Product Introduction

The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features

  • Wide supply voltage range from 2.0 to 6.0 V
  • CMOS low power dissipation

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
  • Input levels: For 74HC244: CMOS level; For 74HCT244: TTL level
  • Octal bus interface
  • Non-inverting 3-state outputs
  • Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V), JESD7A (2.0 V to 6.0 V)
  • ESD protection: HBM JESD22-A114F exceeds 2000 V, MM JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 ℃ to +85 ℃ and -40 ℃ to +125 ℃
