Nexperia USA Inc. 74LV14D,112

Overview

74LV14D,112 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with six independent channels, designed for noise-immune signal conditioning in industrial and embedded systems. It operates from 1.0 V to 5.5 V, delivers input hysteresis (VH) up to 1.5 V at 5.5 V supply, supports TTL-level inputs at 2.7–3.6 V, and is rated for -40 °C to +125 °C operation in SO14 (SOT108-1) package.

For engineers reviewing the 74LV14D,112 datasheet, 74LV14D,112 pinout, 74LV14D,112 application, or 74LV14D,112 equivalent, key selection criteria include supply voltage flexibility (1.0–5.5 V), guaranteed Schmitt-trigger hysteresis across temperature, propagation delay of 13 ns typical at 3.3 V/15 pF, and compatibility with legacy 74HC14/74HCT14 designs in noise-prone timing and waveform-shaping circuits.

Technical Context

The 74LV14D implements six independent inverting Schmitt-trigger buffers using Si-gate CMOS technology. Each channel features asymmetric switching thresholds (VT+ and VT−) to provide hysteresis, enabling clean digital output from slow or noisy analog inputs. The device uses standard CMOS logic levels but accepts TTL-compatible inputs when VCC is between 2.7 V and 3.6 V.

Its functional behavior is defined by transfer characteristics where VT+ ranges from 0.70 V (at VCC = 1.2 V) to 3.85 V (at VCC = 5.5 V), and VT− ranges from 0.34 V to 2.6 V under same conditions - yielding VH = VT+ − VT− up to 1.5 V. Propagation delay varies from 80 ns at 1.2 V to 18 ns at 5.5 V, with typical 13 ns at 3.3 V/15 pF load.

FAQ

What is the maximum recommended operating frequency for 74LV14D,112?

The 74LV14D,112 does not specify a maximum clock frequency, as it is not a synchronous device. Its usable edge rate is governed by propagation delay: 13 ns typical at 3.3 V/15 pF yields effective signal conditioning up to ~30 MHz. For oscillator use, frequency depends on external R/C values and is limited by tpd and output drive strength into the load capacitance.

Can 74LV14D,112 drive a 50 pF load reliably at 3.3 V?

Yes. At VCC = 3.3 V, the 74LV14D,112 maintains VOL ≤ 0.40 V and VOH ≥ 2.82 V with 6 mA sink/source load, and dynamic characteristics confirm stable operation with CL = 50 pF (CPD = 15 pF measured). Output rise/fall times remain under 10 ns, ensuring clean transitions even at full capacitive load.

Is the SO14 package of 74LV14D,112 RoHS compliant and lead-free?

Yes. The 74LV14D,112 in SOT108-1 (SO14) package is manufactured per Nexperia's standard RoHS-compliant, lead-free process. Its marking "112" denotes a lead-free, halogen-free variant conforming to EU Directive 2011/65/EU and JEDEC JS-001/JS-002 ESD standards.

How does the input hysteresis of 74LV14D,112 improve noise immunity compared to standard inverters?

Unlike standard inverters with single threshold, the 74LV14D,112 uses separate VT+ (e.g., 1.60 V) and VT− (e.g., 1.05 V) thresholds at 3.0 V supply, creating 550 mV hysteresis. This prevents multiple toggles when input voltage lingers near threshold due to noise - requiring noise amplitude >550 mV to cause unintended switching, significantly exceeding typical PCB-coupled interference levels.
