SL74HC299 8-Bit Bidirectional Universal Shift Register with Parallel I/O High-Performance Silicon-Gate CMOS The SL74HC299 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 SL74HC299 features a multiplexed parallel input/output data port.
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 ModeSelect lines, S 1 and S 2, high. This places the outputs in the highimpedance state, which permits data applied to the data port to be clocked into the register..
