NOTES: 1. These parameters, although guaranteed over the
recommended operating conditions, are not tested in
production.
2. Parameter measured at trip point of latch with VPin 6 =
VREF, VPin 16 = 0V.
3. Amplifier gain is defined as:
4. Current into Pin 1 guaranteed to latch circuit in shutdown
state.
5. Current into Pin 1 guaranteed not to latch circuit in
shutdown state.
