• HEF4508 DUAL 4-BIT LATCH (CD4508 PIN COMPATIBLE)

LINK TO DATASHEET

(CD4508 PIN COMPATIBLE)



The HEF4508B is a dual 4-bit latch, which consists of two


identical independent 4-bit latches with separate strobe


(ST), master reset (MR), output-enable input (EO) and


3-state outputs (O).


With the ST input in the HIGH state, the data on the D


inputs appear at the corresponding outputs provided


EO is LOW. Changing the ST input to the LOW state locks the


data into the latch. A HIGH on the reset line forces the


outputs to a LOW level regardless of the state of the ST


input. The 3-state outputs are controlled by the


output-enable input. A HIGH on EO causes the outputs to


assume a high impedance OFF-state regardless of other


input conditions. This allows the outputs to interface


directly with bus orientated systems. When EO is LOW the


contents of the latches are available at the outputs.
