Part Number : SN74AS245
Function : OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS
Manufacturers : Texas Instruments
4.5-V to 5.5-V Vcc Operation
Max Tpd of 5.5 ns at 5 V
3-State Outputs Drive Bus Lines Directly
pnp Inputs Reduce dc Loading
These octal bus transceivers 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 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.
The -1 version of the SN74ALS245A is identical to the standard version, except that the recommended
maximum Iol is increased to 48 mA. There is no -1 version of the SN54ALS245A.
