74LVT162240ADGG:11

Overview

The Nexperia 74LVT162240ADGG:11 is a high-performance BiCMOS 3.3 V 16-bit inverting buffer/driver with 3-state outputs. It features four output enable pins (1OE, 2OE, 3OE, 4OE) and includes integrated 30 Ω series termination resistors to reduce line noise. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports input voltages up to 5.5 V. It provides an output capability of +12 mA/-12 mA and functions reliably across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated 30 Ω series resistance in pull-up and pull-down structures eliminates the need for external termination resistors.
• Bus-hold data inputs maintain unused inputs at valid logic levels without requiring external pull-up resistors.
• Power-up 3-state functionality ensures no bus current loading when the output is tied to a 5 V bus.
• Input and output interface capability allows compatibility with systems operating at a 5 V supply.

Applications

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

Procurement Notes

Verify the specific ordering suffix ':11' corresponds to the TSSOP48 plastic thin shrink small outline package (SOT362-1). Confirm that the required temperature range matches the standard -40 °C to +85 °C specification. Ensure design requirements align with the 3.3 V BiCMOS technology and TTL switching levels provided in the datasheet.

Selection Notes

Select this component for applications requiring 16-bit bus interfacing with built-in termination to minimize signal reflections. It is suitable for driving bus lines where live insertion or extraction is permitted. Consider its 5 V tolerant I/O capabilities if interfacing between 3.3 V and 5 V domains is necessary.

Part Context

This part belongs to the 74LVT162240A family of 3.3 V logic buffers. It is manufactured by Nexperia USA Inc. and utilizes a 48-lead TSSOP package. The device is designed as a high-performance BiCMOS product specifically optimized for 3.3 V operation while maintaining compatibility with legacy 5 V system interfaces.

Replacement Considerations

Check for direct substitutes within the 74LVT162240A family that may offer different packaging options, such as SSOP variants, if board space constraints differ. Verify functional equivalence regarding the 30 Ω internal termination and 3-state control logic before substitution.

FAQ

Does the 74LVT162240ADGG:11 require external termination resistors?

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

How does the device handle unused inputs?

The device incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs at a valid logic level.
