description

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.

These transceivers feature open-collector driver outputs, each with a series Schottky diode to reduce capacitive loading to the bus. By using a 2-V pullup on the bus, the output signal swing will be approximately 1 V, which reduces the power necessary to drive the bus load capacitance. The driver outputs are capable of driving an equivalent dc load of as low as 10 .

The receivers have a precision threshold set by an internal bandgap reference to give accurate input thresholds over V_CC and temperature variations.

These transceivers are compatible with Backplane Transceiver Logic (BTL^TM) technology at significantly reduced power dissipation per channel.

The SN75ALS053 is characterized for operation from 0° to 70°C.
