74HC244PW-Q100,118

Overview

The Nexperia 74HC244PW-Q100,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device contains two independent output enable inputs (1OE and 2OE), each controlling four non-inverting outputs. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component is qualified to AEC-Q100 Grade 1 standards.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

• Octal bus interface
• Line driving applications
• Buffering applications

Procurement Notes

Verify the specific ordering code suffix matches the required package variant. Confirm that the automotive grade designation aligns with project requirements. Ensure the TSSOP20 package dimensions are compatible with the intended PCB layout. Check for any recent product change notices regarding manufacturing sites or materials.

Selection Notes

Select this component when an octal buffer with three-state capability is required for automotive environments. The wide supply voltage range allows operation across various logic levels. Input clamp diodes facilitate direct interfacing with higher voltage sources without external protection components. Verify thermal derating requirements for the specific operating temperature range.

Part Context

This part belongs to the 74HC244-Q100 family of octal buffers. It shares functional characteristics with the 74HCT244-Q100 but differs in input logic levels. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package. It is designed for high-speed signal buffering in mixed-voltage systems.
