The 74HC4052; 74HCT4052 is a high-speed Si-gate CMOS device and is pin compatible with the HEF4052B. The device is specified in compliance with JEDEC standard no. 7A. The 74HC4052; 74HCT4052 is a dual 4-channel analog multiplexer/demultiplexer with common select logic. Each multiplexer has four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ). The common channel select logics include two digital select inputs (pins S0 and S1) and an active LOW enable input (pin E). When pin E = LOW, one of the four switches is selected (low-impedance ON-state) with pins S0 and S1. When pin E = HIGH, all switches are in the high-impedance OFF-state, independent of pins S0 and S1. VCC and GND are the supply voltage pins for the digital control inputs (pins S0, S1 and E). The VCC to GND ranges are 2.0 V to 10.0 V for the 74HC4052 and 4.5 V to 5.5 V for the 74HCT4052. The analog inputs/outputs (pins nY0 to nY3 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).
- Wide analog input voltage range from -5 V to +5 V
- Low ON resistance:
- 80 ? (typical) at VCC – VEE = 4.5 V
- 70 ? (typical) at VCC – VEE = 6.0 V
- 60 ? (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
- Complies with JEDEC standard no. 7A
- ESD protection:
- HBM JESD22-A114F exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- CDM JESD22-C101E exceeds 1000 V
- Specified from -40 ? to +85 ? and -40 ? to +125 ?
