8-BIT BIDIRECTIONAL UNIVERSAL SHIFT REGISTER WITH PARALLEL I/O 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.
