Fast CMOS 3.3V 16-Bit Register (3-State)

Product Description

The PI74LCX16374 is a 16-bit octal register designed with 16

D-type flip-flops with a buffered common clock and 3-state outputs.

The Output Enable (xOE) and clock (xCLK) controls are organized

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.

The PI74LCX16374 can be driven from either 3.3V or 5.0V

devices allowing this device to be used as a translator in a mixed

3.3/5.0V system.
