SN74LVCZ244ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ244ADBR is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.6V. The device accepts input voltages up to 5.5V, providing compatibility with 5V systems. It exhibits a maximum propagation delay of 5.9ns at 3.3V. The component is housed in a 20-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffer channels with three-state output control for bus-oriented applications.
• Accepts 5.5V input signals while operating from lower voltage supplies, enabling direct interface between 5V and 3.3V logic domains.
• Features low dynamic power consumption and controlled output ground bounce characteristics suitable for high-speed digital designs.

Buffers, Drivers, Receivers, Transceivers Applications

• Clock buffering and distribution in high-speed digital systems
• Bus-oriented architectures requiring signal isolation and drive capability
• Voltage translation interfaces between 5V and 3.3V logic families

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the 20-SSOP package and tape-and-reel packaging configuration. Confirm that the LVCZ series designation indicates the specific electrical characteristics regarding ground bounce and input thresholds required for your application. Ensure the manufacturer source is Texas Instruments or an authorized distributor to guarantee authenticity and datasheet compliance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5V logic inputs with 3.3V powered buses. The LVCZ variant offers optimized performance for reducing ground bounce compared to standard LVC devices. Consider the SSOP-20 package constraints for PCB layout. Verify that the 5.5V input tolerance meets the driving source voltage levels without external level shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCZ family of CMOS logic devices. It is functionally similar to the SN74LVC244A but includes specific enhancements for reduced ground bounce. It serves as an octal buffer/driver alternative to older LS or HC series parts, offering faster switching speeds and lower power consumption in modern low-voltage environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC244ADW is a pin-compatible alternative in a SOIC-20 package. The SN74LVCZ244ADW shares the same electrical specifications but differs in package type. Verify package dimensions and thermal requirements before substitution.
