IDT74LVC245APGG8

Overview

The IDT74LVC245APGG8 is a 3.3V CMOS octal bus transceiver with 3-state outputs and 5-volt tolerant I/O, manufactured by Renesas Electronics Corporation under the IDT brand. It operates within an industrial temperature range of -40°C to +85°C and utilizes 0.5 micron CMOS technology. The device supports VCC levels from 2.7V to 3.6V, featuring ±24mA high output drivers for moderate to heavy loads. It provides asynchronous communication between two busses via DIR and OE control pins, ensuring rail-to-rail output swing and improved noise margins through input hysteresis.

Feature Summary

• Supports hot insertion and mixed voltage systems
• All inputs, outputs, and I/O are 5V tolerant
• High output drivers capable of driving moderate to heavy loads
• Inputs designed with hysteresis for improved noise margin

Applications

• 5V and 3.3V mixed voltage systems
• Data communication systems
• Telecommunication systems

Procurement Notes

Verify the package suffix PGG corresponds to the Green Quarter Size Small Outline Package (QSOP) as specified in the ordering information. Confirm the absence of the 'X' suffix indicates no bus-hold functionality. Ensure the component meets the industrial temperature range requirements (-40°C to +85°C) for your specific application environment before procurement.

Selection Notes

Select this component when asynchronous communication between two busses is required in mixed 3.3V/5V supply systems. The ±24mA drive capability makes it suitable for moderate to heavy loads. Consider the QSOP package dimensions if space constraints exist. Verify that the 5V tolerance on all I/O pins aligns with the interfacing logic levels in the target design.

Part Context

This part belongs to the IDT74LVC245A series of octal bus transceivers. It is part of the broader LVC family characterized by low power consumption and high-speed performance. The device is manufactured using advanced dual metal CMOS technology, offering a balance of speed and power efficiency suitable for various digital interface applications.

Replacement Considerations

Compatible substitutes include other octal bus transceivers with similar 3.3V operation, 5V tolerance, and 3-state outputs. Ensure any replacement maintains the same pinout compatibility and drive current capabilities. Verify that the alternative device supports the required industrial temperature range and package type.
