DESCRIPTION

The 74LV4051 is a low-voltage CMOS device and is pin and function compatible with the 74HC/HCT4051.

The 74LV4051 is an 8-channel analog multiplexer/demultiplexer with three digital select inputs (S0 to S2) an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z).

With E LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2. With E 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 to 6.0 V. The analog inputs/outputs (Y0 to Y7 and Z) can swing between VCC

as a positive limit and VEE as a negative limit. VCC - VEE may not exceed 6.0 V. For operation as a digital multiplexer/demultiplexer,

VEE is connected to GND (typically ground).

QUICK REFERENCE DATA

NOTES:

1.CPD is used to determine the dynamic power dissipation (PD in mW) PD = CPD × VCC2 × fi ((CL + CS) × VCC2 × fo) where:

fi = input frequency in MHz; CL = output load capacity in pF;

fo = output frequency in MHz; CS = maximum switch capacitance in pF;

VCC = supply voltage in V;

((CL +CS) × VCC2 × fo) = sum of the outputs.

2.The condition is VI = GND to VCC.

NOTES:

1.Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

2.The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:

1.All typical values are measured at Tamb = 25°C.

2.At supply voltages approaching 1.2 V, the analog switch ON-resistance becomes extremely non-linear. Therefore, it is recommended that these devices be used to transmit digital signals only, when using these supply voltages.

3.RON (MAX) data is preliminary.
