Additional Details:

The 74HC123A integrates two independent monostable multivibrators, each triggered by either a positive-going or negative-going transition. The device features a clear input that, when low, resets the timing cycle. The output pulse width is determined by the external timing components RX and CX. The device is available in various packages, including DIP and SOIC. The recommended operating temperature range is -40°C to +85°C.
