This pulse width is essentially independent of VCC and temperature variations. Jitter-free operation is maintained over the full temperature and VCC ranges for greater than six decades of timing capacitance (10 pF to 10 µF), and greater than one decade of timing resistance (2.0 to 100 kΩ for the SN74LS221).
