General Description

The SNx4HC244 octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SNx4HC244 devices are organized as two 4bit buffers and drivers with separate output-enable (OE) inputs.

When OE is low, the device passes noninverted data from the A inputs to the Y outputs.

Overview

SN54HC244, SN74HC244 SCLS130G – DECEMBER 1982 – REVISED JANUARY 2025 SNx4HC244 Octal Buffers and Line Drivers With 3-State Outputs.

Key Features
