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.
