The IN74HC299 is identical in pinout to the LS/ALS299. The
device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL outputs.
The IN74HC299features a multiplexed parallel input/output
data port to achieve full 8-bit handling in a 20 pin package. Due
to the large output drive capability and the 3-state feature, this
device is ideally suited for interface with bus lines in a bus-
oriented system.
Two Mode-Select inputs and two Output Enable inputs are
used to choose the mode of operation as listed in the Function
Table. Synchronous parallel loading is accomplished by taking
both Mode-Select lines, S
1
and S
2
, high. This places the outputs
in the high-impedance state, which permits data applied to the
data port to be clocked into the register. Reading out of the
register can be accomplished when the outputs are enabled. The
active-low asynchronous Reset overrides all other inputs.
Outputs Directly Interface to CMOS, NMOS, and TTL
