DESCRIPTION
The 74F821 series bus interface registers are designed to
eliminate the extra packages required to buffer existing registers and
provide extra data width for wider data/address paths of busses
carrying parity.
The 74F821/74F822 are buffered 10-bit wide versions of the popular
74F374/74F534 functions.
The 74F822 is the inverted output version of 74F821.
The 74F823 and 74F824 are 9-bit wide buffered registers with clock
enable (CE) and master reset (MR) which are ideal for parity bus
interfacing in high microprogrammed systems.
The 74F824 is the inverted version of 74F823.
The 74F825 and 74F826 are 8-bit buffered registers with all the
74F823/74F824 controls plus output enable (OE0, OE1, OE2) to
allow multiuser control of the interface, e.g., CS, DMA, and RD/WR.
They are ideal for uses as an output port requiring high I
OL
/I
OH
.
The 74F826 is the inverted version of 74F825.
