SN74AHCT1G08DCKT

Overview

The SN74AHCT1G08DCKT is a single-channel, two-input positive AND gate from the Texas Instruments SN74AHCT1G08 family. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology with TTL-compatible inputs. The device features a propagation delay of 7.9 ns at 5 V with a 50 pF load. Output drive capability is specified at 8 mA for both high and low states. It is housed in a SC-70 (SOT-553) surface-mount package with five pins and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides a single two-input positive AND logic function in a compact footprint
• Ensures compatibility with standard TTL logic levels across the full operating voltage range
• Delivers balanced output drive strength for reliable signal transmission

Applications

• Digital logic control circuits requiring simple AND operations
• Signal gating and enable functions in embedded systems
• Level shifting interfaces between TTL and CMOS components

Procurement Notes

Verify the specific suffix DCKT against the manufacturer datasheet to confirm the SC-70 package type and tape-and-reel or cut-tape handling specifications. Ensure the design accommodates the 4.5 V to 5.5 V supply requirement. Confirm that the thermal characteristics of the SC-70 package align with the system's power dissipation limits under maximum ambient temperature conditions.

Selection Notes

Select this component when a single AND gate is required with strict TTL input compatibility. The AHCT series is appropriate for designs needing robust noise immunity at 5 V operation. Consider the SC-70 package size constraints and verify that the 7.9 ns propagation delay meets the timing requirements of the target digital interface.

Part Context

This part belongs to the SN74AHCT1G08 family of single-gate logic ICs. It shares the same logical functionality as other variants but differs in packaging and handling specifications. The AHCT designation indicates advanced CMOS technology optimized for 5 V applications while maintaining compatibility with older TTL standards.

Replacement Considerations

Check for SN74AHCT1G08DRLR as a potential alternative with different packaging. Verify pinout compatibility before substitution.
