NXP Semiconductors 74LVC14APW/C2118

Overview

74LVC14APW/C2118 from NXP Semiconductors is a hex inverting Schmitt trigger IC with 5 V tolerant inputs, operating from 1.2 V to 3.6 V supply, delivering 6 independent hysteresis-enabled inverters for noise-immune signal conditioning in mixed-voltage digital systems.

For engineers reviewing the 74LVC14APW/C2118 datasheet, 74LVC14APW/C2118 pinout, 74LVC14APW/C2118 application, or 74LVC14APW/C2118 equivalent, this device is selected for wave shaping, oscillator design, and level translation where input hysteresis, 5 V input compatibility, and low-power CMOS operation are required.

Technical Context

The 74LVC14APW/C2118 implements six independent Schmitt-trigger inverters, each with asymmetric positive-going (VT+) and negative-going (VT−) input thresholds to generate defined hysteresis (VH = VT+ − VT−), enabling clean output transitions from slow or noisy inputs. It supports dual-supply interoperability via 5 V tolerant inputs while powered from 1.2–3.6 V.

Its logic function strictly follows inverting behavior per channel (input A → inverted output Y), with static and dynamic performance characterized across −40 °C to +125 °C. Propagation delay ranges from 1.0 ns (VCC = 3.0–3.6 V) to 16 ns (VCC = 1.2 V), and output skew is guaranteed ≤1.5 ns across temperature.

FAQ

What is the maximum input voltage rating for 74LVC14APW/C2118?

The 74LVC14APW/C2118 supports input voltages up to 5.5 V, regardless of VCC level - a key feature enabling direct connection to 5 V logic sources without external protection. This 5 V tolerance is maintained across the full operating temperature range (−40 °C to +125 °C) and is validated per JEDEC JESD8-C standards. The 74LVC14APW/C2118 datasheet specifies VI(max) = +6.5 V as an absolute maximum limiting value, but recommended operation caps at 5.5 V for reliability.

Does 74LVC14APW/C2118 require external pull-up resistors on unused inputs?

No, the 74LVC14APW/C2118 does not include bus-hold circuitry, so unused inputs must be actively terminated - either tied to VCC or GND - to prevent floating states that could increase ICC or cause erratic output switching. Unlike the pin-compatible 74LVCH14PW, the 74LVC14APW/C2118 relies on external biasing for deterministic operation. This design choice minimizes quiescent current and simplifies thermal management in high-density layouts.

Can 74LVC14APW/C2118 operate at 1.2 V supply?

Yes, the 74LVC14APW/C2118 is fully specified down to 1.2 V supply voltage, with functional operation confirmed across −40 °C to +125 °C. At 1.2 V, propagation delay increases to 16 ns (typical), and output drive strength decreases, but logic thresholds scale proportionally to maintain noise margin. This capability makes the 74LVC14APW/C2118 suitable for ultra-low-power battery-operated devices where supply rails drop below 1.8 V during deep sleep modes.

What is the hysteresis voltage (VH) of 74LVC14APW/C2118 at 3.3 V supply?

At VCC = 3.3 V, the 74LVC14APW/C2118 exhibits a hysteresis voltage (VH) ranging from 0.3 V to 1.2 V, with typical VT+ ≈ 1.7 V and VT− ≈ 0.8 V. This 0.9 V nominal hysteresis provides strong immunity to noise spikes up to ±450 mV on the input line. The exact VH varies with temperature and process corner, but remains within the datasheet-specified bounds across the full −40 °C to +125 °C range, ensuring consistent wave-shaping performance.

Is 74LVC14APW/C2118 pin-compatible with other 74LVC14 variants?

Yes, the 74LVC14APW/C2118 shares identical pinout (14-pin TSSOP, SOT402-1) and logic function with all standard 74LVC14A package variants (e.g., SO14, SSOP14, DHVQFN14). All versions implement the same six inverting Schmitt triggers with identical terminal assignments: inputs on pins 1/3/5/9/11/13, outputs on 2/4/6/8/10/12, GND on 7, and VCC on 14. Mechanical differences exist only in package footprint and thermal characteristics - no PCB redesign is needed when migrating between packages.
