SN74F126NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F126NSR is a quad bus buffer gate manufactured by Texas Instruments, belonging to the SN74F logic series. It features four non-inverting channels with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation. Key electrical parameters include a propagation delay of 8 ns at 5 V, a low-level output current capability of 24 mA, and a high-level output current of -3 mA. It functions within an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the component meets the required industrial temperature specifications for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring buffered signals with controlled impedance and three-state bus management capabilities. Consider the SN74F series performance characteristics regarding speed and drive strength relative to system timing requirements. Evaluate pinout compatibility and thermal dissipation needs associated with the SOIC-14 form factor during PCB layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F family of high-speed CMOS logic devices produced by Texas Instruments. The F series is characterized by faster switching speeds compared to standard LS logic while maintaining compatible pinouts. The SN74F126 specifically addresses applications needing isolated buffering with tri-state control on multiple lines simultaneously.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74F126N: Identical functional logic but utilizes a PDIP-14 through-hole package instead of surface mount. SN74F125NSR: Similar quad buffer functionality but includes active-low enable inputs rather than active-high, requiring logic inversion adjustments.
