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

ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
