SN74BCT126AD

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT126AD is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art BiCMOS design to significantly reduce quiescent current (ICCZ). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range of 0°C to 70°C. Key electrical characteristics include high-level output currents up to -15 mA and low-level output currents up to 64 mA at VCC = 4.5 V. Propagation delays are specified between 1.5 ns and 7.4 ns depending on the transition type and load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features independent line drivers with 3-state outputs that disable when the associated output-enable input is low.
• Incorporates ESD protection exceeding 2000 V per MIL-STD-883C, Method 3015.
• Designed for driving bus lines or buffering memory address registers.
