NOTES (READ CYCLE)

1. t

HZ

and t

OHZ

are defined as the outputs achieve the open circuit conditions and are not referanced to output voltage levels.

2. At any given temperature and voltage condition, t

HZ

(Max.) is less than t

LZ

(Min.) both for a given device and from device to device

interconnection.
