What is SN74ALS08DRE4 used for?
The SN74ALS08DRE4 is used in digital control logic, address decoding circuits, and enable/disable gating networks in industrial PLCs, embedded computing boards, and test equipment where TTL-compatible 5 V logic is required. It also serves as a signal-enable gate in memory bus arbitration, interrupt masking, and power sequencing circuits where combining two control signals into a single enable output is needed. The SOIC-14 format makes it straightforward to populate on standard SMT production lines alongside other 14-pin logic ICs.

Frequently Asked Questions
What output drive current does SN74ALS08DRE4 provide for TTL bus loads in industrial control circuits?
Each output can sink up to 8 mA (IOL) in the low state, which is sufficient to directly drive standard TTL inputs with a fan-out of 8 or resistive loads down to approximately 625 Ω on a 5 V supply rail without level-shifting.
How does SN74ALS08DRE4 compare to standard 74LS08 in terms of power and switching performance?
The ALS family offers roughly 50% lower power consumption than the LS family while maintaining comparable propagation delay of 4–7 ns, making SN74ALS08DRE4 a better choice for high-gate-count 5 V TTL designs where reducing standby current is important.
For a memory address decoder with 50 pF trace capacitance, is SN74ALS08DRE4 timing compatible?
Yes. The device is characterized at a 50 pF load capacitance, and with a typical propagation delay of 5 ns per gate, it fits easily within the address setup time budgets of standard SRAM and Flash memories operating at 5 V with 50–100 ns access times.
What YTEOL status and lifecycle risk should procurement teams consider for SN74ALS08DRE4 long-term supply?
The YTEOL value is 0, indicating the part is approaching end-of-life horizon. Design teams planning 5- to 10-year production runs should evaluate migration to the equivalent 74AHCT08 or 74HC08 logic gate family, which carries active lifecycle status and a broader distributor base for long-term availability.
