Logic inputs. INx operate properly on TTL or CMOS levels. Output valid from VI = VCC– + 2 V to 15 V. Connect to 5 V

when not used.

ON/OFF

4

ON/OFF shuts down the entire circuit. It cannot be left open. For normally on operation, connect between 5 V and 10 V.

If VIL is at or near 0.8 V, significant settling time may be required.
