Overview
The JM54ACT245S2A-R is an octal bus transceiver manufactured by National Semiconductor. It features non-inverting bidirectional data transmission with three-state outputs. The device operates on a single 5-volt supply and includes direction control (DIR) and enable (G) inputs to manage data flow between two buses. It is housed in a 20-lead LCCC package measuring 8.89x8.89 mm.
Feature Summary
- Octal bus transceiver with non-inverting bidirectional buffers
- Three-state outputs for direct bus line driving
- Direction control input manages A-to-B or B-to-A transmission
- Enable input isolates buses when deactivated
Applications
- Asynchronous two-way communication between data buses
- Memory address driver applications
- Clock driver circuits
- Bus-oriented system interconnects
Procurement Notes
Verify the manufacturer designation as National Semiconductor, noting that the company was acquired by Texas Instruments. Confirm the specific suffix 'S2A-R' corresponds to the 20-lead LCCC package configuration. Ensure compatibility with existing radiation-hardened or military-grade specifications if required by the design environment.
Selection Notes
Select this component for applications requiring high-speed octal data transfer with precise direction control. The ACT series offers low power consumption compared to standard TTL. Verify that the 20-lead LCCC footprint matches the PCB layout requirements and that the 5V supply voltage aligns with the system logic levels.
Part Context
This part belongs to the AC/ACT family of octal bus transceivers. These devices are designed for asynchronous communication and feature three-state outputs. The ACT variant provides higher speed and lower power consumption than the standard AC series, making it suitable for demanding digital systems.
Replacement Considerations
The UT54ACTS245-UQAR is a confirmed substitute from Cobham Semiconductor Solutions. Both are octal bus transceivers with three-state outputs and similar functional characteristics. Verify package compatibility and electrical parameter alignment before substitution.
