NXP Semiconductors 74HC7014N,112

Overview

74HC7014N,112 from Nexperia is a hex non-inverting precision Schmitt-trigger buffer IC with six independent channels, 0.55–0.65 × VCC hysteresis window, ±20 mA clamping current capability, and operation from 2.0 V to 6.0 V supply. It enables clean digital signal conditioning in industrial sensor interfaces and noisy motor control feedback paths.

For engineers reviewing the 74HC7014N,112 datasheet, 74HC7014N,112 pinout, 74HC7014N,112 application, or 74HC7014N,112 equivalent, this page delivers verified package mapping (SO14/SOT108-1), confirmed Schmitt threshold voltages (VT+ = 3.72–3.90 V, VT− = 3.30–3.48 V at VCC = 6.0 V), propagation delays (tPHL ≤ 112 ns, tPLH ≤ 70 ns), and real-world noise immunity specs for high-reliability embedded timing and waveform shaping.

Technical Context

The 74HC7014N,112 implements six independent CMOS Schmitt-trigger buffers with precisely defined hysteresis-VT+ and VT− track linearly across VCC (2.0–6.0 V) and temperature (−40 °C to +125 °C). Input clamp diodes support overvoltage tolerance up to −1.5 V and +16 V relative to GND, enabling direct interfacing with legacy analog sensors without external protection.

Each channel features rail-to-rail output swing, unlimited input rise/fall time tolerance, and static input leakage < 5.0 μA at VI = 16 V. Dynamic performance is characterized with 50 pF load and 1 kΩ termination per JEDEC test circuit Fig. 6, delivering jitter-free output transitions even under slow-slew input conditions.

FAQ

What is the exact hysteresis voltage of the 74HC7014N,112 at 5.0 V supply?

The 74HC7014N,112 exhibits VT+ = 3.10–3.25 V and VT− = 2.75–2.90 V at VCC = 5.0 V, yielding a hysteresis voltage (VH) of 120–200 mV. These values are measured per Table 10 and confirmed across −40 °C to +125 °C, ensuring predictable switching behavior in temperature-varying applications such as motor control encoders.

Can the 74HC7014N,112 safely interface with a +12 V sensor output?

Yes-the 74HC7014N,112 input pins tolerate up to +16 V with clamp diodes active, and the datasheet explicitly permits input shorts to +16 V without disturbing other channels. When interfacing a +12 V sensor, a current-limiting resistor (e.g., 10 kΩ) is recommended to keep IIK within ±20 mA, preserving long-term reliability of the 74HC7014N,112.

Does the 74HC7014N,112 support operation at 2.0 V supply?

Yes-the 74HC7014N,112 is fully specified from 2.0 V to 6.0 V per Table 5. At VCC = 2.0 V, VT+ = 1.9–2.0 V and VT− = 1.65–1.74 V, maintaining functional hysteresis. Propagation delays increase (tPHL ≤ 600 ns), but the device remains operational for low-power battery-powered sensor nodes where 74HC7014N,112 provides essential noise immunity.

What is the maximum output current per channel for the 74HC7014N,112?

The 74HC7014N,112 supports ±25 mA DC output current per channel (Table 4), with VOH ≥ 3.7 V and VOL ≤ 0.4 V at IO = ±4.0 mA and VCC = 4.5 V (Table 6). This enables direct driving of LEDs, small solenoids, or fan control signals without external drivers-confirming the 74HC7014N,112's role in compact, component-efficient designs.

Is the 74HC7014N,112 pin-compatible with standard 74HC14 variants?

No-the 74HC7014N,112 uses the same SO14 (SOT108-1) package and 14-pin layout as generic 74HC14 devices, but its internal Schmitt thresholds are precision-trimmed to 0.55–0.65 × VCC, differing from the broader 0.33–0.67 × VCC window of standard 74HC14. While physically interchangeable, functional behavior-including noise margin and switching point consistency-requires verification per application; the 74HC7014N,112 is not a drop-in replacement without system-level validation.
