Frequently Asked Questions

What is the maximum operating frequency of CD74HCT112EE4 and at what supply voltage?

The CD74HCT112EE4 operates at a maximum frequency of 20 MHz when powered from a 5 V supply with a 50 pF load capacitance. This makes it suitable for moderate-speed digital logic and synchronous counter designs in 5 V systems.

How does the HCT logic family of CD74HCT112EE4 benefit mixed TTL/CMOS designs?

The HCT family operates at 5 V and accepts TTL-level input thresholds, allowing CD74HCT112EE4 to interface directly between TTL and CMOS logic without external level translators. The output sink current is 4 mA, ensuring compatibility with standard TTL loads.

Which package does CD74HCT112EE4 use and what are its physical assembly advantages?

CD74HCT112EE4 comes in a 16-pin PDIP (Dual-In-Line) package with 2.54 mm pitch, making it easy to insert into breadboards and standard DIP sockets during prototyping. Through-hole mounting provides robust mechanical strength for industrial applications.

When would you choose CD74HCT112EE4 over an edge-triggered D flip-flop in a state machine design?

CD74HCT112EE4 is preferred when independent J and K inputs are needed for conditional toggling or holding of state without external logic gates. Its negative-edge triggering and dual-element arrangement allow 2 independent state bits to be managed in a single 16-pin package at 5 V.
