+SN74LVC2G14 — Dual Schmitt-Trigger Inverter
6
+
7
+The SN74LVC2G14 contains two independent Schmitt-trigger inverters and implements the Boolean function Y =
8
+¬A (inverter). Key features and corrected description:
9
+
10
+- Supply voltage: 1.65 V to 5.5 V (VCC)
11
+- Package: NanoFree™ package technology (die as the package)
12
+- Function: Two inverters with Schmitt-trigger inputs (separate thresholds for rising and falling edges)
13
+ - Positive-going threshold: Vt+
14
+ - Negative-going threshold: Vt-
15
+- Special feature: The Schmitt action provides hysteresis, improving noise immunity and signal clean-up on slow or noisy inputs.
16
+- Power-down behavior: The device is specified for partial-power-down applications using Ioff outputs. The Ioff circuitry prevents damaging current backflow through the device when it is powered down while other parts of the system remain powered.
17
+
18
+Notes:
19
+- Use this device when you need level translation, input hysteresis, or signal conditioning across a wide VCC range.
