74AHCT244PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT244PW,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device provides balanced propagation delays and high noise immunity. It includes Schmitt-trigger action on all inputs and overvoltage tolerant inputs up to 5.5 V. The component is housed in a TSSOP20 package (SOT360-1) and is specified for ambient temperatures ranging from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two independent output enable controls, each managing four three-state outputs.
• Includes Schmitt-trigger action at all inputs to tolerate slower rise and fall times.
• Inputs are overvoltage tolerant, enabling use as translators in mixed voltage environments.

Buffers, Drivers, Receivers, Transceivers Applications

• Octal bus interface applications
• Mixed voltage translation between different logic families
• Line driving for signal integrity improvement

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the TSSOP20 package variant aligns with PCB footprint requirements. Ensure the TTL input threshold specification meets system logic level compatibility. Check for any recent product change notices regarding marking or assembly updates.
