Product specication
Triple 2-channel analog
multiplexer/demultiplexer with latch
74HC/HCT4353
ADDITIONAL AC CHARACTERISTICS FOR 74HC/HCT
Recommended conditions and typical values
GND = 0 V; Tamb =25 °C
Notes to the AC characteristics
1. Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 ).
2. Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 ).
General note
Vis is the input voltage at an nYn or nZ terminal, whichever is assigned as an input.
Vos is the output voltage at an nYn or nZ terminal, whichever is assigned as an output.
