DATA SHEET REVISION SUMMARY
The following represent the key differences between 12/16/96 and 06/12/97 version of the DS1314 data
sheet. Please review this summary carefully.
1. Changed V
BAT
max to 6V.
2. Changed V
CCTP
values to 2.8 - 3.0V (TOL = GND) and 2.5 - 2.7V (TOL = V
CC
).
3. Changed t
BABW
from 7s to 1s max.
4. Changed block diagram to show U L compliance.
The following represent the key differences between 06/12/97 and 08/29/97 version of the DS1314 data
sheet. Please review this summary carefully.
1. Changed AC test conditions.
2. Changed t
PD
to 20 max & 12 typ.
The following represent the key differences between 08/29/97 and 12/16/97 version of the DS1314 data
sheet. Please review this summary carefully.
1. Changed V
CCI
mins from 3.05V to 3.0V (TOL=GND) and from 275V to 2.7V (TOL=V
CCD
) (this
should have been done on 06/12/97 revision but was overlooked).
2. Specified Input Capacitance as being only for
CEI
, TOL and Output Capacitance as being only for
CEO
,
BW
and
RST
. This is not a change but rather clarification.
3. Removed “preliminary” from title bar.
The following represent the key differences between 12/16/97 and 6/12 version of the DS1314 data sheet.
