Additional Details:
The HD74LS174FPEL-E typically comes in a SOP (Small Outline Package). The "FPEL" suffix indicates the specific package type and lead finish. A pull-up resistor might be needed on the clock input for proper operation if the driving signal doesn't provide a sharp rising edge. The 'E' at the end suggests environmental compliance.
It is essential to consult the datasheet for the specific propagation delays, operating voltage range, and other electrical characteristics.
