The SN75ALS053 is a four-channel, monolithic, high-speed, advanced low-power Schottky device designed for two-way data communication in a densely populated backplane. The SN75ALS053 has independent driver input (Dn) and receiver output (Rn) pins and separate driver and receiver disables. This transceiver is designed for use in high-speed bus systems and is similar to the SN75ALS057 transceiver except that the trapezoidal feature has been eliminated to speed up the propagation delays.
