DS1644LPM
041697 10/11
NOTES:
1. All voltages are referenced to ground.
2. Typical values are at 25
°
C and nominal supplies.
3. Outputs are open.
4. Data retention time is at 25
°
C and is calculated from
the date code on the device package. The date code
XXYY is the year followed by the week of the year
in which the device was manufactured. For exam-
ple, 9225, would mean the 25th week of 1992.
5. t
AH1
, t
DH1
are measured from WE going high.
6. t
AH2
, t
DH2
are measured from CE going high.
7. Unencapsulatesd Low Profile Modules are not rec-
ommended for processing through conventional
wavesoldering techniques. The Use of a PLCC
socket is recommended for production purposes.
