IDT IDT54AHCT191
The IDT54174AHCT191 is a reversible modul0-16 binary counter, featuring synchronous counting and asynchronous presetting, built using advanced CEMOS'·, a dual metal CMOS tEl6:hnology. The preset feature allows the IDT54/74AHCT191 to be used in programmable dividers. The Count Enable input, the Terminal Count output and the Ripple Clock output make possible a variety of methods of implementing multistage counters.| Part No. | IDT54AHCT191 |
