Links to three datasheets for 1488 chips:-
One thing I forgot to say in my earlier post. 1488 chips are based on old bipolar technology. This type runs warm even when doing nothing. If you look at the datasheets, the typical power consumption/ dissipation is around 576mW. That’s over half a watt of power in a normal DIL case.
