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.

Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last. § Per TTL-driven input (VIN = 3.4 V); all other inputs at VCC or GND ¶ This parameter is derived for use in total power-supply calculations. # IC = ICC + ∆ICC × DH × NT + ICCD (f0/2 + f1 × N1) Where: IC = Total supply current ICC = Power-supply current with CMOS input levels ∆ICC = Power-supply current for a TTL high input (VIN = 3.4 V) DH = Duty cycle for TTL inputs high NT = Number of TTL inputs at DH ICCD = Dynamic current caused by an input transition pair (HLH or LHL) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamperes and all frequencies are in megahertz. || Values for these conditions are examples of the ICC formula.
