General Description
The PEEL18LV8Z is a Programmable Electrically Erasable The differences between the PEEL18LV8Z and
Logic (PEEL) SPLD (Simple Programmable Logic Device) PEEL18CV8 include the addition of programmable clock
that operates over the supply voltage range of 2.7V-3.6V polarity, p-term clock, and Schmitt trigger input buffers on
and features ultra-low, automatic "zero" power-down all inputs, including the clock. Schmitt trigger inputs allow
operation. The PEEL18LV8Z is logically and functionally direct input of slow or noisy signals.
