Key Features
- Quad 2-input AND gate in 74LS family delivering TTL-compatible 5 V logic with 8 mA output sink current per gate
- 14-pin SOIC package providing 4 independent AND functions with 15 pF load capacitance for mid-speed digital logic designs
- 74LS series low-power Schottky technology balancing propagation delay and power consumption for industrial and consumer logic boards
Applications
SN74LS08DRG4 is widely used in digital logic circuits requiring AND-gate combinational logic such as address decoding, enable signal generation, and interrupt masking in microprocessor-based systems. Its 5 V TTL compatibility makes it suitable for legacy industrial controllers, embedded bus interfaces, and FPGA glue logic where discrete AND gates reduce programmable logic utilization. The quad configuration allows multiple logic functions to be realized with a single 14-pin SOIC device.

Frequently Asked Questions
How many AND gate functions does SN74LS08DRG4 provide and what is each gate's input configuration?
SN74LS08DRG4 provides 4 independent 2-input AND gates in a single 14-pin SOIC package. Each gate has 2 TTL-compatible inputs and 1 output, with an 8 mA sink current capability and 15 pF rated load capacitance, enabling direct drive of standard TTL or CMOS logic inputs at 5 V.
What output drive current does SN74LS08DRG4 support and how many standard TTL loads can it drive?
Each AND gate output of SN74LS08DRG4 sinks up to 8 mA (I_OL max), which is sufficient to drive 10 standard LS TTL inputs rated at 0.8 mA each. This fan-out of 10 makes SN74LS08DRG4 suitable for bus buffering in 5 V backplane circuits without requiring additional line drivers.
How does SN74LS08DRG4 in 74LS family compare to 74HC08 for a 3.3 V microcontroller design?
SN74LS08DRG4 operates on 5 V with TTL input thresholds, while 74HC08 supports 2 V to 6 V supply with CMOS-level inputs. For a 3.3 V MCU system, 74HC08 is preferable because its CMOS input thresholds match 3.3 V logic levels directly, whereas LS inputs require a 5 V supply and level-shifting to interface safely with 3.3 V GPIO outputs.
In which legacy industrial control retrofits is SN74LS08DRG4 a common replacement part?
SN74LS08DRG4 is a standard replacement in legacy 5 V TTL-based industrial PLCs, relay logic boards, and motor control panels originally designed with 74LS08 logic. Its 14-pin SOIC footprint is a direct substitute for ceramic DIP 74LS08 packages when upgrading boards to surface-mount assembly without redesigning the digital logic schematic.
