description
The SN74FB2040 is an 8-bit transceiver designed to translate signals between TTL and backplane transceiver
logic (BTL) environments.
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 high and OEB is low, the B port is active
and reflects the inverse of the data present at the A-input pins. When OEB is low, OEB is high, or V
CC
is less
than 2.1 V, the B port is turned off.
The A port operates at TTL-signal levels and has separate input and output pins. 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 when V
CC
is less than 2.1 V, the A outputs are in the high-impedance state.
The pins TMS, TCK, TDI, and TDO are nonfunctional, i.e., not intended for use with the IEEE Std 1149.1 (JTAG)
test bus. TMS and TCK are not connected, and TDI is shorted to TDO.
BIAS V
CC
establishes a voltage between 1.62 V and 2.1 V on the BTL outputs when V
CC
is not connected.
