Instructions for Using the CD74HC191E:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0 V to 6.0 V.
- Connect the ground (GND) pin to a stable reference potential.
Input Signals:
- Apply input signals (e.g., clock, up/down control, preset, and clear) within the specified voltage levels (VIH and VIL).
- Ensure input currents do not exceed the maximum ratings (IIH and IIL).
Output Signals:
- The output signals will be within the specified high (VOH) and low (VOL) voltage levels.
- Ensure the output current (IOH and IOL) does not exceed the maximum ratings.
Propagation Delay:
- The propagation delay time (tpd) is typically 25 ns at VCC = 4.5 V and fo = 10 MHz.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 85°C.
- Store the device within the temperature range of -65°C to 150°C.
Power Dissipation:
- Ensure the power dissipation (PD) does not exceed 100 mW to avoid overheating.
Handling Precautions:
- Handle the device with care to avoid static damage.
- Follow proper soldering techniques to prevent thermal stress.
By adhering to these parameters and instructions, you can ensure reliable operation of the CD74HC191E.
