General description

The 74HC4053; 74HCT4053 is a high-speed Si-gate CMOS device and is pin compatible with the HEF4053B. It is specified in compliance with JEDEC standard no. 7A.

The 74HC4053; 74HCT4053 is triple 2-channel analog multiplexer/demultiplexer with a common enable input (E). Each multiplexer/demultiplexer has two independent inputs/outputs (nY0 and nY1), a common input/output (nZ) and three digital select inputs (Sn). With E LOW, one of the two switches is selected (low-impedance ON-state) by S1 to S3. With E 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 (S0 to S2, and E). The VCC to GND ranges are 2.0 V to 10.0 V for 74HC4053 and 4.5 V to 5.5 V for 74HCT4053. The analog inputs/outputs (nY0 to nY1, and nZ) 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).

Features and benefits

■ Wide analog input voltage range from ?5 V to +5 V

■ Low ON resistance:

?? 80 Ω (typical) at VCC - VEE = 4.5 V

?? 70 Ω (typical) at VCC - VEE = 6.0 V

?? 60 Ω (typical) 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

■ ESD protection:

?? HBM JESD22-A114F exceeds 2000 V

?? MM JESD22-A115-A exceeds 200 V

?? CDM JESD22-C101E exceeds 1000 V

■ Multiple package options

■ Specified from ?40°C to +85°C and ?40°C to +125°C

Applications

■ Analog multiplexing and demultiplexing

■ Digital multiplexing and demultiplexing

■ Signal gating
