TCA9536CDTMR

Overview

The TCA9536CDTMR is a remote 4-bit I2C and SMBus I/O expander manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V, supporting 5-V tolerant I/O ports. The device features a 1-MHz Fast mode plus interface, software-reset capability, and integrated pull-up resistors on P ports. It includes configuration, input/output, polarity inversion, and special function registers. The P3 pin can be repurposed as an open-drain interrupt output. It provides high-current drive for LEDs and includes ESD protection exceeding JESD 22 standards.

Feature Summary

I2C to GPIO expander with 5-V tolerant I/O ports
Software reset via I2C General Call
Software-enabled integrated pull-up resistors on P ports
P3 can be repurposed as INT output

Applications

Wearables
Mobile phones
Gaming consoles

Procurement Notes

Verify the specific ordering suffix 'DTMR' against the manufacturer's current orderable addendum to confirm the package type and tape-and-reel quantity. Ensure the component meets RoHS requirements for the intended application. Cross-reference the datasheet revision date to confirm the document status is production data rather than advanced information.

Selection Notes

Select this component when a compact 4-bit I/O expansion solution is required for microcontroller systems. It is suitable for applications needing 5-V tolerance on I/O lines while operating at lower core voltages. Consider the X2SON-8 package for space-constrained designs. Verify that the interrupt functionality and internal pull-up configurations meet the system's electrical requirements.

Part Context

The TCA9536CDTMR belongs to the TCA9536 series of I/O expanders from Texas Instruments. It is part of a family designed for general-purpose remote I/O expansion via the I2C interface. The device is often used in personal electronics and servers where additional GPIOs are needed without consuming processor pins.

Replacement Considerations

The PCA9536 is a similar remote 4-bit I2C and SMBus I/O expander with configuration registers. Verify pin compatibility and register mapping before substitution.
