74ABT126DB,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT126DB,118 is a quad buffer and line driver featuring BiCMOS technology for high-speed operation. It provides four non-inverting outputs with 3-state control managed by dedicated output enable inputs (nOE). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interfacing with TTL logic levels. It incorporates IOFF circuitry to prevent backflow current during partial power-down scenarios. The component is housed in an SO14 plastic small outline package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS technology enables high-speed performance and robust output drive capabilities.
• Integrated IOFF circuitry prevents damaging backflow currents when the device is powered down.
• Outputs enter a high-impedance OFF-state upon receiving a LOW signal on the nOE input.
• Provides latch-up protection exceeding 500 mA per JESD78 standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring isolation of powered-off buses
• Quad bus interface systems utilizing 3-state buffers
• Live insertion and extraction permitted environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the package type. The datasheet revision history indicates that the DB variant was removed from the product data sheet in version 6. Confirm current production status directly with Nexperia or authorized distributors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with strong drive capability at standard 5 V logic levels. Ensure the application environment remains within the specified -40 °C to +85 °C temperature range. Verify that the required output current does not exceed the absolute maximum ratings defined in the limiting values section.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series, which utilizes Advanced BiCMOS Technology. This family is designed for high-speed digital applications operating at 5 V. The 74ABT126 specifically functions as a quad buffer with 3-state outputs, distinguishing it from non-buffering logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT126DB variant was removed from the official product data sheet in revision 6. Consider the 74ABT126D (SO14) or 74ABT126PW (TSSOP14) as verified alternatives available in current documentation.
