Description
The 'HC4351, 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.
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.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. In certain applications, the external load-resistor current may include both V
CC
and signal-line components. To avoid drawing V
CC
current
when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed 0.6V (cal-
culated from R
ON
values shown in the DC Electrical Specifications table). No V
CC
current will flow through R
L
if the switch current flows
into terminal 3 on the 'HC4351 and CD74HCT4351; terminals 3 and 13 on the CD74HC4352.
4. The package thermal impedance is calculated in accordance with JESD 51-7.
