Philips Semiconductors Product specification
16-channel analog
multiplexer/demultiplexer
74HC/HCT4067
Note to AC CHARACTERISTICS FOR 74HC
1. Due to higher Z terminal capacitance (16 switches versus 1) the delay figures to the Z terminal are higher than those
to the Y terminal.
DC CHARACTERISTICS FOR 74HCT
Voltages are referenced to GND (ground = 0 V)
Note
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.
