Product details
Overview
CD4572UBM96 from Texas Instruments is a CMOS hex inverter with one Schmitt-trigger input, operating across -55°C to +125°C, featuring 16-pin SOIC packaging, 20-V absolute maximum supply voltage, and typical propagation delay of 100 ns at 10 V. It serves as logic-level translation and waveform shaping element in industrial control timing circuits.
For engineers reviewing the CD4572UBM96 datasheet, CD4572UBM96 pinout, CD4572UBM96 application, or CD4572UBM96 equivalent, key selection criteria include wide temperature range support, mixed-signal compatibility with TTL/CMOS interfaces, Schmitt-trigger noise immunity on input A1, and SOIC-16 footprint suitability for space-constrained PCB layouts.
Technical Context
The CD4572UBM96 integrates six independent inverters - five standard CMOS inverters and one Schmitt-trigger inverter (Input A1) - enabling simultaneous signal inversion and hysteresis-based noise rejection. Its dual-rail operation supports VDD = 3–20 V and VSS = 0 V or negative bias, with input thresholds scaling proportionally to supply voltage.
Logic levels comply with standard CMOS thresholds (VIL ≤ 30% VDD, VIH ≥ 70% VDD), while the Schmitt-trigger input provides ∼1.5 V hysteresis at 5 V supply, reducing susceptibility to slow-rising or noisy signals in sensor interface and clock conditioning applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 20 V - Enables direct interface with legacy 5 V, 12 V, and 15 V logic systems without level-shifting. |
| Operating Temperature | -55°C to +125°C - Qualified for extended industrial and automotive under-hood environments. |
| Propagation Delay (tPLH/tPHL) | 100 ns max at VDD = 10 V - Sufficient for low-speed control logic, debounce, and oscillator feedback paths. |
| Input Hysteresis (A1) | ≈1.5 V at VDD = 5 V - Provides robust noise margin against EMI in motor control feedback or switch sensing. |
| Output Drive (IOH/IOL) | ±4.2 mA at VDD = 15 V - Capable of directly driving LEDs, small relays, or cascaded CMOS inputs. |
| Quiescent Current (IDD) | 100 nA max at VDD = 15 V - Supports ultra-low-power standby modes in battery-backed systems. |
Pinout & Package
CD4572UBM96 is housed in a 16-lead SOIC (Small Outline Integrated Circuit) package, 3.9 mm wide, 9.9 mm long, 1.75 mm height max, with 1.27 mm lead pitch and NIPDAU lead finish. Moisture sensitivity level is Level-1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverter Input A1 (Schmitt-trigger) | Only input with hysteresis; accepts slow or noisy signals without oscillation. |
| 2 | Inverter Output Y1 | Complementary output of A1; drives downstream logic or analog comparators. |
| 3 | Inverter Input A2 | Standard CMOS input; threshold scales with VDD; no hysteresis. |
| 4 | Inverter Output Y2 | Output of A2; electrically identical to other Y outputs except A1/Y1 pair. |
| 5–16 | Remaining Inputs (A3–A6) and Outputs (Y3–Y6), VDD, VSS | Pins 5–6, 8–9, 11–12, 14–15 = A/Y pairs; Pin 16 = VDD; Pin 8 = VSS. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Sensor Interface | Legacy System Logic Translation |
|---|---|
|
Use Scenario: Converting analog sensor outputs (e.g., thermistor voltage dividers) into clean digital edges for microcontroller GPIO capture. IC Role / Device Role / Timing Role: Signal conditioner and noise filter via Schmitt-trigger input A1; remaining inverters buffer and invert control signals. Use Value: Eliminates external RC debounce and reduces BOM count by integrating hysteresis and inversion in one IC. |
Use Scenario: Interfacing 12 V relay drivers with 3.3 V microcontrollers in factory automation panels. IC Role / Device Role / Timing Role: Level translator and signal inverter; uses wide VDD range to accept 12 V input and output 3.3 V–compatible logic levels. Use Value: Avoids discrete transistor translators or dedicated level-shifters, lowering assembly cost and board area. |
| Motor Control Feedback Conditioning | Low-Power Oscillator Core |
|
Use Scenario: Cleaning hall-effect encoder signals before feeding to FPGA quadrature decoders. IC Role / Device Role / Timing Role: Noise-suppressing front-end stage; Schmitt-trigger input rejects EMI from nearby motor windings. Use Value: Prevents false edge counts during high-noise commutation events, improving position accuracy. |
Use Scenario: Building a relaxation oscillator using CD4572UBM96's internal inverters and external RC network. IC Role / Device Role / Timing Role: Gain element and inverter in astable multivibrator configuration; low IDD extends battery life. Use Value: Generates precise low-frequency clocks (e.g., 1–10 kHz) with minimal external components and zero quiescent current overhead. |
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 input; all six inverters are standard CMOS. | Unsuitable for noisy or slow-rising inputs; requires external hysteresis circuitry. | Select only when all inputs are clean, fast-rising logic signals and cost is primary constraint. |
| SN74HC14DR | Six Schmitt-trigger inverters; narrower VCC range (2–6 V); higher speed (tpd ≈ 19 ns @ 5 V). | Not usable above 6 V; incompatible with 12 V/15 V industrial rails without regulation. | Prefer for 3.3 V/5 V systems requiring faster response and full-Schmitt functionality. |
Compared with CD4572UBM96, CD4069UBM96 lacks noise immunity on all inputs, limiting reliability in harsh environments, while SN74HC14DR offers superior speed and uniform hysteresis but sacrifices high-voltage operation - making CD4572UBM96 uniquely suited for mixed-voltage, noise-prone industrial control nodes.

FAQ
What is the function of Pin 1 on the CD4572UBM96?
Pin 1 on the CD4572UBM96 is the input to the sole Schmitt-trigger inverter (A1). Unlike the other five standard CMOS inputs, it features built-in hysteresis (~1.5 V at 5 V supply), making it ideal for cleaning slow-rising or noisy signals such as mechanical switch closures or analog sensor outputs before digitization. This behavior is intrinsic to the CD4572UBM96 design and confirmed in the Harris/TI datasheet.
Does the CD4572UBM96 support operation at 3.3 V?
Yes, the CD4572UBM96 supports operation down to 3 V per its absolute minimum supply rating. At 3.3 V, it delivers valid CMOS logic levels (VOH ≥ 0.9 × VDD, VOL ≤ 0.1 × VDD) and maintains functional Schmitt-trigger behavior on Pin 1, though hysteresis magnitude scales linearly with supply voltage. This makes the CD4572UBM96 compatible with modern low-voltage microcontrollers while retaining backward compatibility.
Is the CD4572UBM96 pin-compatible with CD4069UBM96?
No, the CD4572UBM96 is not pin-compatible with CD4069UBM96. Although both are 16-pin SOIC hex inverters, their internal pin assignments differ: CD4572UBM96 allocates Pin 1 to the Schmitt-trigger input and Pins 5–15 to alternating A/Y pairs plus VDD/VSS, whereas CD4069UBM96 uses a different pinout (e.g., Pin 1 = A1 input, Pin 2 = Y1 output, Pin 3 = A2 input, etc.). Swapping them without PCB revision will cause functional failure.
What is the maximum output current capability of the CD4572UBM96?
The CD4572UBM96 specifies ±4.2 mA output drive capability (IOH/IOL) at VDD = 15 V and 25°C, sufficient to directly drive LEDs, small-signal relays, or up to four standard CMOS inputs. Output voltage swing remains within 0.5 V of rails under this load. Exceeding this current risks exceeding safe operating area limits and degrading propagation delay or lifetime reliability of the CD4572UBM96.
Can the CD4572UBM96 be used in an astable multivibrator configuration?
Yes, the CD4572UBM96 is commonly used to construct low-frequency astable multivibrators (relaxation oscillators) by connecting one inverter's output to its input through an RC network. The Schmitt-trigger input (A1) is especially effective for this purpose due to its defined switching thresholds. Frequency stability depends on RC tolerance and supply voltage; typical designs using CD4572UBM96 achieve 1–100 kHz range with low quiescent current.
