The 74LV4052 is a low-voltage CMOS device and is pin and function compatible with the 74HC/HCT4052. The 74LV4052 is a dual 4-channel analog multiplexer/demultiplexer with a common select logic. Each multiplexer has four independent inputs/outputs (nY0 to nY3) and a common input/output (nZ). The common channel select logics include two digital select inputs (S0 and S1) and an active LOW enable input (E). With E LOW, one of the four switches is selected (low impedance ON-state) by S0 and S1. With E HIGH, all switches are in the high impedance OFF-state, independent of S0 and S1. VCC and GND are the supply voltage pins for the digital control inputs (S0, S1 and E). The VCC to GND ranges are 1.0 V to 6.0 V. The analog inputs/outputs (nY0, to nY3, and nZ) can swing between VCC as a positive limit and VEE as a negative limit. VCC – VEE may not exceed 6.0 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground).
- Optimized for low voltage applications: 1.0 to 6.0 V
- Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
- Low ON resistance:
- 145 O (typical) at VCC – VEE = 2.0 V
- 90 O (typical) at VCC – VEE = 3.0 V
- 60 O (typical) at VCC – VEE = 4.5 V
- Logic level translation:
- To enable 3 V logic to communicate with ±3 V analog signals
- Typical “break before make” built in
- ESD protection:
- HBM JESD22-A114E exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- Multiple package options
- Specified from -40 °C to +85 °C and from -40 °C to +125 °C
