AC Programming Characteristics

A = 25 ± 5°C, VCC = 6.5 ± 0.25V, OE/VPP = 13.0 ± 0.25V

Notes:

1. V

CC must be applied simultaneously or before OE/VPP and removed simultaneously or after OE/VPP.

2. This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven—

see timing diagram.

3. Program Pulse width tolerance is 50

µs ± 5%.
