74LVT16245BDGGRE4

Overview

The SN74LVT16245BDGGRE4 is a 3.3-V ABT 16-bit bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a voltage range of 2.7 V to 3.6 V and features TTL/CMOS input levels with LVTTL output levels. The device provides a low-level output current of 64 mA and a high-level output current of -32 mA, ensuring strong drive capability. It exhibits a propagation delay of 3.3 ns and functions as a non-inverting transceiver. Packaged in a 48-TVSOP, it supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission for 16-bit wide buses using a single control signal.
• Features 3-state outputs that isolate the device when disabled to prevent bus contention.
• Designed for 3.3-V ABT technology to ensure compatibility with standard logic families.

Applications

• High-density memory modules requiring 16-bit data path interfacing
• Consumer products utilizing 3.3-V logic systems
• Computing platforms needing efficient bus arbitration and data routing

Procurement Notes

Verify the specific package variant, as the BD suffix indicates a TVSOP-48 package which differs from the standard TSSOP-48 found in similar part numbers like the DGGR series. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the ordering suffix matches the required reel or cut tape specifications for your manufacturing process. Cross-reference the exact part number with the latest datasheet to confirm pinout and electrical characteristics remain unchanged.

Selection Notes

Select this component when a 3.3-V supply is available and high drive strength (64 mA) is required for long traces or heavy capacitive loads. The 3.3 ns propagation delay offers faster performance compared to standard LVTH variants. Consider the TVSOP-48 package constraints regarding thermal dissipation and board space. This part is suitable for applications where bidirectional data flow control is critical and noise immunity at 3.3 V is necessary.

Part Context

This device belongs to the SN74LVT16245 family of 16-bit bus transceivers. It utilizes Advanced BiCMOS Technology (ABT) to achieve high-speed operation while maintaining low power consumption. The family is designed for 3.3-V systems, providing a robust solution for interfacing between different logic domains within a single voltage environment.

Replacement Considerations

The SN74LVTH16245ADGGR serves as a functional alternative with similar electrical characteristics but utilizes a TSSOP-48 package instead of TVSOP-48. Verify package dimensions and pin spacing compatibility before substitution. Other family members like the SN74LVC16245 offer wider voltage ranges but may have lower drive currents.
