High-Speed CMOS Logic Dual Retriggerable
Precision Monostable Multivibrator
Features
Description
• Retriggerable/Resettable Capability
The
’HC4538
and
’HCT4538
are
dual
retriggerable/resettable monostable precision multivibrators
for fixed voltage timing applications. An external resistor
(RX) and an external capacitor (CX) control the timing and
the accuracy for the circuit. Adjustment of RX and CX
provides a wide range of output pulse widths from the Q and
Q terminals. The propagation delay from trigger input-tooutput transition and the propagation delay from reset inputto-output transition are independent of RX and CX.
• Trigger and Reset Propagation Delays Independent of
RX, CX
• Triggering from the Leading or Trailing Edge
• Q and Q Buffered Outputs Available
• Separate Resets
• Wide Range of Output Pulse Widths
Leading-edge triggering (A) and trailing edge triggering (B)
inputs are provided for triggering from either edge of the
input pulse. An unused “A” input should be tied to GND and
an unused B should be tied to VCC. On power up the IC is
reset. Unused resets and sections must be terminated. In
normal operation the circuit retriggers on the application of
each new trigger pulse. To operate in the non-triggerable
mode Q is connected to B when leading edge triggering (A)
is used or Q is connected to A when trailing edge triggering
(B) is used. The period (τ) can be calculated from τ = (0.7)
RX, CX; RMIN is 5kΩ. CMIN is 0pF.
• Schmitt Trigger Input on A and B Inputs
• Retrigger Time is Independent of CX
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs

NOTES:
1. A retriggerable one-shot multivibrator has an output pulse width which is extended one full time period (T) after application of the last
trigger pulse.
2. A non-triggerable one-shot multivibrator has a time period (T) referenced from the application of the first trigger pulse.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. Unless otherwise specified, all voltages are referenced to ground.
4. The maximum allowable values of RX and CX are a function of leakage of capacitor CX, the leakage of the ’HC4538, and leakage due to
board layout and surface resistance. Values of RX and CX should be chosen so that the maximum current into pin 2 or pin 14 is 30mA.
Susceptibility to externally induced noise signals may occur for RX > 1MΩ.
5. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES:
6. When testing IIL the Q output must be high. If Q is low (device not triggered) the pull-up P device will be ON and the low resistance path
from VDD to the test pin will cause a current far exceeding the specification.
7. For dual-supply systems theoretical worst case (VI = 2.4V, VCC = 5.5V) specification is 1.8mA.

Power-Down Mode
During a rapid power-down condition, as would occur with a
power-supply short circuit with a poorly filtered power supply,
the energy stored in CX could discharge into Pin 2 or 14. To
aviod possible device damage in this mode, when CX is ≥
0.5µF, a protection diode with a 1 ampere or higher rating
(1N5395 or equivalent) and a separate ground return for CX
should be provided as shown in Figure 12.
An alternate protection method is shown in Figure 13, where
a 51Ω current-limiting resistor is inserted in series with CX.
Note that a small pulse width decrease will occur however,
and RX must be appropriately increased to obtain the originally desired pulse width.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
