18.2.2 Naming Conventions for Latches

The names for the latch cells are composed of the following four parts:

• A name identifying the logic function as a latch (LD)
• An optional 1-character code describing the Enable pin. L indicates active low. No code indicates active high

Storage Cells

• Asynchronous input type; an optional 1-character code designating the control pins as follows:
  • B = Active high, both set and clear
  • C = Active high clear
  • S = Active high set

  When the latch has neither SET nor CLEAR pins, this code is omitted.

• An optional 1-character code describing the output polarity. I indicates output is inverted. No code indicates output is not inverted.
