HEF4051BP

The HEF4051BP is designed as an 8-channel analogue multiplexer /demultiplexer with three address inputs (A0 to A2), an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). HEF4051BP contains eight bidirectional analogue switches, each with one side connected to an independent input/output (Y0 to Y7) and the other side connected to a common input/output (Z).

Some limiting ratings of HEF4051BP has been concluded as follow. Its supply voltage with reference to Vdd would be from -18V to +0.5V. To avoid drawing Vdd current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional switch must not exceed 0,4V. If the switch current flows into terminal Z, no Vdd current will flow out of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed Vdd or Vee.

Also some electrical characteristics of HEF4051BP are concluded as follow. (1)Its ON resistance with test conditios of Vis=0 to Vdd-Vee would be typ 350 and max 2500 at Vdd-Vee=5V and would be typ 80 and max 245 at 10V and would be typ 60 and max 175 at 15V. (2)Its ON resistance with conditions of Vis=0 would be typ 115 and max 340 at Vdd-Vee=5V and would be typ 50 and max 160 at 10V and would be typ 40 and max 115 at 15V. (3)Its ON resistance with test conditions of Vis=Vdd-Vee would be typ 120 and max 365 at Vdd-Vee=5V and would be typ 65 and max 200 at 10V and would be typ 50 and max 155 at 15V. (4)Its off-state leakage current all channels off would be max 100nA at Vdd-Vee=15V. (5)Its off-state leakage current any channel would be max 200nA at Vdd-Vee=15V.  (6)Its propagation delays Vis to Vos high to low would be typ 15ns and max 30ns at Vdd=5V and would be typ 5ns and max 10ns at Vdd=10V and would be typ 5ns and max 10ns at Vdd=15V. (7)Its propagation delays Vis to Vos low to high would be typ 15ns and max 30ns at Vdd=5V and would be typ 5ns and max 10ns at Vdd=10V and would be typ 5ns and max 10ns at Vdd=15V. And so on.
