s Typical power dissipation 145 mW s Count frequency 42 MHz
Ordering Code:
Order Number DM7490AN Package Number N14A Package Description 14-Lead Plastic Dual-In-Line Pac.
To use the maximum count length (decade or four-bit binary), the B input is connected to the QA output. The input count.
The DM7490A monolithic counter contains four masterslave flip-flops and additional gating to provide a divide-bytwo 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 al.
