2 / 5 page www.fairchildsemi.com 2 Unit Loading/Fan Out Functional Description The output enable (OE) is active LOW. If the device is dis- abled (OE HIGH), the outputs are in the high impedance state. The transmit/receive input (T/R) controls whether data is transmitted from the A bus to the B bus or from the B bus to the A bus. When T/R is LOW, B data is sent to the A bus. If T/R is HIGH, A data is sent to the B bus. Function Table H = HIGH Voltage Level L = LOW Voltage Level X = Don’t Care Z = High Impedance State Logic Diagram Pin Names Description U.L. Input IIH/IIL HIGH/LOW Output IOH/IOL OE Output Enable Input (Active LOW) 1.0/1.0 20 µA/−0.6 mA T/R Transmit/Receive Input 1.0/1.0 20 µA/−0.6 mA A0–A7 Side A Inputs or 3.5/0.667 70 µA/−0.4 mA 3-STATE Outputs 750/20 −15 mA/12 mA B0–B7 Side B Inputs or 3.5/0.667 70 µA/−0.4 mA 3-STATE Outputs 750/20 −15 mA/12 mA Inputs Outputs OE T/R L L Bus B data to Bus A L H Bus A data to Bus B HX Z |
