The HEF4538BT is a dual retriggerable-resettable Monostable Multivibrator. Each multivibrator 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. Typical pulse width variation over the specified temperature range is ±0.2%. The multivibrator may be triggered by either the positive or the negative edges of the input pulse and will produce an accurate output pulse with a pulse width range of 10µs to infinity. The duration and accuracy of the output pulse are determined by the external timing components CEXT and REXT.
● Tolerant of slow trigger rise and fall times
● Fully static operation
● Standardized symmetrical output characteristics
● 50mA supply current
● Complies with JEDEC standard JESD 13-B
