TEXAS INSTRUMENTS LS 245 - Transceiver, Octal, 4.75 ... 5.25 V, DIP-20

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 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 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.
