DC1562B-D

DEMO MANUAL DC1562B LTC699X-X TimerBlox: Oscillators, One Shots, PWM, Delay, Power on Reset Description Demonstration circuit 1562B is an engineering tool to The center part of the board can be detached as a stream- design and evaluate the LTC699X-X family of TimerBlox lined circuit, to combine with a pre-existing circuit. For circuits. The center section of the board contains a pre- application flexibility, a provision is made for buffering and configured TimerBlox function. DC1562B comes in twelve inverting the output of the timer. An optional NC7W04P6X timing function variations as outlined in Table 1. SC70 package dual inverter can be added at U2 to provide this functionality. Surrounding the center board is a playground prototyping area. The prototyping area has pads for DIP-8, S8, MS8, Design files for this circuit board are available at or S6 packages with bread boarding connections to each DEMO MANUAL DC1562B Using Demo Boar D Table 1.
