Overview
The SN74AHC1G08QDCKRQ1 is a single 2-input AND gate from the Texas Instruments SN74AHC1GxxQ1 automotive qualified series. It operates within a supply voltage range of 2 V to 5.5 V and features low dynamic power consumption. The device provides an output current capability of 8 mA at both high and low logic states. Propagation delay is specified at 7 ns. It is housed in a SC-70-5 package and supports operation across an extended temperature range from -40°C to +125°C, meeting AEC-Q100 standards for automotive applications.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Wide operating supply voltage range supporting 2 V to 5.5 V systems
- Low static and dynamic power consumption suitable for battery-powered designs
- High noise immunity characteristics inherent to advanced CMOS technology
Applications
- Automotive electronic control units requiring robust logic gating
- Infotainment system signal processing and data routing
- Body electronics and sensor interface circuits
- Charging station logic control and management
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and automotive grade specification. Confirm that the SC-70-5 footprint matches the design layout. Check datasheet revisions for any pinout or electrical parameter updates. Ensure compatibility with the target supply voltage and temperature requirements before finalizing procurement.
Selection Notes
Select this component when automotive reliability and wide voltage operation are required. Compare propagation delay and output drive strength against other logic families if speed or load driving is critical. Consider the SC-70-5 package size constraints relative to available board space. Verify thermal performance under maximum load conditions within the specified temperature range.
Part Context
This device belongs to the SN74AHC1GxxQ1 family of single-function gates designed for automotive environments. It shares architectural similarities with commercial AHC logic but includes enhanced testing and qualification processes. The family offers various logic functions such as AND, OR, and NOT gates in compact packages, providing designers with flexible building blocks for complex digital circuits.
Replacement Considerations
SN74AHC1G08DCKRQ1: Commercial grade equivalent without automotive qualification. SN74AHC1G08DCKR: Non-automotive version with identical electrical specifications. SN74AHCT1G08DCKRQ1: TTL-compatible input thresholds instead of CMOS levels.
