high-speed, advanced low-power Schottky de-
vice 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 VCC 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.
