• Data acquisition and control circuits requiring reliable AND gate functionality
• Industrial and automotive applications operating across wide temperature ranges

Procurement Notes

Verify the specific package suffix 'R2G' corresponds to the TSSOP-14 form factor when sourcing. Confirm RoHS compliance status for the specific lot, as manufacturing processes may evolve. Ensure unused inputs are tied to appropriate logic levels during implementation to prevent floating states. Check for any recent Product Change Notices (PCN) regarding pinout or electrical parameter updates before finalizing designs.

Selection Notes

Select this component when a quad 2-input AND function is required in space-constrained surface-mount designs. The TSSOP-14 package offers a compact footprint suitable for dense PCB layouts. Consider the 2.0 V to 6.0 V operating range for compatibility with various system voltages. Evaluate the propagation delay specifications against system timing requirements at the intended supply voltage.

Part Context

This device belongs to the 74HC series of high-speed CMOS logic integrated circuits. It shares identical pinouts with the legacy LS08 device, facilitating direct replacement in existing designs. The 74HC family is characterized by wide voltage operation and compatibility with standard CMOS outputs. This specific part number represents the tape-and-reel version of the TSSOP-14 packaged variant.

Replacement Considerations

The datasheet does not list specific substitute part numbers. Designers should verify pinout compatibility with other 74HC08 variants from different manufacturers. Electrical parameters such as propagation delay and output drive strength must be compared to ensure functional equivalence in the target application.
