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_CC 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.
