Pericom Semiconductor’s PI74LPT16374 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 PI74LPT16374 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.

Delays and Enable/Disable times should be degraded by 20%.
2. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
3. Minimum limits are guaranteed but not tested on Propagation Delays.
4. This parameter is guaranteed but not production tested.
5. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
