MC14053BFELG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BFELG is a triple 2-channel analog multiplexer/demultiplexer manufactured by onsemi in the SOEIAJ-16 surface-mount package. It operates within a supply voltage range of 3.0 V to 18 V and supports an analog signal range of 3.0 V to 18 V. The device features low ON resistance, with maximum values of 1050 Ω at 5 V, 500 Ω at 10 V, and 280 Ω at 15 V (at 25°C). Propagation delay times are typically 65 ns, 20 ns, and 15 ns for supply voltages of 5 V, 10 V, and 15 V respectively. The bandwidth is specified at 17 MHz, and the operating temperature range extends from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Triple SPDT switch configuration providing three independent 2-to-1 analog channels
• Integrated level converter allowing digital control signals referenced to VSS while switching analog signals referenced to VEE
• Break-before-make switching function to prevent short circuits between channels during transitions
• Triple diode protection on control inputs to guard against high static voltages

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the relationship between VSS and VEE?

VEE must be less than or equal to VSS. The control inputs are referenced to VSS, while the analog switches reference their voltage range to VEE.

How does the device handle unused inputs?

Unused inputs must always be tied to an appropriate logic voltage level, such as VSS, VEE, or VDD. Unused outputs should be left open.

What is the typical noise performance?

The device exhibits low-noise characteristics, specified as 12 nV/√Hz typical at frequencies greater than or equal to 1.0 kHz.
