U74LVC2G14
CMOS IC
DUAL SCHMITT-TRIGGER
INVERTER WITH 5V
TOLERANT INPUT
„
DESCRIPTION
The UTC U74LVC2G14 is a high-performance, low-power,
low-voltage, Si-gate CMOS device which provides two inverters with
Schmitt trigger action. It is capable of transforming slowly changed
input signals into sharply defined, jitter-free output signals.
„
FEATURES
* Operate From 1.65V to 5.5V
* 5V tolerant input/output for interfacing with 5V logic
*±24mA output drive (VCC =3.3V)
* CMOS low-power consumption and high noise immunity
* Halogen Free
