SN74LVTH245ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH245ANSR is an octal bus transceiver from the Texas Instruments LVTH series, designed for bidirectional data communication on multipoint buses. It operates with a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device utilizes LVTTL input levels and provides high drive capability with low output currents of -32 mA (high) and 64 mA (low). It exhibits a propagation delay of 2.3 ns at 3.3 V and functions within a temperature range of -40°C to +85°C in a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data transfer across eight channels for efficient bus architecture implementation
• Features three-state outputs to facilitate direct connection to bus lines without additional buffering
• Accepts LVTTL input signals while driving compatible loads within the specified voltage range

Buffers, Drivers, Receivers, Transceivers Applications

• Multipoint bus transmission systems requiring reliable bidirectional data flow
• Memory interface circuits connecting microprocessors to storage devices
• Control signal routing in embedded systems utilizing LVTTL logic standards

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the SOIC-20 surface-mount package and tape-and-reel orientation. Confirm that the operating environment remains within the -40°C to +85°C industrial temperature rating. Ensure power supply stability between 2.7 V and 3.6 V to maintain signal integrity and prevent excessive current draw during switching transitions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring LVTTL compatibility with moderate speed requirements around 2.3 ns delay. It is suitable for applications needing higher drive strength than standard CMOS but lower power consumption than ABT families. Consider the 20-SOIC footprint for PCB layout constraints and verify thermal dissipation capabilities under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH245A family of octal bus transceivers. It shares functional similarities with the SN74ALS245ANSR but operates at lower voltages and different logic levels. Unlike the SN74HC245ANSR, it supports LVTTL inputs and offers improved drive characteristics for 3.3 V systems. The SN74LVCC3245ANSR serves as a level-shifting alternative for mixed-voltage interfaces.
