Overview
The MUX507IPWR is a dual 8:1 analog multiplexer switch manufactured by Texas Instruments, housed in a TSSOP-28 surface-mount package. It operates on a single supply voltage ranging from 10 V to 36 V or a dual supply of ±5 V to ±18 V. The device features an extremely low on-state leakage current of 1 pA and a maximum on-resistance of 430 Ohms. Switching performance includes a maximum turn-on time of 149 ns and a turn-off time of 102 ns. It provides typical off-isolation of -97 dB and functions reliably within an operating temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low on-state leakage current specification suitable for high-impedance signal paths
- Dual independent 8-to-1 channel configuration for complex signal routing
- Wide single and dual power supply compatibility for diverse system architectures
Applications
- High-precision data acquisition systems requiring minimal signal distortion
- Medical instrumentation with strict leakage current constraints
- Industrial process control sensor multiplexing
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the procurement source provides valid RoHS compliance information as indicated in component databases. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical parameter consistency before finalizing orders.
Selection Notes
Select this component when ultra-low leakage is critical, as standard CMOS multiplexers typically exhibit higher leakage currents. The wide supply voltage range allows flexibility in power design compared to lower-voltage alternatives. Consider the TSSOP-28 package dimensions for PCB layout constraints. Verify that the 430 Ohm on-resistance meets the signal integrity requirements of the specific application circuit.
Part Context
This component belongs to the MUX507 series of analog switches, designed specifically for applications demanding high isolation and low leakage. It complements other precision analog interface devices from Texas Instruments, offering a robust solution for multiplexing multiple input signals into a single output path while maintaining signal fidelity across industrial temperature ranges.
Replacement Considerations
The MUX507IDR serves as a pin-compatible alternative in a SOIC-28 package. Evaluate thermal dissipation and board space requirements when substituting between TSSOP and SOIC packages. Confirm that the replacement maintains the same 1 pA leakage characteristic and 430 Ohm on-resistance limits for equivalent performance.
