PCA9534ADGVR

I/o Expanders Overview

The PCA9534ADGVR is a remote 8-bit I/O expander manufactured by Texas Instruments, designed for low-power applications. It operates on an I2C and SMBus interface with a maximum clock frequency of 400 kHz. The device supports a supply voltage range from 2.3 V to 5.5 V and functions within a temperature range of -40°C to +85°C. It features configuration registers and an interrupt pin for efficient status monitoring. The component is housed in a 16-TVSOP package.

I/o Expanders Feature Summary

• Supports I2C and SMBus communication protocols for system integration
• Includes configuration registers for flexible input/output direction control
• Features an interrupt output pin to signal external events

I/o Expanders Applications

• Portable consumer electronics requiring low power consumption
• Industrial control systems utilizing I2C/SMBus networks
• Embedded systems needing additional general-purpose I/O lines

I/o Expanders Procurement Notes

Verify the specific suffix DGVR confirms the TVSOP-16 package and tape-and-reel packaging format. Confirm RoHS compliance and lead times directly with authorized distributors or Texas Instruments, as availability varies. Ensure the ordering part number matches the required operating temperature range and voltage specifications for your design.

I/o Expanders Selection Notes

Select this component when an 8-bit I/O expansion solution is required with I2C compatibility. Compare against the TCA9534 series if lower voltage operation below 2.3 V is needed. Verify that the TVSOP-16 package fits the PCB layout constraints and that the 400 kHz speed meets the system bus requirements.

I/o Expanders Part Context

This part belongs to the PCA9534A family of remote 8-bit I/O expanders. It shares functional similarities with other devices in the series but differs in package type and specific suffix designations. The DGVR suffix specifically denotes the TVSOP-16 package variant intended for surface-mount assembly.

I/o Expanders Replacement Considerations

Texas Instruments recommends the TCA9534PWR as a manufacturer-recommended replacement. Verify electrical compatibility and pinout alignment before substitution. Other variants like PCA9534DGVR may serve as direct replacements if package and suffix differences are accounted for.
