XS3A4051
Single low-ohmic 8-channel analog switch
The XS3A4051 is a low-ohmic 8-channel analog switch, suitable for use as an analog or digital multiplexer/demultiplexer. The XS3A4051 has three digital select inputs (S1 to S3), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). All eight switches share an enable input (E). A HIGH on E causes all switches into the high impedance OFF-state, independent of Sn.
Schmitt trigger action at the digital inputs makes the circuit tolerant to slower input rise and fall times. Low threshold digital inputs allows this device to be driven by 1.8 V logic levels in 3.3 V applications without significant increase in supply current ICC. This makes it possible for the XS3A4051 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation. The XS3A4051 allows signals with amplitude up to VCC to be transmitted from Z to Yn or from Yn to Z. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures minimal attenuation and distortion of transmitted signals.
Features and benefits
