Product details

Overview

HCF4093M013TR from STMicroelectronics is a quad 2-input NAND Schmitt trigger IC in SO14 package, operating from 3 V to 20 V supply, with hysteresis voltage of 0.9 V (typ.) at 5 V, input leakage ≤100 nA at 18 V, and propagation delay of 190 ns (typ.) at 5 V. It enables robust signal conditioning in noisy industrial control interfaces.

For engineers reviewing the HCF4093M013TR datasheet, HCF4093M013TR pinout, HCF4093M013TR application, or HCF4093M013TR equivalent, key selection criteria include supply voltage range (3–20 V), Schmitt trigger hysteresis (0.9–5.0 V), output drive capability (±1.36 mA at 5 V), and extended temperature operation (–55 °C to +125 °C).

Technical Context

The HCF4093 implements four independent 2-input NAND gates, each with dual Schmitt-trigger inputs-ensuring distinct positive (VP) and negative (VN) switching thresholds and defined hysteresis (VH = VP – VN). This architecture rejects noise without external RC components.

Each gate operates with symmetrical output characteristics, supports unlimited input edge rates, and maintains stable quiescent current (≤30 µA at 5 V, ≤600 µA at 20 V) across its full –55 °C to +125 °C operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 20 V - supports wide-battery and industrial rail designs without level-shifting.
Hysteresis Voltage (VH)	0.9 V (typ.) at VDD = 5 V - provides ≥50 % noise immunity relative to VDD for reliable edge detection.
Propagation Delay	190 ns (typ.) at VDD = 5 V, CL = 50 pF - enables reliable timing in sub-MHz digital interface conditioning.
Input Leakage Current	≤100 nA at VDD = 18 V, TA = 25 °C - ensures minimal loading on high-impedance sensor or oscillator outputs.
Output Drive (IOH/IOL)	±1.36 mA (sink/source) at VDD = 5 V - sufficient to directly drive TTL loads or small logic fanouts.
Operating Temperature	–55 °C to +125 °C - qualified for under-hood automotive and harsh industrial environments.

Pinout & Package

Package: SO14 (Small Outline, 14-pin, 3.9 mm body width, 1.27 mm pitch), RoHS-compliant ECOPACK® variant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 8, 9, 12, 13	Data Inputs (A–H)	Eight Schmitt-trigger inputs grouped as four NAND pairs (e.g., pins 1&2 → output 3); tolerate slow/noisy edges.
3, 4, 10, 11	Data Outputs (J–M)	Four buffered NAND outputs with symmetrical VOH/VOL and ±1.36 mA drive at 5 V.
7	VSS	Negative supply terminal - must be connected to system ground; defines logic low reference.
14	VDD	Positive supply terminal - accepts 3–20 V DC; powers all four gates and sets threshold voltages.

Key Features

Feature	Design Value
Schmitt trigger action per input	Eliminates need for external hysteresis components; enables clean switching from slow-rising signals like thermistor dividers or mechanical switch bounce.
Hysteresis voltage programmable via VDD	VH scales with supply: 0.9 V (5 V), 2.3 V (10 V), 5.0 V (15 V) - simplifies design across multiple rail systems.
No input rise/fall time limit	Accepts arbitrarily slow transitions (e.g., from RC timing networks or analog comparators) without metastability or oscillation.
100% tested quiescent current	Guarantees low standby power (≤30 µA at 5 V) - critical for battery-backed or always-on monitoring circuits.

Applications

Industrial Sensor Interface

Automotive Body Control

Use Scenario: Debouncing mechanical door latch switches in vehicle body modules under EMI-rich environments.

IC Role / Device Role / Timing Role: Schmitt-trigger NAND gate converts noisy, slow-switching contacts into clean, jitter-free logic edges for microcontroller GPIO input.

Use Value: Eliminates software debouncing overhead and prevents false wake-ups; operates reliably at –40 °C to +125 °C ambient.

Use Scenario: Converting analog HVAC potentiometer wiper signals into stable digital thresholds for climate control MCU.

IC Role / Device Role / Timing Role: Input hysteresis rejects ripple and noise on resistive divider outputs before ADC sampling or comparator triggering.

Use Value: Reduces firmware filtering complexity; VH = 2.3 V at 10 V rail ensures ≥2 V noise margin against conducted transients.

Computer Power Sequencing

Consumer Appliance Timing

Use Scenario: Generating delayed enable signals for multi-rail CPU core and I/O power supplies using RC-Schmitt oscillator topology.

IC Role / Device Role / Timing Role: Configured as astable multivibrator; hysteresis defines precise frequency setpoint independent of supply drift.

Use Value: Enables accurate, supply-tolerant timing (tPLH = 190 ns typ.) without crystal or capacitor tolerance dependency.

Use Scenario: Synchronizing washing machine motor phase sequencing with zero-crossing detection from triac driver feedback.

IC Role / Device Role / Timing Role: Cleans up noisy AC-derived zero-cross pulses before feeding to MCU timer capture input.

Use Value: Prevents missed or double-counted zero-cross events; input leakage ≤100 nA avoids loading sensitive optocoupler outputs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4093BE	PDIP-14 package only; wider propagation delay (250 ns typ. at 5 V); no AEC-Q100 qualification.	Limited to lab/prototype use; unsuitable for automotive or high-reliability industrial PCBs requiring surface-mount assembly.	Select when through-hole prototyping or legacy DIP footprint compatibility is required.
SN74LVC1G57DBVR	Single-gate, 3.3 V only (1.65–5.5 V); CMOS logic family; no inherent hysteresis - requires external feedback resistor.	Requires external 100 kΩ resistor to implement Schmitt behavior; not drop-in compatible for quad-function or wide-VDD designs.	Choose only for space-constrained, low-voltage (≤3.6 V) applications where single-gate flexibility outweighs hysteresis integration.

Compared with CD4093BE and SN74LVC1G57DBVR, the HCF4093M013TR delivers integrated quad Schmitt NAND functionality in a qualified SO14 package with 3–20 V operation, eliminating external components and enabling direct replacement in legacy 4000-series designs while meeting automotive-grade reliability requirements.

FAQ

What is the maximum supply voltage rating for HCF4093M013TR?

The absolute maximum supply voltage (VDD) is +22 V, but recommended operating range is 3 V to 20 V. Operation above 20 V risks exceeding specified electrical characteristics and reduces long-term reliability, especially at elevated temperatures. The device is fully characterized up to 20 V with guaranteed quiescent current and propagation delay performance.

Can HCF4093M013TR drive LED indicators directly?

Yes - each output can sink or source up to ±1.36 mA at 5 V, sufficient to drive low-current indicator LEDs (e.g., 2 mA @ 1.8 V forward voltage) with a series resistor ≥1.6 kΩ. At 15 V supply, output sink current reaches 2.4 mA, supporting higher-brightness LEDs with appropriate current limiting.

Is HCF4093M013TR pin-compatible with older CD4093 variants?

Yes - it shares identical SO14 pinout and logic function with CD4093B variants. However, HCF4093M013TR offers tighter hysteresis control, lower input leakage (≤100 nA vs. ≤500 nA), and extended temperature qualification (–55 °C to +125 °C), making it a functional and reliability upgrade for existing designs.

Does HCF4093M013TR require external pull-up or pull-down resistors on unused inputs?

No - unused inputs should be tied to VDD or VSS to prevent floating nodes, but no external resistors are needed due to the Schmitt-trigger input structure. Leaving inputs unconnected risks increased supply current and erratic output behavior; direct connection ensures deterministic logic state and minimizes noise susceptibility.
