Frequently Asked Questions

What is the operating voltage and output drive current of the CD74ACT245M?

The CD74ACT245M operates at a supply voltage of 5V and provides a maximum output sink current (IOL) of 24mA, making it capable of driving heavily loaded bus lines in industrial and computing applications.

What package type does the CD74ACT245M use and how many pins does it have?

The CD74ACT245M comes in a 20-pin Small Outline IC (SOIC) package, JEDEC code R-PDSO-G20. This compact surface-mount package is suited for high-density PCB designs in space-constrained applications.

What are the typical applications for the CD74ACT245M bus transceiver?

The CD74ACT245M is commonly used in microprocessor data bus buffering, memory interface circuits, I/O port expansion, and backplane bus driving. Its bidirectional 8-bit non-inverting structure with direction control makes it ideal for any application requiring controlled two-way data transfer.

Can the CD74ACT245M be used as a replacement for 74ACT245 or 74HC245 transceivers?

Yes, the CD74ACT245M is pin-compatible with standard 74ACT245 devices and is functionally similar to 74HC245 transceivers. However, the ACT family has TTL-compatible input thresholds, making it a better drop-in replacement in mixed TTL/CMOS environments compared to HC variants.
