Frequently Asked Questions
What is the CD74ACT164EG4 and what are its key electrical specifications?
The CD74ACT164EG4 is an 8-stage serial-in parallel-out shift register from Texas Instruments operating at 5V. It belongs to the ACT logic family, which features TTL-compatible inputs and CMOS outputs. The 14-pin PDIP package suits through-hole PCB assembly, and it supports high-speed clocking for serial-to-parallel data conversion in digital systems.
What applications is the CD74ACT164EG4 designed for?
The CD74ACT164EG4 is ideal for applications requiring serial-to-parallel data conversion, such as driving LED or LCD displays, expanding I/O in embedded systems, and interfacing with serial communication buses like SPI. Its ACT logic family compatibility and 5V operation make it broadly applicable in consumer electronics, industrial controllers, and test equipment.
What package does the CD74ACT164EG4 come in, and how many pins does it have?
The CD74ACT164EG4 uses a 14-pin PDIP (Plastic Dual In-Line Package), which is a through-hole package well-suited for prototyping, socketed designs, and applications where hand soldering or DIP socket insertion is preferred. The 14-pin configuration provides 8 parallel output lines plus clock, data, reset, and power pins.
Is the CD74ACT164EG4 compatible with both TTL and CMOS logic families?
Yes, the CD74ACT164EG4 belongs to the ACT (Advanced CMOS with TTL inputs) logic family, which accepts standard TTL input voltage levels while providing CMOS output swing. This dual compatibility allows it to interface directly with 5V TTL devices such as older microprocessors and with CMOS logic ICs without requiring additional level-shifting components.
