Overview
These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the 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 discharge (DISCH) and ground. The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs.

Questions about NE555DR
What supply voltage range, output drive capability, and supply current characterize the TI NE555DR?
The Texas Instruments NE555DR is a precision bipolar timer IC that operates from a 4.5 V to 16 V supply. Its output stage is capable of sourcing or sinking up to 200 mA, making it compatible with TTL logic when operated from a 5 V supply. Typical supply current is approximately 3 mA at 5 V and 10 mA at 15 V under no-load conditions.
What package type and packaging option characterize the TI NE555DR?
The NE555DR is supplied in an 8-pin SOIC (D) surface-mount package. The "R" suffix indicates tape-and-reel packaging, with 2,500 devices per reel for automated assembly. The datasheet identifies the package type and ordering information but does not provide the SOIC package's mechanical body dimensions. Therefore, package length, width, height, and lead pitch should be obtained from the corresponding TI package drawing rather than this datasheet alone.
What timing modes and operating capabilities does the TI NE555DR support?
The NE555DR supports both monostable (one-shot) and astable (oscillator) operating modes. It can generate time delays ranging from microseconds to hours using external resistor-capacitor (RC) networks. The timing interval has a typical temperature coefficient of 50 ppm/°C, and in astable operation, both the frequency and duty cycle are determined by external resistor and capacitor values.
What operating temperature range and environmental ratings apply to the TI NE555DR?
The NE555DR is specified for operation over a 0°C to +70°C ambient temperature range. The device is available in RoHS-compliant packaging with Moisture Sensitivity Level (MSL) 1, allowing unlimited floor life under standard JEDEC conditions.
What packaging options support automated SMT assembly for the TI NE555DR?
The "R" suffix indicates 13-inch (330 mm) tape-and-reel packaging with 2,500 devices per reel, making the device suitable for automated pick-and-place assembly. The package carries an MSL 1 rating with a peak classification temperature of 260°C, in accordance with JEDEC moisture sensitivity classification.
