74VHC4053, 74VHC4051, May 2007 74VHC4051, 8-Channel Analog Multiplexer tm T 8-Channel Analog Multiple riple 2-Channel Analog Multiple 74VHC4052, Dual 4-Channel Analog Multiplexer74VHC4053, Triple 2-Channel Analog Multiplexer Features General Description Wide analog input voltage range: ±6V These multiplexers are digitally controlled analog Low "ON" resistance: 50 Typ. (V = switches implemented in advanced silicon-gate CMOS CC­VEE 4.5V) 30 Typ. (V = technology. These switches have low "ON" resistance CC­VEE 9V) and low "OFF" leakages. They are bidirectional switches, Logic level translation to enable 5V logic with ±5V thus any analog input may be used as an output and analog signals vice-versa. Also these switches contain linearization cir- Low quiescent current: 80µA maximum cuitry which lowers the "ON" resistance and increases x Matched switch characteristic er 74VHC4052, switch linearity. These devices allow control of up to ±6V Pin and function compatible with the (peak) analog signals with digital control signals of 0 to 74HC4051/ 4052/4053 6V. Three supply pins are provided for VCC, ground, and x V . This enables the connection of 0­5V logic signals e EE r when V = CC 5V and an analog input range of ±5V when V = EE 5V. All three devices also have an inhibit control which when high will disable all switches to their offstate. All analog inputs and outputs and digital inputs are Dual 4-Channel Analog Multiple protected from electrostatic damage by diodes to VCCand ground. VHC4051: This device connects together the outputs of8 switches, thus achieving an 8 channel Multiplexer. Thebinary code placed on the A, B, and C select linesdetermines which one of the eight switches is "ON", andconnects one of the eight inputs to the common output. VHC4052: This device connects together the outputs of4 switches in two sets, thus achieving a pair of 4-channelmultiplexers. The binary code placed on the A, and Bselect lines determine which switch in each 4 channelsection is "ON", connecting one of the four inputs in eachsection to its common output. This enables the imple-mentation of a 4-channel differential multiplexer. VHC4053: This device contains 6 switches whose out-
