74LVT162240ADGG,11

Overview

The Nexperia 74LVT162240ADGG,11 is a high-performance BiCMOS inverting buffer/driver designed for VCC operation at 3.3 V (range 2.7 V to 3.6 V). It features sixteen 3-state outputs controlled by four active-low enable pins (1OE, 2OE, 3OE, 4OE), each managing four outputs. The device incorporates 30 Ω series resistance in pull-up and pull-down structures to reduce line noise. It supports TTL input/output switching levels and provides interface capability to systems operating at 5 V supply. The component operates within an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated 30 Ω series resistance in output structures eliminates the need for external termination resistors.
• Bus-hold data inputs maintain unused input states without requiring external pull-up resistors.
• Outputs remain in a high-impedance state during power-up to prevent bus contention.
• Provides interface compatibility with 5 V systems while operating at 3.3 V.

Applications

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

Procurement Notes

Verify that the ordering suffix matches 'DGG' for the TSSOP48 package (SOT362-1) and ',11' for the standard reel packaging configuration. Confirm the revision level corresponds to Rev. 6 or later to ensure compliance with updated ESD specifications per JEDEC standards. Ensure the application environment remains within the specified -40 °C to +85 °C operating temperature range.

Selection Notes

Select this component when designing 3.3 V bus interfaces requiring inverting logic functions with integrated termination capabilities. It is suitable for applications needing drive currents of ±12 mA and protection against live insertion or extraction events. Consider its 5 V tolerance for interfacing with legacy components. Verify that the 48-pin TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the 74LVT logic family, utilizing Advanced Low-Voltage BiCMOS Technology. It serves as a specialized variant within the 74LVT16224x series, distinguished by its inverting function and integrated series resistance. Unlike non-inverting buffers such as the 74LVT162244, it provides signal inversion alongside high-speed buffering for 3.3 V system architectures.

Replacement Considerations

The datasheet explicitly lists the type number 74LVT162240ADL (SSOP48 / SOT370-1) as removed from the product specification. No other direct substitute part numbers are documented in the provided source material.
