CD74HCT243E** from **Intersil** is a high-speed CMOS **quad bus transceiver** designed for bidirectional data communication between buses operating at different voltage levels.

The CD74HCT243E from Intersil is a high-speed CMOS quad bus transceiver designed for bidirectional data communication between buses operating at different voltage levels. This integrated circuit (IC) is part of the HCT (High-Speed CMOS with TTL Compatibility) family, ensuring seamless interfacing with TTL logic levels while maintaining the low power consumption benefits of CMOS technology.

Featuring four independent bidirectional channels, the CD74HCT243E enables efficient data transfer in applications such as microprocessor systems, data routing, and bus isolation. Each channel is controlled by a direction pin, allowing flexible data flow management. With a wide operating voltage range (4.5V to 5.5V) and robust output drive capability, this component ensures reliable performance in mixed-voltage environments.

Key characteristics include high noise immunity, balanced propagation delays, and low power dissipation, making it suitable for industrial, automotive, and computing applications. The device is available in a 16-pin DIP or SOIC package, offering compatibility with standard PCB designs.

Engineers favor the CD74HCT243E for its efficiency, reliability, and ease of integration in systems requiring bidirectional level shifting or bus buffering. Its adherence to industry standards ensures long-term availability and consistent performance across diverse applications.
