DS1644LPM
NOTES:
1. All voltages are referenced to ground.
OUTPUT LOAD
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. tAH1, tDH1 are measured from WE going high.
D.U.T.
1KΩ
6. tAH2, tDH2 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.
