Overview
The AD7501JN is a monolithic CMOS 8-channel analog multiplexer. It switches one of eight inputs to a common output based on three binary address lines and an enable input. The device features DTL/TTL/CMOS direct interface compatibility. Key electrical parameters include a typical on-resistance (RON) of 170 Ω, maximum off-state leakage current of 2 nA, and power dissipation of 30 μW. Switching times are typically 0.8 μs for both turn-on and turn-off.
Feature Summary
- Monolithic CMOS construction for low power consumption
- Direct interface with DTL, TTL, and CMOS logic families
- Single 8-to-1 channel switching configuration
- Output enable control for bus isolation
Applications
- Data acquisition systems requiring signal routing
- Industrial process control instrumentation
- Automotive electronic testing equipment
- Communication system signal conditioning
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current guide, as the JN designation indicates a PDIP package. Confirm that the commercial temperature range meets application requirements. Check for obsolete status or lifecycle notices from Analog Devices before finalizing procurement plans. Ensure ESD precautions are observed during handling due to CMOS sensitivity.
Selection Notes
Select this component when a single 8-channel multiplexing function is required with standard logic compatibility. Compare RON uniformity and leakage specifications against alternative CMOS multiplexers if high precision is needed. Consider the AD7503 if inverted enable logic is preferred. Evaluate thermal derating requirements for enclosed environments.
Part Context
The AD7501 series belongs to Analog Devices' portfolio of CMOS analog switches. It serves as a fundamental building block for signal routing in mixed-signal systems. The device complements other data converters and signal conditioners by providing flexible input selection capabilities for microprocessor-based architectures.
Replacement Considerations
The AD7503 is functionally identical but utilizes inverted enable logic. Verify pinout compatibility when substituting. No direct public substitutes are confirmed in the provided documentation; consult official cross-reference guides for modern equivalents.
