SN74LVTH245APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH245APWR is a 3.3-V ABT octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports TTL/CMOS input levels while providing LVTTL output levels. The device features non-inverting logic, eight channels, and a maximum propagation delay of 2.3 ns at 3.3 V. It offers high drive capabilities with low-level output currents up to 64 mA and high-level output currents up to -32 mA. Designed for surface-mount installation, it is housed in a TSSOP-20 package and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission between two buses using direction control inputs
• Features three-state outputs that effectively isolate the bus when disabled
• Supports mixed-mode operation allowing different voltage standards on A and B ports

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous bidirectional communication between data buses
• Memory and flash memory interface circuits
• High-density data routing applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'APWR' corresponds to the TSSOP-20 package and tape-and-reel orientation required for your assembly process. Confirm that the 3.3-V ABT logic family aligns with your system's voltage domains, as this component differs from standard LV or HC series devices. Ensure thermal management meets the specified operating temperature range during design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 3.3-V systems with high-speed requirements and strong drive needs. It serves as a suitable alternative to standard LV245 variants where higher current drive (64 mA) is necessary. Consider the TSSOP-20 footprint constraints and verify compatibility with existing PCB layouts designed for SOIC or similar narrow packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH245A series of octal bus transceivers. It is part of Texas Instruments' broader portfolio of logic ICs designed for mixed-voltage environments. The ABT technology combines advanced CMOS processes with bipolar pull-up/pull-down structures to achieve fast switching speeds and robust output drive characteristics compared to standard CMOS counterparts.
