74LVC245AQG

Overview

The IDT 74LVC245AQG is an octal bus transceiver from the 74LVC series, housed in a 20-QSOP package. It features non-inverting logic with one element of eight bits per element and supports 3-state outputs. The device operates within a supply voltage range of 2.7V to 3.6V. It provides output drive currents of 24mA for both high and low states. The operating temperature range extends from -40°C to 85°C (TA). This component is classified as a buffer, driver, receiver, or transceiver IC.

Feature Summary

• Octal bus transceiver architecture providing bidirectional data transfer capabilities
• Non-inverting logic function with 3-state output control
• Compatible with 3.3V logic systems via specified voltage range

Applications

• High-speed data bus driving applications
• Clock drivers and buffered oscillators
• Memory module data line interfacing

Procurement Notes

Verify the specific manufacturer designation, as IDT was acquired by Renesas Electronics Corporation. Confirm the package type matches the required 20-QSOP form factor. Ensure the RoHS compliance status aligns with project requirements, noting that some sources indicate varying compliance levels. Check for moisture sensitivity level (MSL 3) handling constraints during assembly.

Selection Notes

Select this component when an octal, non-inverting transceiver is required for 3.3V logic interfaces. The 24mA drive capability suits moderate load conditions on data buses. The wide operating temperature range supports industrial environments. Consider the 20-QSOP package size for space-constrained PCB layouts compared to larger SOP variants.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. The 74LVC245 is a standard octal bus transceiver design widely used in digital systems. IDT, now part of Renesas, produced this variant with specific packaging and electrical characteristics tailored for 3.3V applications.

Replacement Considerations

The 74LVC245AE4Q is a documented alternative part number from the same manufacturer offering similar functional specifications.
