74LVQ245SCX

Overview

The 74LVQ245SCX is a non-inverting bus transceiver manufactured by Fairchild Semiconductor, now part of onsemi. It features one element with eight bits per element and provides three-state outputs. The device operates within a supply voltage range of 2V to 3.6V and supports an operating temperature range of -40°C to 85°C (TA). It is housed in a 20-SOIC package with a width of 7.50mm. The component is RoHS compliant and lead-free.

Feature Summary

• Non-inverting logic function for bidirectional data transmission
• Three-state output capability for bus line isolation
• CMOS construction ensuring low power consumption

Applications

• Bidirectional data bus systems
• Memory interface circuits
• General-purpose digital signal routing

Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor's logic division was acquired by onsemi. Ensure the specific suffix matches the required package type and compliance standards. Confirm product status, as some listings may indicate obsolete or end-of-life status depending on the distributor source.

Selection Notes

Select this component when a single 8-bit non-inverting transceiver is required for low-voltage applications. The 2V to 3.6V supply range makes it suitable for modern digital systems. The SOIC-20 package offers surface-mount convenience. Verify that the three-state outputs meet the specific bus driving requirements of the target design.

Part Context

This part belongs to the 74LVQ series of CMOS logic devices. The LVQ series is designed for low-voltage operation, bridging the gap between older 5V logic and newer 3.3V or lower voltage standards. The 245 variant specifically denotes a wide bus transceiver configuration.

Replacement Considerations

Check for equivalents from onsemi under the same 74LVQ245 naming convention. Other manufacturers offering 8-bit non-inverting transceivers in SOIC-20 packages with similar voltage ranges may serve as functional substitutes if pin compatibility is confirmed.
