Like the ones that I mentioned, these obtain their low Iq by sampling the
inputs.
Nominal sampling interval is 50 mS but can be 100 mS worst case.

Outputs are true bipolar so as Allan says, ORing is needed.
Diodes 'should work' OK.

Package is either tiny or very tiny.
HVS0F5 1.6mm x 1.2mm is leaded.
VCSC50L1 is 1.1mm x 1.1mm mit bumps.
