DESCRIPTION

The 74F827 and 74F828 10-Bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NOR Output Enables (OE0, OE1) for maximum control flexibility. The 74F827 and 74F828 are functionally and pin compatible to AMD AM29827 and AM29828. The 74F828 is an inverting version of 74F827. TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 74F827 6.0ns 60mA 74F828 6.0ns 55mA

For conditions shown as MIN or MAX, use the appropriate value specified under operating conditions for the applicable type. 2. All typical values are at V CC = 5V, TA = 25°C. 3. Not more than one output should be shorted at one time. For testing IOS , 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, IOS tests should be performed last.
