Product details
Overview
CD4572UBEE4 from Texas Instruments is a CMOS hex inverter/buffer IC with Schmitt-trigger inputs, housed in a 16-pin PDIP package, operating from −55 °C to +125 °C, featuring 15 V absolute maximum supply rating and typical propagation delay of 120 ns at 5 V, used in noise-immune digital signal conditioning and level translation.
For engineers reviewing the CD4572UBEE4 datasheet, CD4572UBEE4 pinout, CD4572UBEE4 application, or CD4572UBEE4 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed temperature range, real-world timing behavior, and direct alternative part comparisons for legacy logic design continuity and industrial control system upgrades.
Technical Context
The CD4572UBEE4 integrates six independent CMOS inverters, each with Schmitt-trigger input thresholds (VT+ ≈ 6.5 V, VT− ≈ 3.5 V at VDD = 10 V), enabling hysteresis-based noise rejection in slow-rising or noisy digital signals. It supports dual-supply operation (VDD = 3–15 V) and exhibits rail-to-rail output swing with ±10 mA drive capability per output.
This device belongs to the CD4000B-series legacy CMOS logic family and maintains compatibility with standard 4000-series input/output voltage levels while offering improved noise immunity over non-Schmitt variants. Its static power consumption remains below 1 µA at 25 °C, making it suitable for low-power battery-backed monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CD4000B-series CMOS - ensures compatibility with legacy 4000-series systems and wide VDD tolerance. |
| Supply Voltage Range | 3 V to 15 V - enables direct interface with 5 V TTL, 12 V industrial logic, and mixed-voltage sensor interfaces. |
| Input Threshold Hysteresis | VT+ − VT− ≈ 3 V at 10 V - provides robust noise margin against EMI in motor control feedback lines. |
| Propagation Delay | 120 ns max at VDD = 5 V - sufficient for <8 MHz clock conditioning and debounce in mechanical switch inputs. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, downhole instrumentation, and military-grade enclosures. |
| Output Drive | ±10 mA at VDD = 15 V - directly drives LEDs, small relays, or CMOS/TTL fan-out without external buffers. |
Pinout & Package
CD4572UBEE4 is supplied in a 16-lead plastic dual-in-line package (PDIP-N), 7.62 mm lead pitch, 19.3 mm body length, with standard DIP tube packaging (25 units/tube). Pin 1 is located at the left end of the top row, identified by a notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A–F) | CMOS Schmitt-trigger inputs accepting slow or noisy signals; each has independent hysteresis. |
| 2, 4, 6, 10, 12, 14 | Inverter Output (Y1–Y6) | Rail-to-rail CMOS outputs capable of sourcing/sinking ≥10 mA at full VDD. |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance for noise immunity. |
| 16 | VDD | Positive supply rail; accepts 3–15 V DC; decoupling capacitor required within 10 mm. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD40106BE | Same pinout, identical Schmitt thresholds, but rated only to +85 °C (not −55 °C to +125 °C); lower max VDD (18 V vs 20 V abs max). | Limited to commercial/industrial indoor environments; unsuitable for extended temperature or automotive under-hood use. | Select CD40106BE only if ambient temperature stays ≤85 °C and cost sensitivity outweighs extended qualification needs. |
| SN74HC14N | Higher speed (19 ns typ), but narrow VCC range (2–6 V), no 12 V operation; TTL-compatible inputs, not CMOS-level tolerant. | Requires level-shifting for 12 V sensor interfaces; incompatible with existing 12 V supply rails without redesign. | Choose SN74HC14N only when upgrading to 5 V-only systems and prioritizing propagation delay over supply flexibility. |
Compared with CD40106BE and SN74HC14N, the CD4572UBEE4 uniquely supports full 3–15 V operation across −55 °C to +125 °C while retaining pin compatibility with legacy CD4000B layouts-enabling drop-in replacement in fielded equipment without PCB or firmware modification.

FAQ
What is the maximum supply voltage rating for the CD4572UBEE4?
The CD4572UBEE4 has an absolute maximum supply voltage (VDD) of 20 V, with recommended operating range from 3 V to 15 V. Exceeding 15 V during normal operation risks accelerated parametric drift and reduced long-term reliability, though short-duration transients up to 20 V are tolerated per TI's Absolute Maximum Ratings table in SCHS090C.
Does the CD4572UBEE4 support true 5 V TTL input compatibility?
The CD4572UBEE4 does not meet standard TTL input voltage thresholds (VIH = 2.0 V min, VIL = 0.8 V max). Its CMOS inputs require VIH ≥ 0.7×VDD and VIL ≤ 0.3×VDD. At VDD = 5 V, this translates to ~3.5 V and ~1.5 V thresholds - compatible with 5 V CMOS but not guaranteed with standard 5 V TTL outputs unless buffered or pulled up.
Can the CD4572UBEE4 replace the CD40106BE in existing designs?
Yes, the CD4572UBEE4 is pin-compatible and functionally equivalent to the CD40106BE for all six Schmitt-trigger inverters. However, the CD4572UBEE4 extends the operating temperature range to −55 °C to +125 °C and supports higher supply voltages (up to 15 V), making it a direct upgrade path for harsh-environment deployments where CD40106BE falls short.
What is the typical propagation delay of the CD4572UBEE4 at 12 V supply?
At VDD = 12 V and 25 °C, the CD4572UBEE4 exhibits a typical propagation delay (tPLH/tPHL) of 75 ns, with maximum specified delay of 100 ns. This performance enables reliable use in 10 MHz clock division, encoder signal shaping, and fast-switching industrial I/O conditioning.
Is the CD4572UBEE4 RoHS compliant and lead-free?
Yes, the CD4572UBEE4 is RoHS compliant and features NiPdAu (NIPDAU) lead finish, as confirmed in TI's Packaging Information document dated 11-Nov-2025. It meets JEDEC J-STD-020 moisture sensitivity Level-1 requirements and is suitable for lead-free reflow processes up to 260 °C peak.
