SN74AC16WBQARQ1

Overview

The SN74AC16-Q1 is an automotive-grade hex inverter featuring Schmitt-trigger inputs and open-drain outputs. It operates within a supply voltage range of 1.5V to 6V. The device provides continuous output drive currents up to 24mA at 5V, with short-burst capability reaching 75mA. Propagation delays are specified as low as 4.5ns at 5V with a 50pF load. Operating temperatures span from -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified for automotive applications with defined temperature grades and ESD classification levels.
• Schmitt-trigger input architecture provides hysteresis for tolerance against slow or noisy signals.
• Open-drain CMOS outputs allow wired-OR configurations and direct driving of inductive loads via clamp diodes.

Applications

• Control indicator LEDs
• Drive low-voltage relay coils
• Wired-OR logic implementations

Procurement Notes

Verify the specific package variant (PW or BQA) required for your design, as availability varies by manufacturer revision. Confirm that the selected part number suffix aligns with your tape-and-reel quantity requirements. Ensure all electrical parameters meet system thresholds before finalizing procurement orders.

Selection Notes

Select this component when open-drain functionality is necessary for wired-logic connections or inductive load driving. The wide 1.5V to 6V supply range supports various logic families. Verify that the 50pF capacitive load limit is not exceeded to maintain specified switching performance.

Part Context

This device belongs to the SN74AC16-Q1 family of automotive hex inverters. It shares the AC logic series characteristics but is distinguished by its open-drain output structure and Schmitt-trigger inputs, differentiating it from standard push-pull logic gates.

FAQ

How do unused inputs behave on this device?

Unused inputs must be terminated to either VCC or ground to prevent undefined operational states. They should not be left floating.

What is the maximum capacitive load supported?

The device can drive a load with total capacitance less than or equal to 50pF while meeting all datasheet specifications.
