74LVC162244ADGG:51

Overview

The 74LVC162244ADGG:51 is a 16-bit non-inverting buffer and line driver manufactured by Nexperia, formerly NXP Standard Products. It features four output enable inputs controlling 3-state bus-compatible outputs. The device operates with a supply voltage range of 1.2 V to 3.6 V and includes 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. Inputs are tolerant up to 5.5 V, allowing direct interfacing with 5 V logic devices.

Feature Summary

• Features integrated 30 Ω series termination resistors in output stages to minimize signal reflections and line noise.
• Provides high-impedance OFF-state when disabled, supporting mixed 3.3 V and 5 V system applications.
• Designed with low inductance multiple power and ground pins to ensure minimum noise and ground bounce.
• Inputs tolerate up to 5.5 V even when the device is powered off or disabled.

Applications

• Mixed 3.3 V and 5 V interface circuits
• High-speed data bus buffering
• Line driving for parallel communication

Procurement Notes

Verify that the ordering suffix :51 corresponds to the specific tape and reel packaging configuration required for your assembly process. Confirm the manufacturer designation as Nexperia, noting the transition from the former NXP Standard Product business. Ensure the component meets the specified temperature range and package dimensions for your design constraints.

Selection Notes

Select this component for designs requiring 16-bit buffering with controlled impedance termination. It is suitable for systems operating between 1.2 V and 3.6 V that require compatibility with 5 V input signals. Consider the TSSOP48 package availability and the specific electrical characteristics regarding propagation delay and drive strength for high-speed performance requirements.

Part Context

This part belongs to the 74LVC and 74LVCH logic families, which are CMOS-based standard logic components designed for low power consumption and wide supply voltage operation. The 162244A variant specifically addresses high-speed bus applications through its integrated termination resistors and multi-driver capability.

Replacement Considerations

The 74LVCH162244ADGG is a compatible variant within the same family offering bus hold functionality on data inputs. Verify if the absence of bus hold in the LVC version impacts your specific circuit design before substituting.
