Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE7493A is a monolithic 4-bit binary counter in a 14-lead DIP-type package that contains four master-slave flip-flops and additional gating to provide a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-eight. The counter also contains a gated zero reset. To use the maximum count length of this device, the CKB input is connected to the QA output. The input count pulses are applied to CKA input and the outputs are as described in the function tables.
