The device is byte controlled. The flip-flops appear to be transparent to the data when the Latch enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the out- puts are in a high impedance state. The VCXH162373 data inputs include active bushold cir- cuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The VCXH162373 is also designed with 26 : series resis- tors in the outputs. This design reduces line noise in appli- cations such as memory address driver, clock drivers and bus transceivers/transmitters. The 74VCXH162373 is designed for low voltage (1.4V to 3.6V) VCC applications with output compatibility up to 3.6V. The 74VCXH162373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing low CMOS power dissipation.
