74AC11245NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC11245 is an octal bus transceiver with three-state outputs designed for asynchronous two-way communication between data buses. It utilizes the EPIC (Enhanced-Performance Implanted CMOS) process and operates within a supply voltage range of 3 V to 5.5 V. The device features a flow-through architecture optimized for PCB layout and center-pin VCC/GND configurations to minimize high-speed switching noise. It supports bidirectional data transmission controlled by a DIR input, with isolation provided by an OE input. Operating temperatures range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, as the datasheet lists multiple options including SOIC (DW), SSOP (DB), TSSOP (PW), and PDIP (NT). Confirm the ordering suffix matches the desired tape-and-reel or tube quantity. Check current production status, as some variants are marked obsolete while others remain active. Ensure compatibility with the target operating temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with low propagation delay. The AC logic family offers faster switching speeds compared to standard LS or HC families. Consider the available package types based on space constraints and thermal requirements. Verify that the system power supply falls within the 3 V to 5.5 V operating range to ensure correct logic levels.
