Product details
Overview
MC14584BCP from onsemi is a hex Schmitt trigger IC built with MOS P-channel and N-channel enhancement-mode devices in a monolithic CMOS structure. It provides six independent Schmitt-trigger inverters with hysteresis (VH = 0.25–1.7 V), operates from 3.0 V to 18 V, and delivers ±0.36–8.8 mA output drive at VDD = 5–15 V. It is used to square up slow-rising waveforms in noise-prone sensor interfaces and clock conditioning circuits.
For engineers reviewing the MC14584BCP datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated SOIC-14 pin mapping, real-world use cases in industrial timing and signal conditioning, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MC14584BCP implements six identical Schmitt-trigger inverter stages, each with asymmetric input thresholds (VT+ = 1.7–10.5 V, VT− = 1.5–9.9 V) and hysteresis voltage (VH = 0.21–1.5 V) dependent on supply voltage. Its CMOS architecture enables ultra-low quiescent current (IDD = 0.5–30 µA at 25 °C) and high noise immunity across −55 °C to +125 °C ambient range.
Each inverter drives capacitive loads up to 50 pF with propagation delays of 40–250 ns and rise/fall times of 40–200 ns at VDD = 5–15 V. Input protection includes double diodes per pin, and unused inputs must be tied to VSS or VDD to prevent floating-state instability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 18 V DC - supports wide-input industrial and automotive power rails without external regulation. |
| Hysteresis Voltage (VH) | 0.21 V to 1.5 V - ensures robust noise rejection for signals with slow edges or EMI coupling. |
| Output Drive Current | ±0.36 mA to ±8.8 mA - sufficient to directly drive TTL loads or interface with microcontroller GPIOs. |
| Propagation Delay | 40 ns to 250 ns - enables reliable timing in sub-MHz digital signal conditioning and debouncing. |
| Quiescent Current | 0.5 µA to 30 µA - allows battery-powered operation in low-duty-cycle sensor wake-up circuits. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive and industrial control environments. |
| Input Protection | Double diode clamping on all inputs - prevents latch-up and damage from transient overvoltage events. |
Pinout & Package
MC14584BCP is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) with body dimensions 8.55 mm × 3.80 mm × 1.35 mm (Case 751A), Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (IN1–IN6) | CMOS Schmitt-trigger input pins - accept slow-rising analog-like signals and convert to clean digital logic levels. |
| 2, 4, 6, 8, 10, 12 | Output (OUT1–OUT6) | Inverted, hysteresis-shaped outputs - provide rail-to-rail swing and drive capability for downstream logic or analog comparators. |
| 7 | VSS | Ground reference - must be connected to system common ground; unused inputs require tie to VSS or VDD. |
| 14 | VDD | Positive supply - powers all six inverters; decoupling capacitor recommended near pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 V operation eliminates need for level-shifting in mixed-voltage systems. |
| High Noise Immunity | Programmable hysteresis via VDD enables tailored noise margin for specific signal integrity requirements. |
| Low-Power CMOS | Sub-microamp quiescent current extends battery life in always-on sensor monitoring nodes. |
| TTL Load Compatibility | Capable of driving two low-power TTL loads - simplifies interface with legacy logic families. |
| Pb-Free & RoHS | Compliant with environmental regulations and compatible with lead-free reflow soldering profiles. |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Input Debouncing |
|---|---|
|
Use Scenario: Cleaning noisy analog outputs from thermistors, potentiometers, or mechanical switches before ADC sampling or GPIO detection. IC Role / Device Role / Timing Role: Schmitt-trigger inverter - converts slow, noisy analog transitions into sharp, jitter-free digital edges. Use Value: Eliminates software debounce routines and reduces MCU interrupt latency by delivering deterministic edge timing with 40–250 ns delay. |
Use Scenario: Debouncing push-button or relay contacts feeding microcontroller interrupt pins in factory HMIs or PLC I/O modules. IC Role / Device Role / Timing Role: Six independent hysteresis inverters - each conditions one switch channel with consistent threshold behavior across temperature. Use Value: Ensures reliable contact bounce suppression without external RC networks, reducing BOM count and PCB area. |
| Waveform Squaring for Clock Recovery | Legacy Logic Interface Translation |
|
Use Scenario: Converting sine-wave oscillator outputs or distorted clock signals into clean square waves for FPGA clock domain synchronization. IC Role / Device Role / Timing Role: Signal shaping element - adds controlled hysteresis to reject amplitude noise while preserving edge timing integrity. Use Value: Enables stable clock recovery from low-SNR sources (e.g., crystal oscillators with aging drift or EMI-coupled traces). |
Use Scenario: Interfacing 5 V or 12 V legacy TTL/CMOS logic with modern 3.3 V microcontrollers in industrial retrofits. IC Role / Device Role / Timing Role: Level-tolerant buffer - accepts inputs up to VDD + 0.5 V and outputs rail-to-rail logic levels. Use Value: Avoids dedicated level shifters; single MC14584BCP handles six bidirectional signal paths with hysteresis-enhanced noise margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD40106BE | Same 14-pin SOIC package, but lower max VDD (15 V), higher typical propagation delay (150–300 ns), and reduced hysteresis (0.15–1.2 V). | Suitable for cost-sensitive consumer designs where 15 V ceiling and relaxed timing are acceptable. | Select CD40106BE only if supply stays ≤15 V and timing budget allows >150 ns delay. |
| SN74LV14APWR | 3.3 V only (1.65–3.6 V), smaller TSSOP-14 package, faster propagation (5.5 ns typ), no high-voltage tolerance. | Optimized for modern low-voltage digital systems requiring high speed and small footprint. | Choose SN74LV14APWR when operating exclusively at 3.3 V and sub-10 ns timing is critical. |
Compared with CD40106BE and SN74LV14APWR, the MC14584BCP uniquely supports 18 V operation, delivers wider hysteresis for harsh-noise environments, and maintains full functionality across −55 °C to +125 °C - making it the only choice for high-reliability industrial and automotive signal conditioning where voltage headroom and thermal stability are non-negotiable.

FAQ
What is the maximum supply voltage rating for MC14584BCP?
The MC14584BCP has an absolute maximum DC supply voltage (VDD) of +18.0 V, with recommended operating range from 3.0 V to 18 V. Exceeding 18.0 V risks permanent damage, and operation below 3.0 V may result in undefined output states or increased propagation delay. The MC14584BCP is rated for continuous operation across this full range at temperatures from −55 °C to +125 °C.
Does MC14584BCP support direct replacement of MC14069UB?
Yes, the MC14584BCP is explicitly specified as a drop-in replacement for the MC14069UB hex inverter when enhanced noise immunity is required. Both share identical pinout and supply compatibility, but the MC14584BCP adds Schmitt-trigger hysteresis - enabling reliable operation with slow-rising inputs where the MC14069UB would oscillate or produce ambiguous logic levels.
What is the hysteresis voltage (VH) of MC14584BCP at 5 V supply?
At VDD = 5.0 V, the MC14584BCP exhibits a hysteresis voltage (VH) of 0.25 V (min), 1.0 V (typ), and 1.0 V (max) across temperature - calculated as VT+ − VT−. This value increases with supply voltage, reaching up to 1.5 V at 15 V, providing scalable noise margin for varying signal amplitudes.
Can unused inputs on MC14584BCP be left floating?
No - unused inputs on the MC14584BCP must be tied to either VSS or VDD to prevent floating states that cause excessive current draw, erratic output behavior, or localized heating. The datasheet explicitly prohibits leaving inputs unconnected, as the high-impedance CMOS inputs are susceptible to noise-induced switching and potential latch-up.
Is MC14584BCP RoHS compliant and Pb-free?
Yes, the MC14584BCP is Pb-free and RoHS compliant, as confirmed by onsemi's official documentation and marking diagram (suffix "G" denotes Pb-free packaging). It meets EU Directive 2011/65/EU and is compatible with standard lead-free reflow soldering profiles, including peak temperatures up to 260 °C for 8 seconds.
