SINGLE BUS BUFFER GATE
WITH 3-STATE OUTPUT
DESCRIPTION
The UTC U74AHCT1G125 is a single bus buffer gate with 3-state
output controlled by enable input ( OE ), When OE is HIGH, the
output is disabled.
FEATURES
* Operation voltage range: 4.5V ~5.5V
* Low Power Current: ICC=1μA (Max.)
* ±8mA Output Drive at 5V
* Inputs are TTL-Voltage Compatible

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.
