Frequently Asked Questions
How do I cascade HEF4094B devices?
Use the two serial outputs (O and O’) to connect multiple HEF4094B devices for cascading.
When does data enter the storage register?
Data is transferred to the storage register when the strobe (STR) input is HIGH.
What signal enables the parallel output?
The data appears at the outputs whenever the output enable (EO) signal is HIGH.
Are there different physical packages available?
Yes, packages include 16-lead DIL plastic (HEF4094BP), ceramic (HEF4094BD), and SO plastic (HEF4094BT).
What determines if the clock edges are positive or negative?
Positive-going clocks allow high-speed operation, while negative-going clocks enable cascading to common bus lines.
