9-bit Ttl/btl Address/data Transceiver

  The SN74FB2031 is a 9-bit Transceiver designed to translate signals between TTL and backplane Transceiver logic (BTL) environments. The device 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. 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. 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 VCC is less than 2.1 V, the A outputs are in the high-impedance state. Pins are allocated for the four-wire IEEE Std 1149.1 (JTAG) test bus, although currently there are no plans to release a JTAG-featured version. TMS and TCK are not connected and TDI is shorted to TDO.
