Automotive Catalog Octal Buffers/Drivers With 3-State Outputs - SN74AHCT244Q


This octal buffer/driver is designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SN74AHCT244Q is organized as two 4-bit buffers/line drivers with separate output-enable (OE)\ inputs. When (OE)\ is low, the device passes data from the A inputs to the Y outputs. When (OE)\ is high, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, (OE)\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.


  • Q Devices Meet Automotive Performance Requirements
  • Customer-Specific Configuration Control Can Be Supported Along with Major-Change Approval
  • EPIC™ (Enhanced-Performance Implanted CMOS) Process
  • Inputs Are TTL-Voltage Compatible
  • Latch-Up Performance Exceeds 250 mA Per JESD 17

EPIC is a trademark of Texas Instruments.
