74LVT16240ADGG,112

Overview

The Nexperia 74LVT16240ADGG,112 is a high-performance BiCMOS 3.3 V 16-bit inverting buffer/driver with 3-state outputs. It features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four outputs. The device supports a supply voltage range of 2.7 V to 3.6 V and input voltages up to 5.5 V. Output capability is +64 mA/-32 mA. Propagation delays are typically 1.8 ns (LOW to HIGH) and 2.0 ns (HIGH to LOW) at 3.3 V. It operates from -40 °C to +85 °C.

Feature Summary

• Four independent output enable inputs control groups of four 3-state outputs each.
• Bus-hold data inputs eliminate the need for external pull-up resistors on unused inputs.
• Power-up 3-state functionality ensures no bus current loading when tied to a 5 V bus.
• Live insertion and extraction are permitted without causing bus contention.

Applications

• Driving bus lines in 3.3 V systems
• Interface capability to systems operating at 5 V supply
• TTL input and output switching level applications

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP48 package (SOT362-1). Confirm the temperature range is -40 °C to +85 °C. Ensure the datasheet revision matches the required specifications. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component for designs requiring 16-bit inverting buffering with strong drive capability. It is suitable for mixed-voltage environments due to 5.5 V tolerant inputs. Consider the TSSOP48 package constraints and thermal requirements. Verify that the 3-state outputs meet the system's isolation needs during power-up or disable states.

Part Context

This part belongs to the 74LVT16240A family of 3.3 V logic buffers. It is designed for high-speed bus interfacing. The ADGG variant specifically denotes the TSSOP48 plastic thin shrink small outline package. It complements other LVT series devices for comprehensive system logic solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the 74LVT16240A family. Verify compatibility with existing PCB footprints and signal integrity requirements. Ensure substitute parts maintain the same 3-state behavior and voltage tolerance levels.
