Note 1

Absolute Maximum Ratings are those values beyond which damage to the device may occur

Note 2

Unless otherwise specified all voltages are referenced to ground

Note 4

For a power supply of 5V g10% the worst case output voltages (VOH and VOL) occur for HC at 45V Thus the 45V values should be used when designing

with this supply Worst case VIH and VIL occur at VCCe55V and 45V respectively (The VIH value at 55V is 385V) The worst case leakage current (IIN ICC and

IOZ) occur for CMOS at the higher voltage and so the 60V values should be used

VIL limits are currently tested at 20% of VCC The above VIL specification (30% of VCC) will be implemented no later than Q1 CY’89
