74AC11245NSRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC11245NSRE4 is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It utilizes EPIC (Enhanced-Performance Implanted CMOS) technology and operates within a supply voltage range of 3 V to 5.5 V. The device supports bidirectional data transmission between two buses, controlled by a direction input and an output-enable input. It features a flow-through architecture for optimized PCB layout and center-pin VCC/GND configurations to minimize high-speed switching noise. The component is characterized for operation from –40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and lead finish when ordering, as the NSRE4 suffix indicates a plastic small-outline package. Confirm RoHS compliance status and moisture sensitivity level requirements against current datasheet revisions. Ensure the design accounts for the absolute maximum ratings, particularly regarding continuous output current and power dissipation limits at elevated temperatures.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed bidirectional data transfer with low propagation delay. The AC series offers faster switching characteristics compared to standard logic families. Consider the 24-pin SOIC package constraints and verify that the system voltage falls within the 3 V to 5.5 V operating range. Evaluate thermal management needs based on the specified power dissipation capabilities.
