Texas Instruments SN74HCT245 Octal Bus Transceivers

Texas Instruments SN74HCT245 Octal Bus Transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The Texas Instruments SN74HCT245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

Features

  • Operating voltage range of 4.5V to 5.5V
  • High-current 3-state outputs drive bus lines directly or up to 15-LSTTL loads
  • 80µA (maximum) ICC low power consumption
  • Typical tpd = 14ns
  • ±6mA output drive at 5V
  • A low input current of 1µA maximum
  • Inputs are TTL-voltage compatible

Applications

  • Factory automation and control
  • Grid infrastructure
  • Electronic point of sale
  • Multi-function printers
  • Motor drives
  • Storage
  • Telecom infrastructure
