TI SN74121D

Моностабильный45 нс4,75 В ~ 5,25 В

Overview

These multivibrators feature dual negative-transition-triggered inputs and a single positive-transition-triggered input which can be used as an inhibit input. Complementary output pulses are provided.

Jitter-free operation is maintained over the full temperature and VCC ranges for more than six decades of timing capacitance (10 pF to 10 μF) and more than one decade of timing resistance (2 k may be used. Also, the range of jitter-free output pulse widths is extended if VCC is held to 5 volts and free-air temperature is 25°C. Duty cycles as high as 90% are achieved when using maximum recommended RT. Higher duty cycles are available if a certain amount of pulse-width jitter is allowed.
