Description

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.

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 (
Two Enable inputs, one active low (

E1), and the other active

LE).

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:

5. In certain applications, the external load-resistor current may include both VCCandsignal-linecomponents.ToavoiddrawingVCCcurrent
when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed 0.6V (cal­culated from RONvalues shown in the DC Electrical Specifications table). No VCCcurrent will flow through RLif the switch current flows
into terminal 3 on the HC/HCT4351; terminals 3 and 13 on the HC4352.
