The data on this pin is shifted into the 8-bit serial shift register. CONTROL INPUTS: Shift Clock - Shift Register Clock Input. A low-to- high transition on this input causes the data at the Serial Input pin to be shifted into the 8-bit shift register. Reset - Active-low, Asynchronous, Shift Register Reset Input. A low on this pin resets the shift register portion of this device only. The 8-bit latch is not affected. Latch Clock - Storage Latch Clock Input. A low-to- high transition on this input latches the shift register data. Output Enable - Active-Low Output Enable. A low on this input allows the data from the latches to bepresented at the outputs. A high on this input forces the outputs (QA-QH) into the high-impedance state. The serial output is not affected by this control unit. OUTPUTS: QA-QH - Noninverted, 3-state, latch outputs. SQH - Voninverted, Serial Data Output. This is the output of the eighth stage of the 8-bit shift register. This output does not have three-state capability. |
