74LV14A
Hex inverting Schmitt trigger
The 74LV14A is a hex inverter with Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Maximum tpd of 10 ns at 5 V
Typical VOL(p) < 0.8 V at VCC = 3.3 V, Tamb = 25 °C
Typical VOH(v) > 2.3 V at VCC = 3.3 V, Tamb = 25 °C
Supports mixed-mode voltage operation on all ports
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD 78 Class II
- ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 3000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 2000 V
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
