HCF4051BE Product Details

The HCF4051BE device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages.

The HCF4051BE analog multiplexer/demultiplexer is a digitally controlled analog switch having low ON impedance and very low OFF leakage current. This multiplexer circuit dissipates extremely low quiescent power over the full VDD- VSSand VDD- VEEsupply voltage range, independent of the logic state of the control signals.
This device is a single 8-channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. When a logic “1” is present at the inhibit input terminal all channels are off.



  • Low “ON” resistance: 125 Ω (typ.)
  • Over 15 V p.p signal-input range for VDD- VEE= 15 V
  • High “OFF” resistance, channel leakage: ± 100 pA (typ.) at VDD- VEE= 18 V
  • Binary address decoding on chip
  • High degree of linearity: < 0.5 % distortion typ. at fIS= 1 KHz, VIS= 5 Vpp, VDD- VSS≥ 10 V, RL= 10 kΩ
  • Very low quiescent power dissipation under all digital control input and supply conditions: 0.2 μW (typ.) VDD- VSS= VDD- VEE= 10 V
  • Matched switch characteristics: RON= 5 Ω (typ.) for VDD- VEE= 15 V
