Overview
UNISONIC TECHNOLOGIES CO.
, LTD U74LVC244 OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS CMOS IC  DESCRIPTION The UTC U74LVC244 contains two 4-bit line drivers with separate output-enable ( OE ) inputs.
When OE is low, the device passes data from the A to the Y.
When OE is high, the outputs are in the high-impedance state.
The UTC U74LVC244 can be used in a mixed 3.
3V/5V system environment.
 FEATURES * Operate From 1.
65V to 3.
6V * Input Accept Voltages to 5.
5V * Partial-Power-Down Mode Operation * Max tpd is 5.
9ns at 3.
