Features  
Description  
• Wide Analog Input Voltage Range . . . . . . . . . ±5V (Max) The  
Harris  
CD74HC4351,  
CD74HCT4351  
and  
CD74HC4352 are digitally controlled analog switches which  
utilize silicon-gate CMOS technology to achieve operating  
speeds similar to LSTTL with the low power consumption of  
standard CMOS integrated circuits.  
• Low “On” Resistance

• Low Crosstalk Between Switches  
• Fast Switching and Propagation Speeds  
• “Break-Before-Make” Switching  
These analog multiplexers/demultiplexers are, in essence,  
the HC/HCT4015 and HC4052 preceded by address latches  
that are controlled by an active low Latch Enable input (LE).  
Two Enable inputs, one active low (E1), and the other active  
high (E2) are provided allowing enabling with either input  
voltage level.
