Drive Options for Internal Macrocells
This section describes types of macrocells that are typical macrocells, clock drivers.
Typical Macrocells
The complete set of internal macrocells available for our previous gate array series is usable in the TC200G/E designs. Like our previous series, the TC200G/E macrocells are available with two drive options: standard drive and power (double) drive. The form for internal macrocell type names is: Where: =denotes the generic function of a macrocell. =Null (i.e, no letter) for standard drive types; "P" for power-drive types. Example: ND2 ND2P
Standard-drive 2-input NAND gate Power-drive 2-input NAND gate
Use power drive types with heavy output load. However, be sure not to overuse power drive cells because they require a greater load drive capability of standard drive type cell.

Clock Driver
Four types of internal buffers are available to buffer heavily loaded internal signals IDRV4, IDRV8, IDRV16, and IDRV24. These buffers use largegeometry transistors in I/O slot regions to provide high fan-out on-chip drive capability. Use the appropriate one consistent with your needs.

Drive Options for I/O Macrocells
I/O buffer lines include input, output, and bidirectional types. The paragraphs that follow discuss drive options available for I/O buffers.
Input Buffer
* *
Standard type: High-speed type:
This type is effective in reducing noise. Use high-speed (or high-drive) input buffers to accommodate your critical path needs. High-speed options are available for part of the input buffers. Cell names have a suffix of "H".

Output Buffer
*
Standard type:
Standard drive types offer a drive capability that stands between comparable high-speed and slewrate-control types. Use high-speed(or high-drive)types to accommodate your critical path needs. High-speed options are available for output buffers with drive capability of no less than 4 mA. The cell name has a qualifier of "H" in it. Use output buffers with internal slew rate control circuit to minimize unwanted voltage transients. Slew rate control options are available for output buffers with drive capability of no less than 4 mA. The cell name has a qualifier of "R" in it.

Bidirectional Buffer
Bidirectional buffers contain various type which combine input buffers and output buffers described above.
