JM54ACT245BSA-R

Overview

The JM54ACT245BSA-R is a non-inverting octal bus transceiver from the 54ACT series, manufactured by National Semiconductor. It features eight bits of data transmission with three-state outputs and operates on a single 5-volt supply. The device supports bidirectional communication between data buses via direction control inputs. It is housed in a 20-lead flatpack package and is designed for asynchronous two-way data transfer applications requiring high speed and low power consumption.

Feature Summary

• Non-inverting octal bus transceiver design for asynchronous two-way communication
• Three-state outputs capable of driving bus lines directly
• Direction control input minimizes external timing requirements
• Operates on a single 5-volt supply

Applications

• Interface between various bus systems
• Memory address driver circuits
• Clock driver applications
• Bus-oriented digital logic environments

Procurement Notes

Verify the manufacturer designation as National Semiconductor or its successor Texas Instruments. Confirm the specific suffix 'BSA-R' indicates the 20-lead flatpack package and reel packaging format. Ensure the component meets the required voltage and temperature specifications for your target application environment before procurement.

Selection Notes

Select this component when an octal, non-inverting transceiver with tri-state capability is required for 5V logic systems. It is suitable for applications needing bidirectional data flow control with minimal external timing overhead. Consider the 20-lead flatpack form factor for board layout compatibility.

Part Context

This part belongs to the 54ACT series, which provides extended temperature range operation and enhanced noise immunity compared to standard commercial variants. The ACT series is widely used in digital systems requiring reliable data transmission across multiple bus lines with defined output states.

Replacement Considerations

Compatible substitutes include other 54ACT245 variants from National Semiconductor or Texas Instruments. Verify pinout compatibility and electrical characteristics such as propagation delay and output current drive strength before substitution.
