74FCT16245ATPVG

Overview

The 74FCT16245ATPVG is a dual 8-bit bus transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports bidirectional data flow controlled by a single direction input. The device features three-state outputs and is housed in a 48-pin TSSOP package. It is designed for asynchronous two-way communication between data buses, ensuring reliable signal transmission across mixed-voltage systems.

Feature Summary

• Dual 8-bit architecture enabling simultaneous processing of two independent data channels
• Bidirectional data transfer capability with unified control logic
• Three-state output design allowing direct connection to system buses without external drivers

Applications

• Asynchronous two-way communication between data buses
• Mixed 3.3V and 5V supply system translation
• Memory address latch implementation
• I/O port expansion circuits

Procurement Notes

Verify the specific suffix 'ATPVG' against official Renesas documentation to confirm pinout compatibility and RoHS status. Confirm lead-free compliance and moisture sensitivity level requirements before integration. Check for active manufacturing status as older FCT series parts may have limited availability or end-of-life notices.

Selection Notes

Select this component when designing systems requiring high-speed bidirectional data transfer between 5V logic domains. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the load capacitance does not exceed specifications to maintain signal integrity at the required propagation delay speeds.

Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices. It serves as a standard interface solution for legacy and industrial applications requiring robust bus interfacing. The TSSOP-48 package provides a compact footprint suitable for dense PCB layouts while maintaining thermal performance for continuous operation.

Replacement Considerations

Direct substitutes include the SN74FCT16245ATDC from Texas Instruments. Verify pin-to-pin compatibility and electrical characteristics before substitution.
