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.
