Nat Semi DM74LS245N Octal Bus Transceivers with Tri-State Outputs DIL20

Manufactured by National Semiconductor

DIL20 through hole package

• 3-State Outputs Drive Bus Lines Directly
• PNP Inputs Reduce dc Loading on BusLines
• Hysteresis at Bus Inputs Improves Noise Margins
• Typical Propagation Delay Times Port to Port, 8 ns

DESCRIPTION

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 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.
