The B port outputs are capable of sinking 64mA and sourcing 15mA, as [8] 13] Bs producing very good capacitive drive characteristics. The device a7 [9] 12] Be features an Output Enable (OE) input for easy cascading and ano [70 77) a7 Transmit/Receive (T/R) input for direction control. The 3-State outputs, BO-B7, have been designed to prevent output bus loading if sFoo19s the power is removed from the device.

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at Voc = 5V, Tamb = 25C. 3. Not more than one output should be shorted at a time. For testing log, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, log tests should be performed last.
