74LVC162245ADGG:51

Overview

The 74LVC162245ADGG:51 is a 16-bit bus transceiver manufactured by Nexperia, formerly NXP. It features non-inverting 3-state outputs and operates within a supply voltage range of 1.2 V to 3.6 V. The device supports 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V logic systems. It includes integrated 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. The component utilizes a TSSOP48 package (SOT362-1) and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerance on inputs and outputs for safe interfacing with 5 V logic devices.
• Integrates 30 Ω series termination resistors in output stages to minimize signal reflections and line noise.
• Features low inductance multiple power and ground pins designed to reduce electromagnetic noise and ground bounce.
• Supports cascading configurations through dedicated direction control and output enable inputs.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments.
• High-speed data transmission buses requiring controlled impedance termination.
• System architectures utilizing cascaded bus structures for expanded I/O capabilities.

Procurement Notes

Verify the specific ordering suffix ':51' against official Nexperia documentation to confirm packaging details such as reel size or tape width. Ensure the procurement channel sources authentic components directly from authorized distributors to guarantee compliance with JEDEC standards and RoHS directives. Confirm that the temperature grade matches the required operational environment specifications.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 16-bit buses with mixed voltage domains. The integrated termination resistors make it suitable for high-speed applications where signal integrity is critical without external components. Consider the TSSOP48 package constraints regarding board space and thermal dissipation requirements during layout planning.

Part Context

This device belongs to the 74LVC family of CMOS logic ICs, which are optimized for low-voltage operation while maintaining compatibility with TTL levels. The 'A' suffix typically denotes an advanced version with improved electrical characteristics compared to standard variants. The product line is widely used in computing, industrial, and consumer electronics for efficient data routing.

Replacement Considerations

The 74LVCH162245ADGG serves as a functional alternative within the same family, offering identical pinout and electrical performance but including bus hold functionality on all data inputs. Verify if the absence of bus hold in the 74LVC variant impacts the specific application design before substitution.
