The SN75ALS053 is a four-channel, monolithic,

high-speed, advanced low-power Schottky de-

vice designed for two-way data communication

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 Ω.

The receivers have a precision threshold set by an internal bandgap reference to give accurate input thresholds

over V

and temperature variations.

These transceivers are compatible with Backplane Transceiver Logic (BTL ) technology at significantly

reduced power dissipation per channel.

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

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
