74LV4051

General 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.

V_CC and GND are the supply voltage pins for the digital control inputs (S₀ to S₂and E). The V_CC to GND ranges are 1.0 to 6.0 V. The analog inputs/outputs (Y₀ to Y₇ and Z) can swing between V_CC as a positive limit and V_EE as a negative limit. V_CC - V_EE may not exceed 6.0 V. For operation as a digital multiplexer/demultiplexer, V_EE is connected to GND (typically ground).

Features

• Optimized for low voltage applications: 1.0 to 6.0 V
• Accepts TTL input levels between V_CC = 2.7 V and V_CC = 3.6 V
• Low typ "ON" resistance:
  60 Ohm at V_CC - V EE = 4.5 V
  90 Ohm at V_CC - V_EE = 3.0 V
  145 Ohm at V_CC - V_EE = 2.0 V
• Logic level translation: to enable 3 V logic to communicate with ± 3 V analog signals
• Typical "break before make" built in
• Output capability: non-standard
• I_CC category: MSI
