RECOMMENDED OPERATING CONDITIONS FOR 74HCU

RATINGS

Limiting values in accordance with the Absolute Maximum System (IEC 134)

Voltages are referenced to GND (ground = 0 V)

Note

1. For analog switches, e.g. “4016”, “4051 series”, “4351 series”, “4066” and “4067”, the specified maximum operating

supply voltage is 11 V.
