HD74HC299
8-bit Universal Shift/Storage Register (with 3-state outputs)
Description
The HD74HC299 features multiplexed inputs/outputs to achieve full 8-bit data handling in a single 20-pin package. Due to the large output drive capability and 3-state feature, this device is ideally suited for interfacing with bus lines in a bus oriented system. Two function select inputs and two output control inputs are used to choose the mode of operation as listed in the function table. Synchronous parallel loading is accomplished by taking both function select lines S0 and S 1 high. This places the 3-state outputs in a high impedance state, which permits data applied to the input/output lines to be clocked into the register. Reading out of the register can be done while the outputs are enabled in any mode. A direct overriding clear input is provided to clear the register whether the outputs are enabled or disabled.

Notes: 1. a to h; the level of steady-state input at inputs A through H, respectively. These data are loaded into the flip-flop outputs are isolated from the input/output terminals. 2. QA0 to Q H0; the level of QA through QH , respectively, before the indicated steady-state input conditions were established. 3. QAn to Q Hn; the level of QA through QH , respectively, before the most-recent transition of the clock. 4. = ; When one or both output controls are high the eight input/output terminals are desabled to the high-impedance state, however, sequential operation or clearing of the register is not affected. 5. When clear is low, outputs of Q A' and QH' are low, in spite of other inputs.
