74AHCT1G00W5-7

Overview

The 74AHCT1G00W5-7 is a single 2-input positive NAND gate from the AHCT logic family, designed for operation with a power supply range of 4.5V to 5.5V. It features Schmitt trigger action at all inputs and standard totem pole output. The device provides ±8 mA output drive at 5.0V and includes ESD protection exceeding 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model standards. It operates within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Schmitt trigger input action ensures circuit tolerance for slower input rise and fall times.
• High ESD protection ratings exceed JESD 22 standards for machine, human body, and charged device models.
• Latch-up performance exceeds 100mA per JESD 78 Class II specifications.

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TVs, DVD players, DVRs, and set-top boxes
• Phones, personal navigation/GPS devices, MP3 players, cameras, and video recorders

Procurement Notes

Verify the specific package suffix 'W5' corresponds to the SOT25 footprint required for your PCB layout. Confirm that the operating voltage environment strictly remains between 4.5V and 5.5V to ensure proper logic level compatibility. Ensure unused inputs are tied to VCC or Ground as specified in recommended operating conditions to prevent undefined states.

Selection Notes

Select this component when TTL-compatible CMOS logic is required for 5V systems. The AHCT series guarantees input thresholds compatible with TTL levels while maintaining CMOS low power consumption characteristics. Verify that the SOT25 package dimensions fit within the available board space constraints compared to alternative packages like SOT353.

Part Context

This part belongs to Diodes Incorporated's 74AHCT logic family, which bridges the gap between standard CMOS and TTL logic families. The '1G' designation indicates a single-gate configuration, while '00' specifies the NAND function. The W5 suffix identifies the specific SOT25 surface-mount package variant.

Replacement Considerations

The datasheet lists the SE package (74AHCT1G00SE-7) as an alternative pin-compatible option using the SOT353 package. Cross-vendor replacements require verification of identical AHCT logic family electrical characteristics and physical footprint compatibility.

FAQ

What is the maximum propagation delay for this NAND gate?

At VCC = 5V with a 50pF load capacitance, the maximum propagation delay is 10.0 ns across the full operating temperature range of -40°C to 125°C.

How does the device handle unused inputs?

Recommended operating conditions specify that unused inputs must be held at VCC or Ground to ensure stable operation and prevent excessive current draw.
