description

The SN74FB2031 device is a 9-bit transceiver designed to translate signals between TTL and backplane

transceiver logic (BTL) environments. It is specifically designed 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. Two output

enables(OEBandOEB) are provided for the Boutputs. WhenOEBislow, OEBishigh, orV is less than 2.1 V,

the B port is turned off.

The A port operates at TTL signal levels. The A outputs reflect the inverse of the data at the B port when the

A-port output enable (OEA) is high. When OEA is low or V

high-impedance state.

is less than 2.1 V, the A outputs are in the
