SN74AUC32245ZKER

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC32245ZKER is a 32-bit bus transceiver with three-state outputs manufactured by Texas Instruments. It operates within a voltage range of 1.65 V to 3.6 V and supports mixed-mode signal operation, allowing compatibility between different logic families. The device features an Ioff function that supports partial-power-down mode to prevent excessive current draw when the device is powered down but the system is active. It is housed in a 96-pin LFBGA package (BGA96, 6x16, 32) and is rated for an operating temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected variant matches the required pinout and electrical specifications for the target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high pin density and low voltage operation. The 96-pin BGA package offers significant space savings compared to through-hole alternatives. Consider the Ioff feature if the system requires hot-swapping or partial powering capabilities without damaging connected peripherals.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the AUC series of Texas Instruments logic components, which are optimized for ultra-low voltage applications. The 32-bit configuration provides wide data path capability, making it suitable for high-bandwidth interfaces where minimizing component count on the PCB is critical for performance and cost efficiency.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 32-bit bus transceivers from the same family, such as the SN74AUC32245PWPR, provided the package type change from BGA to TSSOP is acceptable for the layout.
