Inverter Gates Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC package type. Confirm RoHS compliance status and lead finish details via the latest TI Package Option Addendum. Ensure the component meets the required thermal resistance specifications for the intended PCB layout.

Inverter Gates Selection Notes

Select this part when TTL-compatible inputs and standard 5V operation are required. Verify that the SOIC package dimensions fit the board space constraints. Consider unused input handling requirements as specified in the layout guidelines to prevent undefined operational states.

Inverter Gates Part Context

Part of the SN74HCT08 family of quadruple 2-input positive-AND gates. Available in various packages including SSOP, PDIP, SOP, and TSSOP. The 'D' suffix specifically denotes the Small Outline Integrated Circuit (SOIC) package variant.

Inverter Gates FAQ

What is the Boolean function performed by the SN74HCT08D?

Each gate performs the Boolean function Y = A • B in positive logic.

How should unused inputs be handled?

All unused inputs must be connected to a logic high or logic low voltage to prevent floating and undefined operational states.
