Product Summary
The HEF4538BT is a dual retriggerable-resettable monostable multivibrator. Each multivibrator has an active LOW trigger/retrigger input (I0), an active HIGH trigger/retrigger input (I1), an overriding active LOW direct reset input (CD), an output (O) and its complement (O), and two pins (CTC,(1) RCTC) for connecting the external timing components Ct and Rt. Typical pulse width variation over temperature range is ± 0,2%. The applications of the HEF4538BT include Automotive and industrial.
Parametrics
HEF4538BT absolute maximum ratings: (1)supply voltage: -0.5 to +18 V; (2)input clamping current: ±10 mA at VI < -0.5 V or VI > VDD + 0.5 V; (3)input voltage: -0.5 to VDD + 0.5 V; (4)output clamping current: ±10 mA at VI < -0.5 V or VI > VDD + 0.5 V; (5)input/output current: ±10 mA; (6)supply current: 50 mA; (7)storage temperature: -65 to +150 ℃.
