74LVT16245BEV,118

Overview

The 74LVT16245BEV,118 is a high-performance BiCMOS 16-bit bidirectional bus transceiver designed for VCC operation at 3.3 V. It features non-inverting 3-state bus-compatible outputs in both send and receive directions. The device includes an output enable input (nOE) for easy cascading and a direction input (nDIR) for direction control. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an ambient temperature range from -40 °C to +85 °C.

Feature Summary

• Features bus hold data inputs that eliminate the need for external pull-up resistors to hold unused inputs
• Provides latch-up protection exceeding 500 mA according to JESD78B Class II standards
• Offers ESD protection exceeding 2000 V under HBM conditions and 200 V under MM conditions
• Permits live insertion and extraction without causing bus current loading when tied to a 5 V bus

Applications

• High-performance 16-bit bidirectional bus interface applications
• Systems requiring TTL input and output switching levels
• Interfaces connecting systems operating at different supply voltages, such as 3.3 V and 5 V

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for designs requiring a 16-bit wide bus interface with 3-state outputs. Ensure the application environment stays within the specified -40 °C to +85 °C temperature range. Confirm that the system logic levels are compatible with the TTL input and output switching characteristics defined in the datasheet.

Part Context

This part belongs to the 74LVT16245B family of 3.3 V 16-bit transceivers. It shares functional similarities with other variants like the 74LVTH16245B but differs in package type. The BEV suffix indicates the VFBGA56 plastic very thin fine-pitch ball grid array package, which is distinct from SSOP or TSSOP options available in the same product line.

Replacement Considerations

The 74LVTH16245BEV is a functionally equivalent variant within the same family. Other packages such as SSOP48 (74LVT16245BDL) or TSSOP48 (74LVT16245BDGG) offer identical electrical performance but require footprint changes.
