SN74LS294N .

The SN74LS294N is a programmable Frequency Divider/Digital Timer contains 15 flip-flops plus 29 gates on a single chip. The count modulo is under digital control of the inputs provided. Both types feature an active-low CLR\ clear input to initialize the state of all flip-flops. To facilitate the incoming inspection, test points are provided. These test points are not intended to drive system loads. Both types feature two clock inputs, either one may be used for clock gating. It can easily cascadable, giving limitless possibilities to achievable timing delays.

• Count divider chain
• Useable frequency range from DC to 30MHz
• Easily expandable
