Op Amp failure and prevention
You replaced a quad 741 type with a quad CMOS type which has rail-to-rail outputs.
CMOS is rugged in good design but can fail on the bench from a slip of usage.

This could be from driving a breadboard with a low impedance signal and controlling Vdd separately from the signal or from ESD exceeding the protection level.

The SCR latchup failure-effects may occur when either input exceeds the supply rail and delivers more than 5mA or the output is back-driven more than the current limit.

However, the output is current-limited and tolerates shorts to either rail.

a 100 ft cable with approx 20 pf/ft will represent 2nF load which is generally unstable on CMOS outputs unless you add a 50 to 100 Ohm series resistor.
