NOTES:
1. An external timing capacitor may be connected between Cext and Rext/Cext (positive). 2. To use the internal timing resistor of the LS122, connect Rint to VCC. 3. For improved pulse width accuracy connect an external resistor between Rext/Cext and
VCC with Rint open-circuited. 4. To obtain variable pulse widths, connect an external variable resistance between Rint/Cext
and VCC.
