Overview
The SN74AHCT08RGYR is a quadruple 2-input positive-AND gate from the Texas Instruments AHCT logic family, housed in a 14-pin VQFN package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to 125°C. The device features TTL-compatible inputs allowing up translation from 3.3 V to 5 V. Electrical characteristics include low-level output current of 8 mA and high-level output current of -8 mA. Propagation delay ranges from 5 ns to 9 ns depending on load capacitance.
Feature Summary
- TTL-voltage compatible inputs enable signal up translation from 3.3 V to 5 V
- Low-drive outputs with slow rise and fall times minimize signal ringing
- High ESD protection performance exceeding standard JESD ratings
Applications
- Servers
- Network switches
- PCs and notebooks
- Electronic points-of-sale
Procurement Notes
Verify the specific ordering suffix 'RGYR' corresponds to the VQFN-14 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Ensure the component meets MIL-PRF-38535 standards if required for your application, as production processing varies between commercial and military grades.
Selection Notes
Select this component when TTL-to-CMOS level translation is required at 5 V operation. The slow edge rates are suitable for bus-interface applications where output ringing must be minimized. Verify that the 8 mA drive capability meets the load requirements and that the 14-pin VQFN footprint fits the PCB layout constraints.
Part Context
This part belongs to the SNx4AHCT08 series of quadruple 2-input AND gates. The AHCT series combines CMOS technology with TTL-compatible input thresholds. The RGY suffix specifically denotes the 14-pin Very Small Quad Flat No-Lead (VQFN) package variant manufactured by Texas Instruments.

FAQ
How does the SN74AHCT08RGYR handle unused inputs?
All unused inputs must be connected to either VCC or GND to prevent undefined operational states caused by floating voltages.
What is the maximum input voltage tolerance?
Inputs are overvoltage tolerant, allowing them to accept voltages up to 5.5 V even when the supply voltage (VCC) is lower.
