Functional Description

74HC4051FT: 8-Channel Analog Multiplexer/Demultiplexer

74HC4052FT: Dual 4-Channel Analog Multiplexer/Demultiplexer

General

The 74HC4051FT/74HC4052FT are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricated

with silicon gate CMOS technology. They achieve the high speed operation similar to equivalent LSTTL while

maintaining the CMOS low power dissipation.

The 74HC4051FT has an 8 channel configuration and the 74HC4052FT has a 4 channel × 2 configuration.

The digital signal to the control terminal turns ON the corresponding switch of each channel a large amplitude

signal (VCC - VEE) can then be switched by the small logical amplitude (VCC - GND) control signal.

For example, in the case of VCC = 5 V, GND = 0 V, VEE = -5 V, signals between -5 V and +5 V can be switched from

the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can be

connected to circuits with low input impedance.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features

(1) Wide operating temperature range: Topr = -40 to 125

(2) Low power dissipation: ICC = 4.0 μA (max) (VCC = 6.0 V, VEE = GND, Ta = 25 )

(3) Low ON-resistance: RON = 50 Ω (typ.) at VCC - VEE = 9 V

(4) High degree of linearity: THD = 0.020 (typ.) at VCC - VEE = 9 V
