Datasheet
Octal Buffer and Line Driver With 3-State Outputs datasheet (Rev. A)
 

Description

This octal buffer and line 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 SN74HC244 is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.

Features

  • Qualified for Automotive Applications
  • ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0)
  • 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, 80-µA Max ICC
  • Typical tpd = 11 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
