Replacement verdict
Not a drop-in replacement
The AD75019JPZ and AD75089JP are not functionally interchangeable. The AD75019JPZ is a 16×16 crosspoint switch array, while the AD75089JP is an 8-channel analog multiplexer; they differ in switch architecture, channel count, package footprint, and control interface, so substituting one for the other requires a full circuit redesign rather than a direct swap.

Key electrical and mechanical differences between the two devices
| Parameter | AD75019JPZ | AD75089JP | Why it matters |
|---|---|---|---|
| Switch Configuration | 16 x 16 crosspoint array | 8-channel differential multiplexer | Defines the signal routing topology; a crosspoint array and a differential mux are not functionally interchangeable in most circuits. |
| Number of Channels / Switches | 256 crosspoint switches | 8 differential channels (16 switches) | Determines how many independent signal paths can be routed, directly affecting system capacity and board layout. |
| On-Resistance (RON) | Approx. 300 Ω (typ) | Approx. 300 Ω (typ) | Series resistance affects signal attenuation and accuracy; similar values suggest comparable signal integrity for low-current paths. |
| Package Type | 44-lead PLCC | 28-lead PLCC | Package footprint and pin count must match the PCB layout; different packages are not drop-in compatible. |
| Control Interface | Serial (SPI-compatible) shift register | Parallel address lines | The digital control scheme dictates microcontroller pin usage and firmware; serial vs parallel control requires different driving logic. |
| Supply Voltage Range | ±5 V to ±15 V dual supply | ±5 V to ±15 V dual supply | Operating supply range must match the system rails; identical ranges allow reuse of the same power design. |
| Analog Signal Range | Rail-to-rail (within supply) | Rail-to-rail (within supply) | Determines the allowable input signal swing; matching ranges ensure signals are not clipped in either device. |
| Operating Temperature Range | 0 °C to +70 °C (commercial) | 0 °C to +70 °C (commercial) | Temperature rating affects reliability and suitability for the target environment; matching ratings allow use in the same application class. |

Frequently asked questions
Are the AD75019JPZ and AD75089JP functionally interchangeable?
No. The AD75019JPZ is a 16 x 16 crosspoint switch array, while the AD75089JP is an 8-channel analog multiplexer. They differ in switch topology, channel count, and control interface, so they are not direct substitutes.
What are the package and mounting differences between the AD75019JPZ and AD75089JP?
The AD75019JPZ is supplied in a 44-lead PLCC package (P-44A) and is surface-mount. The AD75089JP is supplied in a 28-lead PLCC package and is also surface-mount. The different lead counts and footprints prevent PCB-level interchangeability.
How do the switch configurations of the AD75019JPZ and AD75089JP differ?
The AD75019JPZ provides a 16 x 16 crosspoint matrix, allowing any of 16 inputs to be connected to any of 16 outputs. The AD75089JP is an 8-channel multiplexer/demultiplexer that selects one of eight channels, so the two devices serve different signal-routing architectures.
Do the AD75019JPZ and AD75089JP use the same control interface?
No. The AD75019JPZ is controlled through a serial interface for programming the crosspoint matrix. The AD75089JP uses 3-bit binary address lines plus an enable input to select one of eight channels. The control schemes are not compatible.
What are the supply voltage requirements for the AD75019JPZ and AD75089JP?
Both devices operate from dual supplies. The AD75019JPZ is specified for ±10 V to ±15 V dual supplies, and the AD75089JP is specified for ±10 V to ±15 V dual supplies as well. Designers should confirm exact limits in the respective manufacturer datasheets.
Can the AD75019JPZ and AD75089JP be used in the same signal chain?
They can coexist in a system but serve different roles: the AD75019JPZ for full crosspoint routing and the AD75089JP for channel selection. They are not pin-compatible or functionally equivalent, so each must be designed into its own circuit location.
Which device is better suited for routing multiple signals to multiple destinations?
The AD75019JPZ is suited for many-to-many routing because its 16 x 16 crosspoint array can connect any input to any output. The AD75089JP is suited for one-of-eight selection and cannot provide arbitrary many-to-many connectivity.
