AD75019JPZ-REEL

Overview

The AD75019JPZ-REEL is a 16 × 16 crosspoint switch array containing 256 analog switches in a compact 44-lead PLCC package. It accommodates signal ranges up to supply rails of ±12 V or 24 V, with a typical on-resistance of 150 Ω at ±12 V and 300 Ω at ±5 V. The device features TTL/CMOS-compatible control lines and utilizes a serial input interface for simplified programming. Data is loaded via a dynamic 256-bit shift register clocked by SCLK (20 kHz min to 5 MHz max) and transferred to static latches via PCLK. Quiescent power consumption is low at 2 mW. The component supports cascading through a serial output pin.

Feature Summary

• Contains 256 individually programmable analog switches arranged in a 16x16 matrix.

• Features TTL/CMOS/microprocessor-compatible digital control interfaces.
• Utilizes a serial data input architecture to minimize control line count.

Applications

• Signal routing in communication systems
• Data acquisition system multiplexing
• Test and measurement equipment switching matrices

Procurement Notes

Verify the specific ordering suffix matches the required packaging format. Confirm that the RoHS compliant status aligns with environmental regulations for the target assembly process. Ensure the operating temperature range meets the application's thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-density crosspoint switching solution is required with minimal control wiring. Consider the on-resistance specifications relative to the intended signal voltage levels. Verify that the available clock frequencies meet the system's data loading speed requirements and that the power supply sequencing constraints can be satisfied within the design.

Part Context

This part belongs to the Analog Devices AD75019 family of crosspoint switch arrays. It is fabricated using BiMOS II technology, which integrates CMOS devices for low distortion switching and bipolar devices for ESD protection. The device is designed for applications requiring flexible interconnection between multiple input and output lines.

Replacement Considerations

The AD75019JPZ is the non-reel version of this component. No other direct substitute part numbers are documented in the official datasheet.

FAQ

What is the minimum clock rate required for the serial shift register?

The serial shift register is dynamic and requires a minimum clock rate of 20 kHz to prevent data loss.

How does the device handle power supply sequencing?

VDD must always be greater than (VCC – 0.5 V), and VSS must always be less than (DGND + 0.5 V). External diodes may be used if proper sequencing cannot be ensured.

Can multiple AD75019 devices be connected together?

Yes, multiple devices can be cascaded by connecting the SOUT output of one device to the SIN input of the next.
