Product Summary
The HEF4538BT is a dual retriggerable-resettable monostable multivibrator. The HEF4538BT has an active LOW trigger/retrigger input (nA), an active HIGH trigger/retrigger input (nB), an overriding active LOW direct reset input (nCD), an output(nQ) and its complement (nQ), and two pins (nREXT/CEXT, and nCEXT, always connected to ground) for connecting the external timing components CEXT and REXT.
Parametrics
HEF4538BT absolute maximum ratings: (1)supply voltage:-0.5V to +18 V; (2)input clamping current:±10 mA; (3)input voltage:-0.5 to VDD + 0.5 V; (4)output clamping current:±10 mA; (5)input/output current:±10 mA; (6)supply current:50 mA; (7)storage temperature:-65℃ to +150℃.
Features
