NLAS4051
Analog Multiplexer/
Demultiplexer
TTL Compatible, SinglePole, 8Position
Plus Common Off
The NLAS4051 is an improved version of the MC14051 and
MC74HC4051 fabricated in submicron Silicon Gate CMOS
technology for lower R
DS(on)
resistance and improved linearity with
low current. This device may be operated either with a single supply or
dual supply up to
3 V to pass a 6 V
PP
signal without coupling
capacitors.
When operating in single supply mode, it is only necessary to tie
V
EE
, pin 7 to ground. For dual supply operation, V
EE
is tied to a
negative voltage, not to exceed maximum ratings.
Improved R
DS(on)
Specifications
Pin for Pin Replacement for MAX4051 and MAX4051A
One Half the Resistance Operating at 5.0 Volts
Single or Dual Supply Operation
Single 2.55 Volt Operation, or Dual
3 Volt Operation
With V
CC
of 3.0 to 3.3 V, Device Can Interface with 1.8 V Logic,
No Translators Needed
Address and Inhibit Logic are OverVoltage Tolerant and May Be
Driven Up +6 V Regardless of V

8. At supply voltage (V
CC
) approaching 2.5 V the analog switch onresistance becomes extremely nonlinear. Therefore, for low voltage
operation it is recommended that these devices only be used to control digital signals.
