74LVCR162245ZQLR

Overview

The SN74LVCR162245ZQLR is a Texas Instruments 16-bit bus transceiver featuring three-state outputs, designed for asynchronous communication between data buses. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 48-pin VQFN package with dimensions of 7x7 mm. Key electrical characteristics include a maximum propagation delay of 8.5 ns and low power consumption with a maximum quiescent current of 20 µA. It provides 12 mA output drive capability in both directions.

Feature Summary

• Designed specifically for asynchronous communication between data buses
• Features configurable voltage translation capabilities for mixed-voltage systems
• Provides bidirectional data transfer with three-state outputs

Applications

• Asynchronous communication between data buses
• Mixed-voltage system interfacing
• High-density memory modules

Procurement Notes

Verify the specific suffix ZQLR against the manufacturer's official datasheet to confirm the exact pinout, thermal pad configuration, and moisture sensitivity level. Ensure the ordering part number matches the required tape-and-reel quantity and package variant. Cross-reference the RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 16-bit wide asynchronous data transfers between different voltage domains. It is suitable for applications needing low propagation delay and high noise immunity. Consider the VQFN-48 package constraints regarding thermal dissipation and PCB layout space. Verify that the system voltage requirements align with the 2.7 V to 3.6 V operating range.

Part Context

This device belongs to the SN74LVCR162245 family of bus transceivers from Texas Instruments. It is part of the LVCR series, which focuses on low-power CMOS technology optimized for high-speed data transmission. The family shares common functional characteristics but varies in packaging options such as SSOP, TSSOP, and VQFN to suit different board density and thermal management needs.

Replacement Considerations

Compatible substitutes include SN74LVCR162245DGGR (TSSOP-48) and SN74LVCR162245DLG4 (SSOP-48). These alternatives offer identical logical functionality but differ in physical package dimensions and pin configurations. Verify mechanical fit and soldering compatibility before substitution.
