SN74ALVCH244PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH244PWRE4 is an octal buffer and line driver from the ALVCH logic family, manufactured by Texas Instruments. It features eight non-inverting inputs and outputs with three-state capability, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a propagation delay of 3.1 ns and 2.8 ns, output drive currents of -24 mA (high) and 24 mA (low), and a maximum static current of 10 uA. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the RE4 suffix to ensure correct packaging and compliance specifications. Confirm that the required voltage levels align with the 1.65 V to 3.6 V operational range. Check datasheet details for specific thermal characteristics and pinout configurations relevant to the TSSOP-20 footprint before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation combined with high-speed data buffering. The ALVCH series offers a balance of speed and power efficiency suitable for portable and battery-operated devices. Ensure input voltages do not exceed the absolute maximum ratings to prevent damage. Consider the three-state output feature for managing multiple drivers on shared bus lines effectively.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74ALVCH244 series of octal buffers and line drivers. It shares the same logical function and pinout configuration with variants such as SN74ALVCH244PWR and SN74ALVCH244PW. The primary distinction lies in the manufacturing revision and packaging specifics indicated by the suffix codes, while maintaining identical electrical performance characteristics defined by the ALVCH technology node.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes include SN74ALVCH244PWR and SN74ALVCH244PW. Verify pin compatibility and voltage ranges when considering cross-family alternatives like SN74LVCH244APWR or SN74AHC244PWR, as their electrical specifications differ significantly.
