General Description

These 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 SNx4HCT244 devices are organized as two 4-bit buffers or drivers with separate output-enable (OE) inputs.

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

Overview

SN54HCT244, SN74HCT244 SCLS175I – MARCH 2003 – REVISED FEBRUARY 2025 SNx4HCT244 Octal Buffers and Line Drivers With 3-State Outputs.

Key Features

  • Operating voltage range of 4.5V to 5.5V.
  • High-current outputs drive up to 15 LSTTL loads.
  • Low power consumption: 80µA maximum ICC.
  • Typical tpd = 13ns.
  • ±6mA output drive at 5V.
  • Low input current of 1µA maximum.
  • Inputs are TTL-voltage compatible.
  • 3-state outputs drive bus lines and buffer memory address registers 2.
