The NMUX1237 is a single-pole double-throw analog switch with a digital select input (S), two independent inputs/outputs (Y0 and Y1) and a common input/output (Z). The digital select input (S) supports 1.8 V logic thresholds independent of operating voltage. This feature enables compatibility in applications that combine low voltage digital I/Os with monitoring of mid voltage analog signals. The NMUX1237 is specifically designed for applications that are sensitive to signal overshoot.
Features and benefits
Integrated suppression circuit to minimize signal overshoot
1.8 V control logic thresholds across supply operating range
Ioff circuitry
Enables wider latitude for power sequencing considerations
Isolates backflow between supply rail and any biased digital/analog input when VCC = 0 V
Prevents any biased digital/analog input from backpowering VCC when VCC = 0 V
Analog switch path maintains isolation state
Wide supply voltage range from 1.08 V to 5.5 V
Very low ON resistance: 4 Ω
Low supply current: 5 nA
Rail-to-rail operation
Bidirectional signal path
Break-before-make switching
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C2b exceeds 750 V
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
