Inverter Gates datasheet and documents for SN74S38DR
Inverter Gates Overview
The SN74S38DR is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments in the SN74S logic series. It features open-collector outputs and is housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial temperature range from 0°C to +70°C.
Inverter Gates Feature Summary
- Contains four independent 2-input NAND buffer gates
- Features open-collector outputs requiring external pull-up resistors
- Compatible with standard TTL input levels
Inverter Gates Applications
- Digital buffering for TTL logic circuits
- Interface driving for high-voltage or current loads via open-collector configuration
- General-purpose logic inversion and signal conditioning
Inverter Gates Procurement Notes
Verify the specific suffix 'DR' confirms the SOIC-14 surface-mount package and tape-and-reel shipping format. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Ensure the operating environment remains within the specified 0°C to +70°C temperature range for reliable performance.
Inverter Gates Selection Notes
Select this component when four independent NAND buffers with open-collector outputs are required in a compact surface-mount package. It is suitable for applications needing TTL compatibility and the ability to interface with different voltage domains through external pull-up networks, provided the load does not exceed the output specifications.
Inverter Gates Part Context
This part belongs to the SN74S (Schottky) logic family, known for faster switching speeds compared to standard LS logic. The SN74S38 specifically provides buffered NAND functionality with open-collector outputs, distinguishing it from standard push-pull output variants like the SN74LS00.
Inverter Gates Replacement Considerations
Direct pin-compatible substitutes include the SN74S38D and SN74S38N. Verify that alternative packages maintain the same electrical characteristics and thermal performance requirements.
