74ALVC244PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVC244PW,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V. The device contains two independent four-bit buffers controlled by separate output enable inputs (1OE and 2OE). It utilizes Schmitt trigger action on all inputs for noise immunity. The component supports partial power-down applications via IOFF circuitry to prevent backflow current. It is housed in a TSSOP20 package (SOT360-1) with a body width of 4.4 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffered outputs with three-state capability controlled by dual enable inputs.
• Incorporates IOFF circuitry to disable outputs and prevent damaging backflow currents during partial power-down conditions.
• Features Schmitt trigger inputs to ensure tolerance against slow rise and fall times.

• Partial power-down mode operation
• Bus-oriented communications
• Clock driving

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP20 (SOT360-1) package variant. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet. Ensure design compatibility with the 1.65 V to 3.6 V supply voltage limits before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for bus systems. It is suitable for designs needing direct interface with TTL levels and overvoltage tolerant inputs up to 3.6 V. Consider the TSSOP20 package dimensions if space constraints require a thin shrink small outline form factor.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ALVC family of high-speed CMOS logic devices manufactured by Nexperia. The ALVC series is designed for low voltage applications while maintaining performance comparable to older logic families. The 74ALVC244 specifically provides buffering functionality for digital signal lines in mixed-voltage environments.
