Batch #3, all pins has NO solder on it, NOS ? Date code 9609, manufactured in Malaysia. Cost USD $1.53

Did some measurement with the supply current (Vs +- 15V)
with both input 1k ohm to ground:
IS+EN 4.98 ma (data sheet typical 8.4 max 12)
IS+DIS 2.27 ma (data sheet typical 4.7 max 6)
IS-EN 9.54 ma (data sheet typical 13.0 max 17)
IS-DIS 3.23 ma (data sheet typical 5.0 max 6.5)

If so, wonder what is inside as it response to the voltage level change on CS.
