Overview
The SN74AHCT08DGVR is a quadruple 2-input positive-AND gate from the SNx4AHCT08 family, manufactured by Texas Instruments. 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 a high-level output current of -8 mA and a low-level output current of 8 mA. Propagation delay (tPLH/tPHL) ranges from 1 ns to 8 ns at VCC = 5 V with a 15 pF load. The component is housed in a TVSOP-14 package.
Feature Summary
- TTL-voltage compatible inputs enable direct interfacing with 3.3 V logic sources while translating signals up to 5 V operation levels.
- Low-drive CMOS architecture provides slow rise and fall times on outputs to minimize signal ringing, overshoot, and undershoot.
- Robust latch-up performance exceeds 250 mA per JESD 17 standards, ensuring reliability under transient conditions.
Applications
- Servers
- Network switches
- PCs and notebooks
- Electronic points-of-sale
Procurement Notes
Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-14 package and Large Tape & Reel carrier configuration. Confirm that the active production status aligns with long-term supply requirements. Ensure design compatibility with the specified 4.5 V to 5.5 V supply voltage range and industrial temperature limits before finalizing procurement.
Selection Notes
Select this component when TTL input compatibility is required for 5 V systems interfacing with 3.3 V sources. The low-drive characteristic makes it suitable for bus-interface applications where minimizing output ringing is critical. Verify that the 8 mA drive strength meets the load requirements of the destination circuitry.
Part Context
This part belongs to the SNx4AHCT08 series of quadruple 2-input positive-AND gates. It utilizes CMOS technology with balanced output drive capabilities. The device performs Boolean AND functions in positive logic and is designed for general-purpose digital logic applications requiring reliable switching performance across industrial temperature ranges.

FAQ
How does the device 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 VCC is at its minimum rating.
