National Semiconductor 5490

The input count pulses are applied to input A and the outputs are as described in the appropriate truth table A symmetrical divide-by-ten count can be obtained from the 90A counters by connecting the QD output to the A input and applying the input count to the B input which gives a divide-by-ten square wave at output QA Features Y Typical power dissipation 90A 145 mW 93A 130 mW Y Count frequency 42 MHz Connection Diagrams Dual-In-Line Package TL F 6533 – 1 Order Number DM5490J DM5490W or DM7490AN See NS Package Number J14A N14A or W14B Dual-In-Line Package Order Number DM7493AN See NS Package...
