74LVT162240ADGG:51

Overview

The 74LVT162240ADGG:51 is a 3.3 V LVT 16-bit inverting buffer/driver with 3-State outputs, manufactured by Nexperia (formerly NXP). It features four output enables controlling four groups of four outputs each. The device includes integrated 30 Ω series resistance in pull-up and pull-down structures to reduce line noise. It operates within a supply voltage range of 2.7 V to 3.6 V and supports TTL input/output switching levels. The package is a 48-pin Plastic TSSOP Type II (SOT362-1), suitable for surface mount applications.

Feature Summary

• Integrated 30 Ω series resistance in output structures eliminates the need for external termination resistors.
• Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs.
• Outputs are designed to interface directly with systems operating at a 5 V supply.
• Power-up state ensures outputs default to 3-State to prevent bus contention.

Applications

• Memory address drivers
• Clock drivers
• Bus receivers/transmitters

Procurement Notes

Verify that the ordering suffix ':51' corresponds to the specific tape and reel packaging configuration required for your assembly line. Confirm the manufacturer designation as Nexperia, noting the transition from the former NXP Standard Product business. Ensure compatibility with the 48-pin TSSOP footprint during PCB layout review.

Selection Notes

Select this component when driving 16-bit buses requiring inverting logic and 3-State control. The internal 30 Ω resistance makes it suitable for high-speed applications where signal integrity is critical without adding external components. Verify that the 3.3 V supply voltage aligns with the system architecture and that the -40 °C to +85 °C temperature range meets environmental requirements.

Part Context

This device belongs to the 74LVT family of high-performance BiCMOS products designed specifically for 3.3 V operation. It serves as a direct replacement for the 74LVT16240A-1, reflecting updated industry naming standards while maintaining identical functionality. The part is widely used in digital logic circuits requiring robust bus interfacing capabilities.

Replacement Considerations

The datasheet explicitly states that this part is functionally identical to the 74LVT16240A-1. Designers replacing older inventory should verify that the pinout and electrical characteristics remain consistent with the original design specifications.

FAQ

Does the 74LVT162240ADGG:51 require external termination resistors?

No, the device includes integrated 30 Ω series resistance in both pull-up and pull-down output structures, making external termination resistors unnecessary.

How does the device handle unused inputs?

The device features bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs in a defined state.
