74AC20MTC

Overview

The onsemi 74AC20MTC is a dual 4-input NAND gate manufactured using AC CMOS technology. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature range from -40°C to +85°C. The device features outputs capable of sourcing and sinking 24mA. Propagation delays are specified at 10ns maximum for high-to-low transitions and 9ns maximum for low-to-high transitions at 5.0V. Input leakage current is limited to ±1µA, with quiescent supply current capped at 20µA.

Feature Summary

• Dual 4-input NAND logic function
• High output drive capability of 24mA
• Reduced power consumption compared to previous generations

Applications

• General-purpose digital logic circuits
• Memory interface control
• Microprocessor system support

Procurement Notes

Verify the specific package variant against the datasheet ordering information. Confirm that the MTC suffix corresponds to the 14-lead Thin Shrink Small Outline Package (TSSOP). Ensure compatibility with JEDEC MO-153 standards for footprint design. Check for RoHS compliance documentation if required by assembly specifications.

Selection Notes

Select this component when a dual 4-input NAND configuration is required in a compact surface-mount package. The AC series offers faster switching speeds than standard 74LS equivalents while maintaining lower power dissipation. Verify input voltage thresholds align with the driving logic family at the intended operating supply voltage.

Part Context

This part belongs to the 74AC logic family, characterized by high-speed operation and reduced power consumption relative to older technologies. The 74AC20 specifically provides two independent 4-input NAND gates. The MTC designation identifies the physical TSSOP housing, distinguishing it from SOIC or DIP variants within the same logical product line.

Replacement Considerations

Cross-reference with other manufacturers' 74AC20 equivalents such as those from NXP or Texas Instruments. Ensure pinout compatibility and verify that electrical characteristics like propagation delay and output current meet the original design requirements.
