TEXAS INSTRUMENTS SN54LS245 SN74LS245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS Manual
SN54LS245, SN74LS245 are octal bus transceivers with 3-state outputs designed by Texas Instruments. These products are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the device so that the buses are effectively isolated.
