74ACT245PC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT245PC is an octal bidirectional transceiver featuring three-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 8 ns. The device provides 24 mA low-level output current and -24 mA high-level output current at both A and B ports. It utilizes TTL-compatible inputs and CMOS-compatible outputs. The component is housed in a DIP-20 package and functions across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package configuration as the part number indicates a DIP format, which differs from common SMD variants like TSSOP or SOIC. Confirm RoHS compliance status through official documentation, as older manufacturing runs may vary. Ensure the supplier source is authorized to guarantee authenticity, given the component's legacy status within the 74ACT logic family.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a through-hole DIP package is required for prototyping or specific board layouts. It serves as a direct functional equivalent to other 74ACT245 variants but requires attention to the physical footprint difference. Verify that the circuit design accommodates the 4.5 V to 5.5 V operating voltage range and the specific pinout of the DIP-20 enclosure.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT series of high-speed CMOS logic, offering performance comparable to Low-power Schottky TTL while maintaining CMOS power advantages. The 74ACT245 specifically addresses the need for robust bidirectional data transfer in digital systems. It shares architectural similarities with the MC74ACT245 but differs in packaging and potentially in specific ordering suffixes defined by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MC74ACT245PC and other 74ACT245 variants from onsemi. Cross-manufacturer equivalents such as those from Texas Instruments or NXP should be verified for pin compatibility and electrical parameter alignment.
