These devices are 16-bit D-type registers designed for use as buffered registers in high-speed, low power bus applications. These devices can be used as two independent 8-bit registers or as a single 16-bit register by connecting the output Enable (OE) and Clock (CLK) inputs. The outputs are 24-mA balanced output drivers with current limiting resistors to reduce the need for external terminating resistors, and provide for minimal undershoot and reduced ground bounce. Flow-through pinout and small shrink packaging aid in simplifying board layout. The CY74FCT163H374 has "bus hold" on the data inputs, which retains the input's last state whenever the source driving the input goes to high impedance. This eliminates the need for pull-up/down resistors and prevents floating inputs. The CY74FCT163374 is designed with inputs and outputs capable of being driven by 5.0V buses, allowing its use in mixed voltage systems as a translator. The outputs are also designed with a power off disable feature enabling its use in applications requiring live insertion.
