SN74S22N

Inverter Gates Overview

The SN74S22N is a dual 4-input positive NAND gate featuring open collector outputs, belonging to the Texas Instruments 74S (Schottky) logic family. It operates within a supply voltage range of 4.75 V to 5.25 V and supports through-hole mounting in a 14-pin PDIP package. The device provides TTL-compatible inputs and includes Schmitt trigger action for noise immunity. It functions reliably across an operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Dual 4-input positive NAND gate configuration
• Open collector output structure
• Schmitt trigger input action for enhanced noise rejection
• TTL-compatible input levels

Inverter Gates Applications

• Digital logic circuit design
• Signal processing applications requiring Schmitt trigger characteristics
• General-purpose switching circuits

Inverter Gates Procurement Notes

Verify the specific manufacturer datasheet to confirm pinout compatibility and electrical specifications against current design requirements. Ensure that the open collector nature of the outputs is accounted for in the circuit design, as external pull-up resistors are typically required for proper operation. Confirm package integrity upon receipt.

Inverter Gates Selection Notes

Select this component when a dual 4-input NAND function with open collector outputs is required. The inclusion of Schmitt trigger inputs makes it suitable for noisy environments or slow-rising signal edges. Consider the 74S series speed-power trade-offs compared to other logic families like LS or HC when evaluating system performance needs.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74S (Schottky) logic family, known for high-speed operation. The SN74S22N specifically implements two independent 4-input NAND gates with open collector outputs, distinguishing it from standard push-pull output variants within the same logical category.

Inverter Gates Replacement Considerations

Cross-reference with other 74S series NAND gates such as the SN74S08 (quad 2-input) if pinout flexibility allows. Verify functional equivalence with other manufacturers' SN74S22 equivalents, ensuring matching voltage ranges and package dimensions.
