SN74LVCZ244ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ244ANSR 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 while operating at lower logic levels. At a supply voltage of 3.3V, the maximum propagation delay (tpd) is specified as 5.9ns. The component is housed in a 20-pin SOIC 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, enabling direct interfacing between 5V and 3.3V logic domains.
• Operates reliably within a 2.7V to 3.6V power supply range.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory module address and data bus drivers
• Clock distribution circuits
• Bidirectional bus transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 20-SOIC package dimensions match the target PCB footprint. Ensure the 5.5V tolerant input specification aligns with the source logic voltage levels in the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed buffering with mixed-voltage interface capabilities. The LVCZ series offers improved performance over standard LVC devices, particularly regarding ground bounce reduction. Consider the 5.5V input tolerance if the driving circuit operates at 5V while the load requires 3.3V logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCZ244A family of octal buffers and drivers. The 'Z' variant typically denotes enhanced electrical characteristics compared to the standard LVC version, such as reduced output ground bounce. It serves as a critical interface component in digital systems requiring signal isolation or level shifting between different voltage domains.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC244A is a related variant but lacks the specific Z-series enhancements. Verify functional equivalence regarding propagation delay and ground bounce specifications before substitution. Ensure the replacement part maintains the same 20-pin SOIC package and pinout configuration.
