Philips Semiconductors Product specification
8-channel analog multiplexer/demultiplexer 74HC/HCT4051
DC CHARACTERISTICS FOR 74HCT
Voltages are referenced to GND (ground = 0)
Note to HCT types
1. The value of additional quiescent supply current ( I
CC
) for a unit load of 1 is given here.
To determine I
CC
per input, multiply this value by the unit load coefficient shown in the table below.
