74F827 10-bit buffer/line driver, non-inverting (3-State)
74F828 10-bit buffer/line driver, inverting (3-State)
FEA TURES
•High impedance NPN base inputs for reduced loading (20µA in
High and Low states)
•I
is 20µA vs FAST family spec of 600µA and 1000µA for
IL
AMD 29827/29828 series
•Ideal where high speed, light bus loading and increased fan-in are
required
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 (OE
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.
•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 6.0ns 60mA
74F828 6.0ns 55mA
•Outputs sink 64mA
•74F827 available in SSOP type II package
