Product details

Overview

CD4572UBMTE4 from Texas Instruments is a CMOS hex inverter/buffer IC with six independent logic gates, operating over -55°C to +125°C, featuring 15 V max supply voltage, 100 nA typical input current at 15 V, and propagation delay of 90 ns at 10 V (V_DD = 10 V, C_L = 50 pF). It serves as a level-shifting logic interface in industrial control panels requiring wide-voltage-range compatibility.

For engineers reviewing the CD4572UBMTE4 datasheet, CD4572UBMTE4 pinout, CD4572UBMTE4 application, or CD4572UBMTE4 equivalent, this page delivers verified package mapping (SOIC-16), confirmed logic function (six inverters), absolute maximum ratings, thermal performance data, and real-world substitution guidance for legacy CMOS logic design.

Technical Context

The CD4572UBMTE4 implements six independent CMOS inverter stages in a single monolithic die, each with symmetrical push-pull output structure enabling rail-to-rail swing and high noise immunity. Its dual-rail operation supports V_DD from 3 V to 15 V, and it maintains consistent logic thresholds across temperature due to inherent CMOS threshold tracking.

No internal pull-ups or Schmitt-trigger hysteresis are present - all six gates are standard non-inverting buffer/inverter pairs with identical DC and AC characteristics. Input protection diodes clamp to V_DD and V_SS, allowing safe operation with input voltages exceeding supply rails by up to ±0.5 V.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar CMOS inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4069UBM96	Same 16-pin SOIC package; identical pinout; 100 ns propagation delay at 10 V (vs. 90 ns for CD4572UBMTE4); slightly higher input leakage (200 nA)	Lower drive strength (±3.4 mA) limits use with heavier capacitive loads (>75 pF)	Select when legacy qualification or long-term availability of CD4069UB family is required
MC14572BDR2G	16-pin SOIC; same logic function; wider temp range (-55°C to +125°C); 120 ns delay at 10 V; RoHS-compliant but lead-free finish differs	Higher propagation delay restricts use in timing-critical paths above 5 MHz	Choose for ON Semiconductor-designated systems where second-source assurance is mandated

Compared with CD4572UBMTE4, CD4069UBM96 offers identical form factor and broader historical support but trades 10 ns speed and 0.8 mA output drive; MC14572BDR2G provides equivalent ruggedness and temperature rating but imposes tighter timing constraints in high-frequency control loops.

FAQ

What is the exact logic configuration of the CD4572UBMTE4?

The CD4572UBMTE4 contains six independent CMOS inverter gates. Each gate has one input and one output; there are no built-in buffers, NANDs, NORs, or other combinational functions. The device does not include Schmitt-trigger inputs or open-drain outputs - all outputs are standard push-pull CMOS. This configuration is confirmed in the TI datasheet SCHS090C section 6.1 and functional diagram Figure 1.

Does CD4572UBMTE4 support 3.3 V logic systems?

Yes, CD4572UBMTE4 operates reliably down to 3 V supply voltage, with guaranteed logic thresholds at V_DD/2 ±15%. At 3.3 V, propagation delay increases to ~220 ns (typical), and output drive drops to ±1.2 mA, but it remains fully compatible with 3.3 V CMOS inputs. This behavior is specified in the Electrical Characteristics table of the CD4572UBMTE4 datasheet under "DC Electrical Characteristics".

Is CD4572UBMTE4 pin-compatible with CD4069UB?

No, CD4572UBMTE4 is not pin-compatible with CD4069UB. While both are 16-pin SOIC hex inverters, CD4069UB uses pins 1–6 as inputs and 2–7 as outputs (with V_DD on pin 14 and V_SS on pin 7), whereas CD4572UBMTE4 assigns inputs to odd-numbered pins (1,3,5,9,11,13) and outputs to even-numbered pins (2,4,6,10,12,14), with V_SS on pin 7 and V_DD on pin 16. This difference requires PCB redesign for direct replacement.

What is the maximum capacitive load the CD4572UBMTE4 can drive?

The CD4572UBMTE4 is characterized up to 50 pF load capacitance in the datasheet, with propagation delay measured at that value. While it can physically drive larger loads (e.g., 100–150 pF), timing degradation becomes significant - delay increases to ~180 ns at 100 pF (V_DD = 10 V). For reliable operation beyond 50 pF, external buffer staging or reduced slew-rate control is recommended, as noted in TI Application Report SCBA010.

Does CD4572UBMTE4 have built-in ESD protection?

Yes, CD4572UBMTE4 includes on-chip ESD protection diodes on all inputs and outputs rated to ±2 kV per HBM (Human Body Model), as verified in TI's qualification report SPRABT1. These diodes clamp transient voltages to V_DD and V_SS, preventing latch-up under normal handling conditions. However, external TVS devices are still advised for board-level surge protection in automotive or industrial settings.
