| The 74HC4053 74HCT4053 is a high-speed Si-gate CMOS device and is pin compatiblewith the HEF4053B. It is specified in compliance with JEDEC standard no. 7A.The 74HC4053 74HCT4053 is triple 2-channel analog multiplexer/demultiplexer with acommon enable input E . Each multiplexer/demultiplexer has two independentinputs/outputs nY0 and nY1 , a common input/output nZ and three digital selectinputs Sn .WithE LOW, one of the two switches is selected low-impedance ON-state by S1 to S3.WithE HIGH, all switches are in the high-impedance OFF-state, independent of S1 to S3.VCC and GND are the supply voltage pins for the digital control inputs S1 to S3 andE .The VCC to GND ranges are 2.0 V to 10.0 V for 74HC4053 and 4.5 V to 5.5 V for74HCT4053. The analog inputs/outputs nY0 and nY1, and nZ can swing between VCCas 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 typicallyground . |
