74ABT126D,602

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT126D,602 is a quad buffer and line driver manufactured by Nexperia. It features BiCMOS technology providing high speed and output drive capabilities within a supply voltage range of 4.5 V to 5.5 V. The device includes four independent 3-state outputs controlled by separate enable inputs (nOE). It supports partial power-down applications through integrated IOFF circuitry, which disables outputs to prevent backflow current when the device is unpowered. The component operates reliably across an ambient temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Quad bus interface with three-state buffers
• IOFF circuitry for partial power-down mode operation
• Live insertion and extraction permitted
• Direct interface with TTL levels

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the specific package variant required. Confirm the manufacturer designation aligns with current corporate branding as Nexperia acquired the legacy business. Ensure the component meets the specified RoHS compliance standards for the intended manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with isolated control over individual channels. The BiCMOS technology ensures low static power dissipation while maintaining high output drive capability. Verify that the system voltage remains within the 4.5 V to 5.5 V operating range to ensure proper logic level interfacing.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. It serves as a specialized buffer solution within the broader family of standard logic components. The device provides a robust interface between different logic domains or drives long bus lines in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT126PW is a compatible alternative featuring a TSSOP14 package instead of the SO14 package used by the 74ABT126D,602.
