8-channel analog multiplexer/demultiplexer
General descriptionThe 74LV4051 is an 8-channel analog multiplexer/demultiplexer with three digital select
inputs (S0to S2),an active-LOW enable input (E), eight independent inputs/outputs (Y0to
Y7) and a common input/output (Z). It is a low-voltage Si-gate CMOS device that is pin
and function compatible with 74HC4051 and 74HCT4051. With E LOW, one of the eight
switchesis selected (low impedance ON-state)byS0to S2. WithE HIGH,all switches are
in the high-impedance OFF-state, independent of S0 to S2.
VCC and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E).
The VCC to GND ranges are 1.0 V to 6.0 V. The analog inputs/outputs (Y0 to Y7, and Z)
can swing between VCCasa positive limit and VEEasa negative limit. VCC− VEE may not
exceed 6.0V . For operation as a digital multiplexer/demultiplexer, VEE is connected to
GND (typically ground).
Features Optimized for low-voltage applications: 1.0 V to 6.0V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6V Low ON resistance: 145 Ω (typical) at VCC − VEE= 2.0 V 80 Ω (typical) at VCC − VEE= 3.0 V 60 Ω (typical) at VCC − VEE= 4.5 V Logic level translation: To enable 3 V logic to communicate with ±3 V analog signals Typical ‘break before make’ built in ESD protection: HBM JESD22-A114E exceeds 2000V MM JESD22-A115-A exceeds 200V Multiple package options Specified from −40 °Cto+85 °C and from −40°Cto +125°C

6.1 Function table[1]H= HIGH voltage level;= LOW voltage level;= don’t care.
Limiting values[1] To avoid drawing VCC current out of terminal Z, when switch current flows into terminals Yn, the voltage drop across the bidirectional
switch must not exceed 0.4 V. If the switch current flows into terminal Z, no VCC current will flow out of terminals Yn, and in this case
there is no limit for the voltage drop across the switch, but the voltages at Yn and Z may not exceed VCC or VEE.
[2] The minimum input voltage rating may be exceeded if the input current rating is observed.
[3] For DIP16 packages: above 70 °C the value of Ptot derates linearly with 12 mW/K.
For SO16 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K.
For SSOP16 and TSSOP16 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN16 packages: above 60 °C the value of Ptot derates linearly with 4.5 mW/K.
