The 74HC4538D,653 from Nexperia is a dual, retriggerable, precision monostable multivibrator IC. Each multivibrator section can be triggered by either the positive or negative edge of an input pulse, offering flexibility in design. The output pulse width is precisely controlled 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 2.0V to 6.0V and features a typical quiescent current of 5.2mA. It is specified for operation across an extended temperature range of -40°C to +125°C. The 74HC4538D,653 includes separate reset inputs for immediate termination of the output pulse. Schmitt-trigger action on the trigger inputs provides tolerance to slower input rise and fall times.
Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount package, this component is suitable for various electronic designs requiring precise pulse generation. Its robust design and wide operating parameters make it a reliable choice for applications needing accurate timing.
Key electrical characteristics include a propagation delay of 25 ns and two independent circuits per device. The device is designed with CMOS low power dissipation and high noise immunity, typical of HC logic families. Inputs include clamp diodes, allowing the use of current-limiting resistors for interfacing to voltages exceeding VCC.
