Fast CMOS 3.3V
16-Bit Register (3-State)
ProductFeatures
Product Description
• FunctionallycompatiblewithFCT3,LVT,
and 74 series 16374 families of products
The PI74LCX16374 is a 16-bit octal register designed with 16
D-typeflip-flopswithabufferedcommonclockand3-stateoutputs.
TheOutputEnable(xOE)andclock(xCLK) controlsareorganized
to operate as two 8-bit registers or one 16-bit register. When OE is
HIGH, the outputs are in the high impedance state. Input data
meeting the setup and hold time requirements of the D inputs is
transferred to the O outputs on the LOW-to-HIGH transition of the
clock input.
• 3-state outputs
• 5V Tolerant inputs and outputs
• 2.0V-3.6VVCC supplyoperation
• Balanced sink and source output drives (24mA)
• Low ground bounce outputs
ThePI74LCX16374canbedrivenfromeither3.3Vor5.0Vdevices
allowing this device to be used as a translator in a mixed
3.3/5.0V system.
