SN74ALVTH16245DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16245DLR is a dual 8-bit or single 16-bit non-inverting bus transceiver from Texas Instruments' ALVT series. It operates with a supply voltage range of 2.7 V to 3.6 V and features TTL/CMOS compatible inputs with LVTTL outputs. The device provides a low-level output current of 64 mA and a high-level output current of -32 mA, housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable as two independent 8-bit transceivers or one unified 16-bit transceiver for flexible data routing
• Supports direct interface between TTL/CMOS logic levels and LVTTL systems without external level shifting components
• Provides robust drive capability suitable for high-capacitance buses and demanding signal integrity requirements

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data transmission on local area networks
• Memory mapping and address/data bus expansion in embedded systems
• General-purpose bidirectional data transfer between logic subsystems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the SSOP-48 package and reel tape packaging configuration. Confirm that the ALVT logic family meets the target system's voltage and speed requirements. Ensure compatibility with existing PCB footprints designed for this specific package outline.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3 V logic interface requires strong drive strength exceeding standard CMOS capabilities. It serves as an alternative to LVTH or ABTH families depending on whether lower power consumption or higher voltage tolerance is prioritized. Evaluate propagation delay specifications against the maximum clock frequency of the application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ALVTH16245A family of bus transceivers. The ALVT series is engineered to combine the low power characteristics of advanced CMOS technology with the high drive currents typically associated with bipolar circuits. This family supports various package options including SSOP and TSSOP.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH16245ADLR: Offers similar functionality but may differ in propagation delay and drive current specifications. SN74ABTH16245DLR: Supports a wider voltage range up to 5.5 V but consumes more power. Verify pinout compatibility and electrical parameters before substitution.
