产品概述
The CY74FCT191T is a reversible modulo-16 binary counter, featuring synchronous counting and
asynchronous presetting. The preset allows the CY74FCT191T to be used in programmable dividers. The count
enable input, terminal count output, and ripple-clock output make possible a variety of methods of implementing
multiusage counters. In the counting modes, state changes are initiated by the rising edge of the clock.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
