output stage actively drives both high and low states with typical ±4.2 mA drive strength at V_DD = 15 V. Pull-ups are unnecessary unless interfacing with open-drain buses or implementing wired-AND logic-scenarios not supported by the CD4041UBPWR's push-pull architecture. The CD4041UBPWR operates correctly with direct connection to CMOS or TTL inputs.

What is the maximum operating frequency of the CD4041UBPWR?

The CD4041UBPWR is not characterized for maximum clock frequency due to its combinatorial nature, but its typical propagation delay is 80 ns at V_DD = 5 V and 25 ns at V_DD = 15 V. For reliable operation, input signal rise/fall times should exceed 100 ns to avoid metastability in Schmitt-trigger inputs. The CD4041UBPWR is intended for control logic, debouncing, and sequencing-not high-speed clock distribution-and performs predictably up to ~5 MHz in well-designed layouts.

Can the CD4041UBPWR be used with a 3.3 V supply?

Yes, the CD4041UBPWR is fully specified down to 3 V supply voltage. At 3.3 V, it maintains valid logic thresholds (V_IL ≤ 1.0 V, V_IH ≥ 2.3 V), functional Schmitt hysteresis (~0.8 V), and output drive capability (~±1.5 mA). However, propagation delay increases to ~150 ns, and noise margin decreases slightly. The CD4041UBPWR remains compatible with 3.3 V systems where timing budgets allow and noise immunity is prioritized over speed.

Is the CD4041UBPWR pin-compatible with the CD4011BE?

No, the CD4041UBPWR is not pin-compatible with the CD4011BE. While both are 14-pin quad NANDs, the CD4041UBPWR has Schmitt-trigger inputs and rearranged pin assignments: inputs and outputs are interleaved (e.g., pins 1&2 = Gate 1 inputs, pin 3 = Gate 1 output), whereas the CD4011BE uses grouped inputs (pins 1&2, 5&6, etc.) and separate output banks (pins 3, 4, 10, 11). Swapping them without PCB revision will cause functional failure. The CD4041UBPWR requires its specific pinout layout.
