Notes: 1. A start-up delay of 200µs is required after power-up, followed by a minimum of eight initial ization cycles
(/RAS only r efresh or /CAS before /RAS ref r esh) before proper device operation is achiev ed.
2. The AC characteristic s assumes t
T
= 2ns.
3. V
IH
(Min.) and VIL(Max.) are ref erence lev els f or m easuring input tim ing signals. Transiti on ti me (tT) are
measured between V

and VIL.
4. This parameter is m easured wit h a load circuit equivalent to 2TTL loads and 100pF.
5. Operation within the t
RCD

RAC
(Max.) can be met.
t
RCD
(Max.) is specified as a reference point only. If t
RCD
is greater than the specified t
