Retriggerable Monostable Multivibrators
These d-c triggered multivibrators feature output pulse width control by three methods. The
basic pulse time is programmed by selection of external resistance and capacitance values. The
‘122, ‘L122, and ‘LS122 have internal timing resistors that allow the circuits to be used with only
an external capacitor, if so desired. Once triggered, the basic pulse width may be extended by
retriggering the gated low-level-active (A) or high-level-active (B) inputs, or be reduced by use of the
overriding clear.
The ‘LS122 and ‘LS123 are provided enough Schmitt hysteresis to ensure jitter-free triggering from
the B input with transition rates as slow as 0.1 millivolt per nanosecond.
Rochester Electronics
Manufactured Components
Rochester branded components are
manufactured using either die/wafers
purchased from the original suppliers
or Rochester wafers recreated from the
original IP. All recreations are done with
the approval of the OCM.
Parts are tested using original factory
test programs or Rochester developed
test solutions to guarantee product
meets or exceeds the OCM data sheet.
