National Semiconductor 7493

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 ’LS90 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 45 mW Y Count frequency 42 MHz Connection Diagrams (Dual-In-Line Packages) TL F 6381 – 1 Order Number DM74LS90M or DM74LS90N See NS Package Number M14A or N14A TL F 6381 – 2 Order Number DM74LS93M or DM74LS93N See NS Package Number M14A...
