HC4538

Abstract: Hitachi DSA00279 /Cext pins as short as possible. 6 HD74HC4538 Circuit Operation Fig. 3 shows the HC4538 , trigger-control reset circuit is low. Trigger Operation The HC4538 is triggered by either a rising-edge signal as , initiates three events. First, the output latch goes low, thus taking the Q output of the HC4538 to a high , output of the HC4538 to a low state (19), and completing the time-out cycle. Reset Operation A low voltage applied to the Reset pin always forces the Q output of the HC4538 to a low state. 7
