HEF4538B
Dual precision monostable multivibrator
Rev. 06 -- 2 November 2009 Product data sheet
1. General description
The HEF4538B 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 10 s to infinity. The duration and accuracy of the output pulse are determined by the external timing components CEXT and REXT. The output pulse width (tW) is equal to REXT x CEXT. The linear design techniques in LOCMOS (Local Oxide CMOS) guarantee precise control of the output pulse width. A LOW level at nCD terminates the output pulse immediately. The trigger inputs' Schmitt trigger action makes the circuit highly tolerant of slower rise and fall times. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the industrial (-40 C to +85 C) and automotive (-40 C to +125 C) temperature ranges.

The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF). The maximum permissible resistance REXT, which holds the specified accuracy of tW (nQ, nQ output), depends on the leakage current of the capacitor CEXT and the leakage of the HEF4538B.
