SN64BCT126AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN64BCT126AN is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It belongs to the BCT logic series and features non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a typical operating current of 49 uA. It supports low-level output currents up to 64 mA and high-level output currents of -15 mA. Designed for surface mount or through-hole applications, it is housed in a PDIP-14 package and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels with 3-state output control
• Utilizes BCT logic technology for improved performance over standard TTL equivalents
• Supports bidirectional data transmission between buses with low power consumption

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffered clock signals
• Bidirectional bus transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' corresponds to the PDIP-14 package when ordering. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the supplier provides valid traceability for industrial temperature grade components. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad non-inverting buffer with 3-state capability is required. It serves as a direct replacement for older 74S126 devices with enhanced speed and lower power. Consider the PDIP-14 package constraint for PCB layout. Verify that the 5V logic level compatibility meets system requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SNx4BCT126 family of quadruple bus buffers. It shares functional similarities with the SN64BCT125 but differs in pinout and internal configuration. The BCT series represents a transition technology combining BiCMOS speed with CMOS power efficiency. It is widely used in legacy systems upgrading from standard TTL logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN64BCT126AD is a compatible alternative offering the same logical function in an SOIC-14 package. Designers must account for package footprint differences during substitution. Electrical characteristics remain consistent across these package variants.
