Overview
The SN74AHCT1G08DRLRG4 is a single 2-input AND gate from Texas Instruments' AHCT logic family, housed in an SOT-553 package. It operates on a 4.5 V to 5.5 V supply and provides 8 mA output drive capability. The device features a propagation delay of 7.9 ns at 5 V with 50 pF load and functions within a -40°C to +125°C temperature range.
Feature Summary
- Provides CMOS-compatible input levels while accepting standard TTL-driven inputs for direct interface compatibility.
- Delivers high-speed switching performance suitable for timing-critical digital signal processing applications.
- Offers robust output drive strength to maintain signal integrity across connected loads.
Applications
- Digital logic circuit implementation
- Signal gating and masking operations
- Data path control logic
Procurement Notes
Verify the complete part number including the RG4 suffix to ensure compliance with specific environmental standards. Confirm the SOT-553 package availability matches your PCB footprint requirements. Cross-reference the datasheet revision to validate electrical characteristics against your design specifications before finalizing procurement.
Selection Notes
Select this component when TTL-level input compatibility is required alongside CMOS noise immunity. The AHCT series bridges the voltage threshold gap between older TTL systems and modern CMOS logic. Ensure the operating voltage remains strictly within the 4.5 V to 5.5 V range to guarantee correct logical thresholds and performance metrics.
Part Context
This part belongs to the SN74AHCT1G08 family of single-function gates. It serves as a compact solution for basic Boolean logic operations in space-constrained designs. The AHCT designation indicates specific input threshold characteristics tailored for mixed-voltage system integration.
Replacement Considerations
SN74AHCT1G08DRLR is the primary equivalent without the environmental suffix. SN74AHC1G08DRLR offers similar functionality but requires CMOS-level input signals rather than TTL-compatible levels.
