Part Number: SN74AS245
Function: OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS
Package: DIP, SOIC, SOP 20 Pin Type
Manufacturer: Texas Instruments
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 SN74ALS245 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.
1. 4.5-V to 5.5-V Vcc Operation
2. Max Tpd of 5.5 ns at 5 V
3. 3-State Outputs Drive Bus Lines Directly
4. pnp Inputs Reduce dc Loading
