The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. As a result of the high input impedance, this device supports smaller timing capacitors than capacitors used by the NE555 . Thus, more accurate time delaysand oscillations are possible. Power consumption is low across the full power-supply voltage range.  \nLike the NE555, the TLC555-Q1 has a trigger level equal to approximately one-third of the supply voltage, and a threshold level equal to approximately twothirds of the supply voltage. These levels can be altered by using the control voltage pin (CONT) . When the trigger input (TRIG) falls below the trigger level, the flip-flop is set, and the output goes high. If TRIG is greater than the trigger level and the threshold input (THRES) is greater than the threshold level, the flip-flop is reset and the output goes low. The reset input (RESET) can override all other inputsand is used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output goes low. Whenever the output is low, a low-impedance pathis provided between the discharge pin (DISCH) and GND. Tie all unused inputs to an appropriate logic level to prevent false triggering.  \nPackage Information  \n\n| PART NUMBER | PACKAGE(1) | PACKAGE SIZE(2) |\n| --- | --- | --- |\n| TLC555-Q1 | SOIC (8) | 4.9mm × 6.0mm |\n\n(1) For more information, see Section 10.  \n(2) The package size (length × width) is a nominal value and includes pins, where applicable.  \nPulse Width Modulator Waveform: Top Waveform-Modulation Bottom Waveform-Output Voltage  \nAn IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
