description

The SN74FB2032 device is a 9-bit transceiver designed to translate signals between TTL and backplane

transceiver logic (BTL) environments and to perform bus arbitration. It is designed specifically to be compatible

with IEEE Std 1194.1-1991.

The B port operates at BTL-signal levels. The open-collector B ports are specified to sink 100 mA and have

minimum output edge rates of 2 ns. Two output enables (OEB and OEB) are provided for the B outputs. When

OEB is low, OEB is high, or V

is less than 2.1 V, the B port is turned off.

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.

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.
