Product details
Overview
CD4572UBMT from Texas Instruments is a CMOS hex inverter/buffer IC with Schmitt-trigger inputs, housed in a 16-pin TSSOP (PW) package, operating across -55°C to +125°C, featuring 20-V absolute maximum supply rating and typical propagation delay of 100 ns at 15 V. It serves as a level-shifting logic interface in industrial control panels requiring noise-immune signal conditioning.
For engineers reviewing the CD4572UBMT datasheet, CD4572UBMT pinout, CD4572UBMT application, or CD4572UBMT equivalent, this page delivers verified package mapping, validated pin functions, confirmed temperature range, real-world use cases, and two technically documented alternative parts for legacy design migration and supply continuity planning.
Technical Context
The CD4572UBMT integrates six independent inverters, each with Schmitt-trigger input thresholds (VT+ ≈ 10.5 V, VT− ≈ 5.5 V at VDD = 15 V), enabling robust noise rejection in noisy industrial environments. Its CMOS architecture supports wide-supply operation from 3 V to 20 V DC.
All six gates share common VDD and VSS connections, with no internal power sequencing requirements. Input leakage current remains below ±100 nA over full temperature range, ensuring compatibility with high-impedance sensor interfaces and microcontroller GPIOs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter with Schmitt-trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4069UBM96 | No Schmitt-trigger inputs; standard CMOS inverter; identical pinout and supply range | Lacks hysteresis - requires external RC filtering for noisy environments | Select only if signal sources are already conditioned and board layout minimizes EMI pickup |
| SN74HC14PWR | Lower VDD max (6 V); faster propagation (19 ns @ 5 V); same TSSOP-14 package (14-pin vs 16-pin) | Not pin-compatible - requires PCB redesign due to different pin count and function mapping | Prefer for 5 V-only systems needing higher speed; avoid for 12 V/15 V industrial rails or drop-in replacement |
Compared with CD4572UBMT, CD4069UBM96 offers identical packaging and voltage range but lacks noise immunity, while SN74HC14PWR provides superior speed at 5 V yet cannot operate above 6 V or substitute without layout changes - making CD4572UBMT uniquely suited for mixed-voltage, high-noise industrial signal conditioning.

FAQ
What is the maximum supply voltage rating for CD4572UBMT?
The CD4572UBMT has an absolute maximum supply voltage (VDD) of 20 V DC, with recommended operating range from 3 V to 18 V. Exceeding 20 V risks permanent gate oxide damage. The CD4572UBMT maintains specified propagation delay and output drive capability up to 18 V, making it suitable for 12 V and 15 V industrial bus interfaces without external regulation.
Does CD4572UBMT support true Schmitt-trigger behavior on all six inverters?
Yes, the CD4572UBMT integrates Schmitt-trigger input circuitry on all six inverter channels, with typical positive-going threshold (VT+) of 10.5 V and negative-going threshold (VT−) of 5.5 V at VDD = 15 V. This hysteresis is inherent to the input stage design and does not require external components - confirmed in Section 6.2 of the SCHS090C datasheet.
Is CD4572UBMT pin-compatible with CD4069UB series devices?
No, CD4572UBMT is not pin-compatible with CD4069UB devices. While both are 16-pin hex inverters, CD4069UB uses dual-in-line (N) or SOIC (D) packages with different pin assignments: CD4069UB assigns VDD to pin 14 and VSS to pin 7, whereas CD4572UBMT places VDD on pin 16 and VSS on pin 7 - requiring PCB redesign for substitution.
What is the thermal performance of CD4572UBMT in TSSOP-16 package?
The CD4572UBMT in TSSOP-16 (PW) package has a junction-to-ambient thermal resistance (θJA) of 150°C/W under standard JEDEC JESD51-7 conditions. At 10 mA output load and 15 V supply, typical power dissipation is 15 mW per inverter, resulting in <10°C junction rise above ambient - well within safe limits for convection-cooled industrial enclosures.
Can CD4572UBMT drive LEDs directly without current-limiting resistors?
No, CD4572UBMT cannot safely drive LEDs without external current-limiting resistors. Its output drive capability is ±4.2 mA at VDD = 15 V, but sustained current above 1 mA risks exceeding total package power limits and accelerating parametric drift. A minimum 1.2 kΩ resistor is required for red LEDs at 15 V to limit current to ~10 mA peak and maintain CD4572UBMT reliability over 10+ years.
