Applications
The CD74HCT75EE4 is used in digital systems requiring transparent latching of data signals, such as address latches in microprocessor bus interfaces, data buffering in industrial PLCs, and signal synchronization in test and measurement equipment. Its TTL-compatible HCT inputs make it ideal for mixed 5V TTL/CMOS logic designs where older bus standards such as ISA or parallel I/O must interface with CMOS controllers. It is also used in educational and prototyping environments where through-hole DIP packages facilitate easy breadboard assembly and circuit debugging.

Frequently Asked Questions
What type of logic device is the CD74HCT75EE4 and what is its function?
The CD74HCT75EE4 is a dual D-type transparent latch in the HCT high-speed CMOS family. It contains two independent D-latches, each with complementary Q and Q-bar outputs, allowing data to pass through when the enable input is high and latching the last input state when the enable goes low, making it useful for data bus management and address decoding.
Is the CD74HCT75EE4 compatible with TTL logic levels?
Yes, the CD74HCT75EE4 belongs to the HCT family, which features TTL-compatible input switching thresholds (approximately 1.2V). This allows it to interface directly with 5V TTL logic outputs without level-shifting, making it ideal for mixed-logic systems where older TTL devices need to drive CMOS inputs.
What package does the CD74HCT75EE4 come in and what are its pin characteristics?
The CD74HCT75EE4 is housed in a 16-pin DIP (Dual-In-Line Package) through-hole package (JESD-30 code R-PDIP-T16) with 2.54mm pin pitch, providing easy insertion into breadboards and through-hole PCBs. It has a maximum output sink current of 4mA and is rated for 50pF load capacitance per output.
What are typical applications for the CD74HCT75EE4?
The CD74HCT75EE4 is commonly used as an address or data latch in 8-bit microprocessor systems, in bus transceivers and multiplexers, in industrial control panels for signal buffering, and in test equipment for capturing and holding logic states. Its complementary outputs also make it suitable for generating non-overlapping clock or control signals.
What is the difference between the HCT and HC CMOS logic families?
The HCT family, like the CD74HCT75EE4, operates from a 5V supply and has TTL-compatible input thresholds (VIH approximately 2V, VIL approximately 0.8V), allowing direct interfacing with TTL logic. The HC family has CMOS-level input thresholds (approximately 50% of VCC) and is not directly TTL-compatible without additional level shifting, making HCT preferred for 5V mixed-logic legacy system designs.
