The device operates over a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs that accept voltages up to 5.5 V, enabling use as a translator in mixed 3.3V and 5V environments. The Schmitt-trigger action at all inputs provides unlimited input rise and fall time tolerance, making the circuit highly suitable for noisy signal environments. The device offers \u00b124 mA output drive capability and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C\/JESD36. ESD protection exceeds 2000V HBM and 1000V CDM. The device is specified from -40\u00b0C to +125\u00b0C.","working_principle":"The 74LVC14APW contains six independent inverting Schmitt-trigger gates. Each gate performs the Boolean function Y = NOT A, with Schmitt-trigger input action providing hysteresis between positive-going (VT+) and negative-going (VT-) threshold voltages. This hysteresis eliminates output oscillation and jitter caused by noisy or slowly transitioning input signals. When the input exceeds VT+, the output transitions LOW; when the input falls below VT-, the output returns HIGH. The 5V tolerant inputs allow direct interfacing with 5V logic devices while operating from a 3.3V supply, functioning as a level translator. The CMOS output stage provides \u00b124 mA drive capability with low static power consumption.","pin_description":"\n
