Frequently Asked Questions
How does CD74HC107E's negative-edge triggering affect its use in a divide-by-2 frequency counter?
CD74HC107E clocks its J-K flip-flops on the falling edge of the clock signal. When wired in toggle mode with J and K tied high, each falling edge advances the output, dividing the input frequency by 2. Two cascaded CD74HC107E devices produce a divide-by-4 chain supporting input frequencies up to 20 MHz.
What supply voltage range does CD74HC107E support, and can it interface directly with 3.3 V microcontrollers?
CD74HC107E operates from 2 V to 6 V, fully compatible with 3.3 V and 5 V systems. When powered from 3.3 V, it accepts CMOS-level inputs above 2.31 V as logic high, allowing direct connection to most 3.3 V microcontrollers without level-shifting resistors or buffers.
For a through-hole prototype board, what advantages does the DIP-14 package of CD74HC107E offer versus an SOIC variant?
The DIP-14 package has 2.54 mm pin pitch, fitting standard breadboards and perforated prototype boards without adapters. Pin spacing allows manual soldering with a standard 0.8 mm tip, and the 14-pin body is large enough to read markings without magnification, reducing assembly time during lab prototyping by roughly 50% compared to SOIC-14 hand soldering.
