description
The SN55ALS160 and SN75ALS160 eightchannel general-purpose interface bus
transceivers are monolithic, high-speed,
advanced low-power Schottky (ALS) devices
designed for two-way data communications over
single-ended transmission lines. They are

Standard 488-1978. The transceivers feature
driver outputs that can be operated in either the

passive-pullup or 3-state mode. If talk enable (TE) is high, these ports have the characteristics of passive-pullup
outputs when pullup enable (PE) is low and of 3-state outputs when PE is high. T aking TE low places these ports
in the high-impedance state. The driver outputs are designed to handle loads up to 48 mA of sink current.
An active turn-off feature has been incorporated into the bus-terminating resistors so that the device exhibits
a high impedance to the bus when V
= 0. When combined with the SN55ALS161, SN75ALS161, or
CC
SN75ALS162 bus management transceiver , the pair provides the complete 16-wire interface for the IEEE-488
bus.
The SN55ALS160 is characterized for operation from –55°C to 125°C. The SN75ALS160 is characterized for
operation from 0°C 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.
†
The transceivers are suitable for IEEE Standard 896 applications to the extent of the operating conditions and characteristics specified in this
data sheet. Certain limits contained in the IEEE specification are not met or cannot be tested over the entire military temperature range.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
