NTE74LS90 Integrated Circuit TTL- Decade Counter
14- Lead DIP
Description: The NTE74LS90 is a monolithic 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- five.
The counter has a gated zero reset and also has gated set- to- nine inputs for use in BDC nine’s plement applications.
To use the maximum count length (decade or four- bit binary), the B input is connected to the QA output. The input count pulses are applied to input A and the outputs are as described in the appropriate Function Table. A symmetrical divide- by- ten...
