Product details

Overview

HEF4093BT/S400,118 from NXP Semiconductors is a quad 2-input NAND Schmitt-trigger IC in SO-14 package, operating from 3V to 15V supply, with typical propagation delay of 80 ns at 5V and hysteresis voltage of 1.5 V (V_DD = 5 V). It functions as a noise-immune digital logic gate for signal conditioning in clock generation and debouncing circuits.

For engineers reviewing the HEF4093BT/S400,118 datasheet, HEF4093BT/S400,118 pinout, HEF4093BT/S400,118 application, or HEF4093BT/S400,118 equivalent, key selection criteria include supply voltage range, input hysteresis, propagation delay consistency across V_DD, and SO-14 thermal performance in high-noise industrial control environments.

Technical Context

The HEF4093BT/S400,118 implements four independent NAND gates, each with Schmitt-trigger inputs to reject analog noise on digital signals. Its hysteresis threshold is internally fixed at ≈1.5 V (V_DD = 5 V) and scales linearly with supply voltage up to 15 V.

Each gate drives TTL- and CMOS-compatible loads with output low current of 3.2 mA (V_DD = 5 V) and output high current of –1.5 mA. Input leakage remains below ±100 nA over –40°C to +125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 15 V - supports direct interface with legacy 5 V and modern 3.3 V/12 V systems without level shifters.
Input Hysteresis (ΔV_IN)	1.5 V at V_DD = 5 V - ensures reliable switching in presence of >100 mV peak-to-peak noise on push-button or sensor inputs.
Propagation Delay (t_PHL/t_PLH)	80 ns max at V_DD = 5 V - enables stable 10 MHz clock shaping in oscillator configurations.
Output Drive (I_OL/I_OH)	3.2 mA / –1.5 mA at V_DD = 5 V - directly drives LEDs, small relays, or next-stage CMOS inputs without external buffers.
Operating Temperature	–40°C to +125°C - qualified for under-hood automotive and industrial motor control applications.
Quiescent Current (I_DD)	20 μA max at V_DD = 5 V - enables low-power wake-up detection in battery-backed systems.

Pinout & Package

HEF4093BT/S400,118 is housed in a 14-pin Small Outline (SO-14) package with standard JEDEC MS-012AC footprint, 1.27 mm pitch, and 1.75 mm body height - compatible with automated SMT assembly and IPC-7351B land patterns.

Pin/Terminal	Circuit Role	Design Meaning
1, 5, 9, 13	NAND Gate Input A	Schmitt-trigger input with hysteresis; accepts slow-rising or noisy signals without oscillation.
2, 6, 10, 12	NAND Gate Input B	Second Schmitt-trigger input per gate; both inputs must be high for low output.
3, 4, 8, 11	NAND Gate Output	CMOS-compatible push-pull output; sinks 3.2 mA or sources 1.5 mA at 5 V.
7	GND	Ground reference for all logic thresholds and output drivers; requires low-impedance connection.
14	V_DD	Positive supply rail; decoupling capacitor (100 nF) required within 5 mm of this pin.

Key Features

Feature	Design Value
Quad independent Schmitt-trigger NAND gates	Enables four separate noise-immune logic functions in one SO-14 footprint - reduces board area vs discrete RC+inverter solutions.
Wide supply range (3–15 V)	Eliminates need for separate voltage regulators when interfacing mixed-voltage subsystems (e.g., 3.3 V MCU with 12 V sensor).
Guaranteed hysteresis over full temperature range	Maintains ≥1.2 V hysteresis from –40°C to +125°C - ensures consistent switch-point stability in thermal cycling environments.
Low input leakage (±100 nA max)	Preserves RC time constants in precision timing circuits; avoids drift in monostable or astable oscillator designs.

Applications

Push-Button Debouncing

Oscillator Circuit

Use Scenario: Mechanical switch closure in industrial HMI panels generates 5–20 ms contact bounce.

IC Role / Device Role / Timing Role: Schmitt-trigger NAND gate configured as RS latch filters bounce and delivers clean single-edge output.

Use Value: Eliminates need for external RC networks or firmware debounce routines; reduces BOM count by two passive components per button.

Use Scenario: Generating stable square-wave clocks for microcontroller peripherals or LED flash timing.

IC Role / Device Role / Timing Role: Two gates form a relaxation oscillator with external R-C network; remaining gates buffer or divide frequency.

Use Value: Achieves <±2% frequency stability over temperature without crystal; supports 10 kHz–1 MHz range with single resistor tuning.

Signal Conditioning

Power-On Reset Generation

Use Scenario: Analog sensor outputs (e.g., thermistor divider) exhibit slow ramping and EMI-induced jitter.

IC Role / Device Role / Timing Role: Single NAND gate acts as level detector with hysteresis to convert analog ramp into clean digital transition.

Use Value: Prevents false triggering in comparator-based monitoring; sets precise 1.5 V threshold without trimming potentiometers.

Use Scenario: Ensuring microcontroller reset pulse exceeds minimum duration (e.g., 100 ms) after power rail stabilization.

IC Role / Device Role / Timing Role: RC network charges into Schmitt-trigger input; NAND gate inverts and extends pulse width via feedback.

Use Value: Generates monotonic, glitch-free reset signal independent of supply ramp rate; eliminates reliance on dedicated reset ICs.

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 variation (60–120 ns); no AEC-Q100 qualification.	Limited to lab prototypes or non-automotive PCBs; unsuitable for reflow-soldered production or under-hood use.	Select CD4093BE only for breadboard validation where SO-14 footprint or automotive temp grade is not required.
74HC14D	Hex inverter (not NAND); lower hysteresis (≈0.8 V at 5 V); 2 V–6 V supply range only.	Requires additional logic gates for NAND functionality; insufficient noise margin for 12 V sensor interfaces.	Choose 74HC14D only when inverting-only function suffices and supply is strictly ≤6 V.

Compared with CD4093BE and 74HC14D, the HEF4093BT/S400,118 uniquely combines quad NAND topology, 3–15 V operation, and AEC-Q100-qualified SO-14 packaging - enabling single-component solutions for automotive reset, industrial debounce, and multi-rail timing where voltage flexibility and noise immunity are co-critical.

FAQ

What is the maximum recommended supply voltage for HEF4093BT/S400,118?

The absolute maximum supply voltage is 18 V, but the device is fully specified and characterized from 3 V to 15 V. Operation above 15 V voids parametric guarantees including propagation delay, hysteresis, and output drive strength - sustained use beyond 15 V risks accelerated oxide degradation and reduced long-term reliability.

Can HEF4093BT/S400,118 drive a 5 V relay coil directly?

Yes - at V_DD = 5 V, the output sink current capability is 3.2 mA minimum, sufficient to activate low-power 5 V relays with coil resistance ≥1.5 kΩ. For higher-current relays (>5 mA), an external NPN transistor or MOSFET driver is required to avoid exceeding I_OL limits and causing output voltage droop.

Is HEF4093BT/S400,118 pin-compatible with CD4093B?

Yes - both devices share identical SO-14 pinout and logic function mapping. However, HEF4093BT/S400,118 offers tighter propagation delay distribution, guaranteed hysteresis over temperature, and AEC-Q100 qualification, whereas CD4093B lacks automotive qualification and exhibits wider parameter spread across voltage and temperature.

Does HEF4093BT/S400,118 require external pull-up resistors on outputs?

No - it features true CMOS push-pull outputs with active high and active low drivers. Pull-ups are unnecessary unless interfacing with open-drain inputs or implementing wired-AND logic. Adding pull-ups increases static power consumption and may cause contention if output drives low while pull-up pulls high.
