SN74F245NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F245NSR is an octal bus transceiver manufactured by Texas Instruments, belonging to the SN74F logic series. It features eight non-inverting channels with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical specifications include a propagation delay of 7 ns, a low-level output current capability of 64 mA, and a high-level output current of -15 mA. It functions reliably across an operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the SOIC-20 footprint matches the target PCB design guidelines. Ensure the component meets the necessary RoHS compliance standards for the intended market. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed switching performance is required alongside robust drive capabilities for standard 5V logic applications. The F-series technology offers faster propagation delays compared to HC or HCT variants. Consider the thermal characteristics of the SOIC package if multiple units are placed in close proximity on the circuit board to ensure reliable operation within the specified temperature limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader SN74xx logic family, specifically designed for general-purpose digital applications. It serves as a standard interface solution for connecting microprocessors, memory devices, and peripheral circuits. The SN74F245 variant represents a fast version within the lineage, balancing speed and power consumption for typical industrial and commercial electronic equipment designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74F245DWR is a pin-compatible alternative featuring the same logical function but packaged in a wider SOIC-20 (DW) format. Designers must verify mechanical clearance and solder mask definitions when substituting between NS and DW package styles.
