74HCT08D-Q100,118

Overview

The 74HCT08D-Q100,118 is a quad 2-input AND gate from the Nexperia 74HCT08-Q100 series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL input levels and CMOS low power dissipation. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• TTL input levels compatible with standard logic families
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring qualified logic gates
• Digital signal processing circuits utilizing TTL-compatible inputs
• General-purpose logic applications operating at 5 V supply

Procurement Notes

Verify the specific ordering code matches the required package variant. Confirm that the application environment adheres to the specified temperature and voltage limits. Ensure design safeguards are implemented to prevent operation beyond absolute maximum ratings. Check for any recent product change notices affecting specifications or manufacturing locations before finalizing procurement.

Selection Notes

Select this component when TTL-level compatibility is required alongside high-speed CMOS performance. The wide operating temperature range makes it suitable for harsh environments. Consider the SO14 package dimensions for PCB layout constraints. Verify that the input clamping diode capabilities align with the system's voltage interface requirements.

Part Context

This part belongs to the 74HC/HCT08-Q100 family of quad 2-input AND gates. The 'HCT' designation indicates TTL-compatible inputs, distinguishing it from the standard HC series which uses CMOS levels. The '-Q100' suffix denotes automotive qualification under AEC-Q100 standards. The 'D' suffix specifies the SO14 plastic small outline package.

Replacement Considerations

The 74HC08D-Q100,118 serves as a functional substitute if CMOS input levels are acceptable instead of TTL levels.
