WARNINGS:
Under no circumstances are negative undershoots, of any amplitude, allowed when device is in battery backup mode.
Water washing for flux removal will discharge internal lithium source because exposed voltage pins
are present.
NOTES:
1. All voltages are referenced to ground.
2. Measured with a load as shown in Figure 1.
3. Pin locations are designated “U” (for upper) when a parameter definition refers to the socket receptacle and “L”
(for lower) when a parameter definition refers to the socket pin.
4. No memory inserted in the socket.
5. Pin 26 L may be connected to V
