UNISONIC TECHNOLOGIES CO., LTD U74LVC1G17
SINGLE SCHMITT-TRIGGER BUFFER
DESCRIPTION
The UTC U74LVC1G17 is a single Schmitt-trigger buffer, it provides the function Y=A.
The device have different input threshold levels for positivegoing (VT+) and negative-going(VT-) signals because of the Schmitt-trigger action in the input.
This device has power-down protective circuit, preventing device destruction when it is powered down.
FEATURES
* Operation Voltage Range: 1.6V ~ 5.5V * Low Power Current: ICC=10μA (Max.) * ±24mA Output Drive (VCC=3.0V) * Power Down Protection

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
