SN74LVCH244APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH244APWT is an octal buffer and line driver from Texas Instruments, belonging to the LVCH logic family. It features eight non-inverting channels with three-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. The device utilizes TSSOP-20 surface-mount packaging. Key electrical characteristics include output drive capabilities of ±24 mA at both high and low states, with a maximum static current of 10 µA. Propagation delay is specified at 3.1 ns and 2.8 ns under standard conditions. It supports mixed-mode signal operations, allowing 5 V tolerant inputs while operating on lower voltage supplies.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWT' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with mixed-voltage compatibility. The LVCH series offers lower power consumption compared to older LVC families while maintaining similar performance. Consider the TSSOP-20 package constraints regarding board space and thermal dissipation. Verify that the 5 V input tolerance meets the source signal requirements without additional level shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74LVCH244 family of octal buffers and line drivers manufactured by Texas Instruments. The LVCH series is engineered for low voltage applications, typically ranging from 1.65 V to 3.6 V. These devices are widely used in portable and battery-operated equipment due to their energy efficiency. The family shares common architectural features but varies in packaging and suffix designations for specific handling requirements.
