DESCRIPTION/ORDERING INFORMATION
These devices provide two independent timing circuits of the NA555, NE555, SA555, or SE555 type in each
package. These circuits can be operated in the astable or the monostable mode with external resistor-capacitor
(RC) timing control. The basic timing provided by the RC time constant can be controlled actively by modulating
the bias of the control-voltage input.
The threshold (THRES) and trigger (TRIG) levels normally are two-thirds and one-third, respectively, of VCC
.
These levels can be altered by using the control voltage (CONT) terminal. When the trigger input falls below
trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the
threshold input is above the threshold level, the flip-flop is reset, and the output is low. The reset (RESET) input
can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop
is reset and the output goes low. When the output is low, a low-impedance path is provided between the
discharge (DISCH) terminal and ground (GND).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.
(5) Maximum power dissipation is a function of TJ(max), θJC, and TC. The maximum allowable power dissipation at any allowable case
temperature is PD = (TJ(max) – TC)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
(6) The package thermal impedance is calculated in accordance with MIL-STD-883.

(1) This parameter influences the maximum value of the timing resistors R and RB in the circuit of Figure 1. For example, when VCC = 5 V,
the maximum value is R = RA + RB ≈ 3.4 MΩ, and for VCC = 15 V, the maximum value is ≈ 10 MΩ.

(1) 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), 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)
