The 74HC4538D,653 is a dual retriggerable-resettable monostable multivibrator from NXP Semiconductors. Each multivibrator features trigger/retrigger inputs, a direct reset input, and complementary outputs. The output pulse width is precisely determined by external timing components REXT and CEXT, with the formula TW = 0.7 × REXT × CEXT.
This device operates over a wide supply voltage range of 2.0 V to 6.0 V and maintains a typical pulse width variation of ±0.2% over its specified temperature range of -40 °C to +125 °C. The Schmitt-trigger action on the input makes it tolerant to slower rise and fall times, enhancing noise immunity. Inputs include clamp diodes, allowing the use of current-limiting resistors for interfacing with voltages exceeding VCC.
The 74HC4538D,653 is available in a 16-lead SOIC package (SO16). Its design is suitable for applications requiring precise timing and pulse generation where reliability and tolerance to varying input signal conditions are important.
