Overview
The Rochester Electronics 54ACTQ245DM/B is an octal bus transceiver belonging to the ACT logic series. It features eight-bit bidirectional data transmission with true output polarity and three-state capabilities. The device utilizes a plastic TSSOP-20 package, providing direction control for asynchronous communication between two buses. It operates within a temperature range of -40 °C to 85 °C and supports supply voltages up to 5.5 V.
Feature Summary
- Octal bus transceiver architecture supporting bidirectional data transfer
- Three-state outputs allowing direct connection to system buses
- Direction control input enabling selective data flow between A and B buses
Applications
- Asynchronous two-way communication between data buses
- Bidirectional data bus driving applications
- Memory interface circuits requiring isolation
Procurement Notes
Verify the specific manufacturing lot and date code upon receipt, as Rochester Electronics sources components from various original manufacturers. Confirm that the physical marking matches the 54ACTQ245DM/B designation exactly. Request detailed test reports or datasheets from the supplier to ensure compliance with the ACT series specifications before integration into critical systems.
Selection Notes
Select this component when designing systems requiring robust octal bus interfacing with defined directionality. The ACT series offers a balance of speed and power consumption suitable for general-purpose digital logic. Ensure the application environment remains within the specified operating temperature limits and voltage ranges to maintain signal integrity and device reliability.
Part Context
This part is distributed by Rochester Electronics, LLC, which specializes in lifecycle management for obsolete and hard-to-find semiconductors. The 54ACTQ245DM/B represents a continuation of the standard 74ACT245 functionality, often sourced from legacy production runs. It serves as a replacement for original manufacturer parts in existing designs where supply chain continuity is required.
Replacement Considerations
Direct functional equivalents include the SN74ACT245 and MC74ACT245. Verify pin compatibility and electrical characteristics against the original design specifications before substitution.
