Vpp may be connected directly to Vcc except during programming.The supply current would then be the sum of ICC and IpP1 '3. Typical values are for T amb = 25°C and nominal supply voltages.4. This parameter is only sampled and not 100% tested. Output Float is defined as the point where data is no longer driven.(See timing diagram).5. This parameter is only sampled and is not 100"Al tested.3/1055
