High Speed CMOS Logic
Analog Multiplexers/Demultiplexers with Latch
September 1998 - Revised May 2000
Features
LSTTL with the low power consumption of standard CMOS
integrated circuits.
• Wide Analog Input Voltage Range . . . . . . . . . ± 5V (Max)
These analog multiplexers/demultiplexers are, in essence,
the HC/HCT4015 and HC4052 preceded by address lat che s
that are controlled by an active low La tch 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:
5. 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.

q JA is measured with the component mounted on an evaluation PC board in free air.
