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