FEATURES

74F827, 74F828

·High impedance NPN base inputs for reduced loading (20µA in
High and Low states)

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. TYPICAL PROPAGATION DELAY 6.0ns 6.0ns TYPICAL SUPPLY CURRENT (TOTAL) 60mA 55mA

·IIL is 20µA vs FAST family spec of 600µA and 1000µA for
AMD 29827/29828 series

·Ideal where high speed, light bus loading and increased fan-in are
required

·Controlled rise and fall times to minimize ground bounce ·Glitch free power-up in 3-State ·Flow through pinout architecture for microprocessor oriented
applications

TYPE 74F827 74F828

·Outputs sink 64mA ·74F827 available in SSOP type II package

NOTES: 1. 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 VCC = 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.
