74HCT08D,653

Overview

The Nexperia 74HCT08D,653 is a quad 2-input AND gate from the 74HCT logic family. 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-compatible input levels and includes clamp diodes on all inputs. It utilizes a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Feature Summary

• TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems
• CMOS low power dissipation characteristics combined with high noise immunity
• Input protection via integrated clamp diodes allowing current limiting resistor usage

Applications

• Digital logic circuits requiring quad 2-input AND functionality
• Systems utilizing TTL-level signal interfaces
• General-purpose digital processing applications

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm RoHS compliance status and ensure the component meets JEDEC standards relevant to the target application environment before finalizing procurement specifications.

Selection Notes

Select this component when TTL-compatible inputs are necessary alongside CMOS performance benefits. Ensure the operating voltage remains strictly between 4.5 V and 5.5 V. Verify that the thermal requirements align with the specified -40 °C to +125 °C operating range for the selected package.

Part Context

This part belongs to the 74HCT series, which bridges HC logic speed with TTL voltage compatibility. The 'D' designation indicates the SO14 surface-mount package. The ',653' suffix identifies the specific tape and reel packaging configuration provided by Nexperia.

Replacement Considerations

Compatible substitutes include other manufacturers' 74HCT08 devices in SO14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength against the original datasheet specifications.
