Product Description

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
Input and output voltage ratings may be exceeded if the input and output current ratings are observed, package thermal impedance is calculated in accordance with JESD 51-7.
