SN74LS245N

The SN74LS245N is an Octal Bus Transceiver IC, designed for asynchronous 2-way communication between data buses. The control-function implementation minimizes external timing requirements. The device allows 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.

• 3-state Outputs Drive Bus Lines Directly
• PNP Inputs Reduce DC Loading on Bus Lines
• Hysteresis at Bus Inputs Improves Noise Margins
• Typical Propagation Delay Times Port to Port, 8ns
• Pb-free product
