Description
The HCF4051B device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 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 – VSS and VDD – VEE supply 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 O (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 kO
- 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 O (typ.) for VDD – VEE = 15 V
- Wide range of digital and analog signal levels: digital 3 to 20, analog to 20 V p.p.
- Quiescent current specified up to 20 V
- 5 V, 10 V and 15 V parametric ratings
- ESD performance
- HBM: 2 kV
- MM: 200 V
- CDM: 750 V
- Input leakage current II = 100 nA (max.) at VDD = 18 V, TA = 25 °C
- 100 % tested for quiescent current
