SN54HC244 Datasheet Octal Buffers And Line Drivers

Manufacturer: Texas Instruments

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

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.

Key Features

  • Wide Operating Voltage Range of 2 V to 6 V.
  • High-Current Outputs Drive Up to 15 LSTTL Loads.
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers.
  • Low Power Consumption: ICC, 80-µA (Maximum).
  • Typical tpd = 11 ns.
  • ±6-mA Output Drive at 5 V.
  • Low Input Current of 1 µA (Maximum).
  • On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing D.
