74LVT16240ADL,112

Overview

The Nexperia 74LVT16240ADL,112 is a high-performance BiCMOS inverting 16-bit buffer/driver designed for VCC operation at 3.3 V. It features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. The device supports a supply voltage range from 2.7 V to 3.6 V and operates within an ambient temperature range of -40 °C to +85 °C. It provides an output capability of +64 mA/-32 mA and includes bus-hold data inputs to eliminate external pull-up resistors.

Feature Summary

• Features 3-state buffers with four independent output enable inputs for precise control of sixteen outputs.
• Includes bus-hold data inputs that eliminate the need for external pull-up resistors to hold unused inputs.
• Supports live insertion and extraction without causing bus current loading when outputs are tied to a 5 V bus.

Applications

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

Procurement Notes

Verify the specific package type required for your design, as the datasheet indicates the ADL suffix corresponds to the SSOP-48 package (SOT370-1). Confirm that the ordering suffix matches the exact physical footprint and pinout needed for your PCB layout. Ensure the component meets the required temperature range and electrical specifications for your application environment before finalizing procurement.

Selection Notes

Select this component when a 16-bit inverting buffer with 3-state outputs is required for 3.3 V systems. It is suitable for applications needing interface capability to 5 V systems and TTL levels. Consider the TSSOP48 package if available, or verify the SSOP-48 dimensions for the ADL variant. Ensure the design accounts for the specified output drive capabilities and propagation delays.

Part Context

This part belongs to the 74LVT logic family, which utilizes Advanced Low-Voltage BiCMOS Technology. It is designed for high-speed performance and wide supply voltage ranges typical of 3.3 V logic systems. The 74LVT16240A series provides robust driving capabilities and compatibility with various logic families, making it a versatile choice for complex digital interfaces.

Replacement Considerations

Check for equivalent parts within the 74LVT family offering similar 16-bit inverting buffer functionality. Verify package compatibility, particularly between TSSOP48 and SSOP-48 variants, as pinouts may differ. Ensure any substitute maintains the required 3-state output behavior and electrical characteristics for 3.3 V operation.
