VIRGIN STATE

The factory shipped virgin device contains all

fusible links intact, such that:

1. OE is always enabled.

2. Preset and Reset are always disabled.

3. All transition terms are disabled.

4. All flip-flops are in D-mode unless

otherwise programmed to J-K only or J-K

or D (controlled).

5. All B pins are inputs and all F pins are

outputs unless otherwise programmed.

CAUTION: PLS159A

PROGRAMMING ALGORITHM

The programming voltage required to

program the PLS159A is higher (17.5V) than

that required to program the PLS159 (14.5V).

Consequently, the PLS159 programming

algorithm will not program the PLS159A.

Please exercise caution when accessing

programmer device codes to insure that the

correct algorithm is used.
