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 Ordering Information • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V PART NUMBER TEMP.

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.

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.

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. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), 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. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. 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.
