FEATURES · Wide analog input voltage range: ± 5 V. · Low "ON" resistance: 80 (typ.) at VCC - VEE = 4.5 V 70 (typ.) at VCC - VEE = 6.0 V 60 (typ.) at VCC - VEE = 9.0 V · Logic level translation: to enable 5 V logic to communicate with ± 5 V analog signals · Typical "break before make" built in · Output capability: non-standard · ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4051 are high-speed Si-gate CMOS devices and are pin compatible with the "4051" of the
74HC/HCT4051
"4000B" series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4051 are 8-channel analog multiplexers/demultiplexers 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 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. 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 10.0 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground).

Note to ratings 1. To avoid drawing VCC current out of terminal Z, when switch current flows in terminals Yn, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal Z, no VCC current will flow out of terminals Yn. In this case there is no limit for the voltage drop across the switch, but the voltages at Yn and Z may not exceed VCC or VEE.
