74LCX07BQX

Overview

The onsemi 74LCX07BQX is a low-voltage CMOS hex buffer manufactured with sub-micron silicon gate and double-layer metal wiring CMOS technology. It features open-drain outputs and non-inverting logic. The device operates within a supply voltage range of 2V to 5.5V. It contains six independent buffer elements, each handling one bit. The component is housed in a 14-DQFN package measuring 3x2.5 mm. It supports surface mount installation and functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides high-speed buffering capabilities suitable for low-power applications
• Features open-drain output configuration for flexible interfacing
• Includes protection circuits against static discharge for enhanced reliability

Applications

• Low-power and high-speed 3.3 V digital systems
• Interfacing between components requiring 5 V tolerant inputs
• PCI bus level signal transmission

Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any substitute components maintain pin compatibility and electrical specifications. Check for RoHS compliance and environmental export classifications. Validate lead times as stock levels may fluctuate significantly for discontinued items.

Selection Notes

Select this component when a non-inverting hex buffer with open-drain outputs is required. It is suitable for designs needing 5 V tolerant inputs while operating at lower voltages. Consider the 14-DQFN package constraints for PCB layout. Verify that the open-drain nature aligns with the pull-up requirements of the target circuit design.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as a buffer within the broader family of line drivers and receivers. The 74LCX series is designed for high-speed operation with low power consumption, bridging the performance gap between older AC/ACT families and newer LVC technologies.
