High-Speed Silicon-Gate CMOS
The IN74ACT299 is identical in pinout to the LS/ALS299,
HC/HCT299. The IN74ACT299 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The IN74ACT299 features 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.
