SN74HCT245 (ACTIVE)

Octal Bus Transceivers With 3-State Outputs

Octal Bus Transceivers With 3-State Outputs - SN74HCT245
 

Description

The SNx4HCT245 octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

The SNx4HCT245 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 4.5 V to 5.5 V
  • High-Current 3-State Outputs Drive Bus Lines Directly or up To 15-LSTTL Loads
  • Low Power Consumption, 80-µA Maximum ICC
  • Typical tpd = 14 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Maximum
  • Inputs Are TTL-Voltage Compatible
