N74F126D,623

Buffers, Drivers, Receivers, Transceivers Overview

The N74F126D,623 is a quad buffer with 3-state outputs manufactured by Nexperia under the 74F logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. The device features four non-inverting data inputs (D0–D3) and four corresponding outputs (Q0–Q3), controlled by active-high output enable signals (OE0–OE3). Typical propagation delay is 5.0 ns at 5 V, with maximum limits reaching 8.5 ns. High-level output current is -15 mA, while low-level output current reaches 64 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• High impedance NPN base inputs reduce circuit loading in both high and low states.
• Quad configuration provides four independent non-inverting buffers with 3-state control.
• Active-high output enables allow precise management of bus line access.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented transmissions
• Clock drivers
• Buffering of I/O circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be subject to discontinuation. Ensure the SOIC-14 package matches design requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring fast switching speeds and high fan-out capabilities typical of the 74F series. Verify that the active-high enable logic aligns with system control signals. Consider thermal dissipation requirements given the bipolar technology characteristics.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74F family of high-speed TTL logic devices originally developed by Philips Semiconductors. The 'D' suffix indicates a 14-pin plastic small outline package (SOIC). The '623' suffix typically denotes specific tape-and-reel packaging configurations for automated assembly processes.
