Overview
The AD7501KN is a monolithic CMOS 8-channel analog multiplexer that switches one of eight inputs to a common output based on three binary address lines and an enable input. It features TTL/DTL and CMOS logic compatibility with a typical power dissipation of 30 µW. The device operates within a commercial temperature range of 0°C to +70°C. Key electrical parameters include a maximum on-resistance (Ron) of 300 Ω, a typical Ron of 170 Ω, and switching times (ton/toff) of 0.8 µs.
Feature Summary
- Monolithic CMOS construction for low power consumption
- Direct interface with DTL, TTL, and CMOS logic families
- Single-ended 8-to-1 multiplexing architecture
Applications
- Data acquisition systems requiring signal routing
- Process control instrumentation
- Industrial automation signal conditioning
Procurement Notes
Verify the specific suffix KN indicates the commercial temperature grade (0°C to +70°C) and PDIP package. Confirm lead-free status as older datasheets may list non-compliant variants. Check current manufacturing status as this component family has been marked obsolete in some distributor records. Ensure ESD precautions are observed during handling due to CMOS sensitivity.
Selection Notes
Select the AD7501KN when an active-high enable logic is required, distinguishing it from the AD7503 which uses inverted enable logic. Consider the AD7502 if dual 4-channel multiplexing is needed instead of a single 8-channel path. Evaluate the KQ or SQ suffixes if industrial (-25°C to +85°C) or extended (-55°C to +125°C) temperature ranges are necessary for the application environment.
Part Context
The AD7501 belongs to the AD7501/AD7502/AD7503 family of CMOS analog multiplexers manufactured by Analog Devices. This series provides versatile signal switching solutions with direct logic compatibility. The AD7501 specifically offers an 8-channel configuration with standard enable logic, serving as a foundational component for analog signal routing in mixed-signal circuits.
Replacement Considerations
Public documentation identifies the ADG1408YRUZ as a similar replacement option. Verify functional equivalence regarding channel count, on-resistance, and logic compatibility before substitution. Note that the AD7501KN itself is listed as obsolete in some sources, necessitating careful validation of long-term availability for new designs.
