Overview
The SN74AC16PWRQ1 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 (tPLZ) and 7.7ns (tPZL) at 5V with a 50pF load. It supports an operating temperature range from -40°C to +125°C and includes input/output clamp diodes for inductive load protection.
Feature Summary
- AEC-Q100 qualified for automotive applications with defined ESD classification levels.
- Schmitt-trigger inputs provide high noise immunity and tolerance for slow signal transitions.
- Open-drain CMOS outputs allow wired-OR configurations and direct driving of inductive loads via integrated clamp diodes.
Applications
- Control indicator LEDs
- Drive low-voltage relay coils
- Wired-OR logic implementations
Procurement Notes
Verify the specific ordering suffix matches the required package type, such as PW for TSSOP or BQA for WQFN. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target environment. Ensure design parameters align with the absolute maximum ratings to prevent damage during operation.
Selection Notes
Select this component when open-drain functionality is required for interfacing with different voltage domains or implementing wired-logic structures. The Schmitt-trigger inputs make it suitable for noisy environments or applications involving slow-rising signals. Verify that the load capacitance remains within recommended limits to maintain specified switching performance.
Part Context
This part belongs to the SN74AC16-Q1 family of hex inverters designed specifically for automotive electronics. It utilizes Texas Instruments' AC logic technology to deliver high-speed performance while maintaining compatibility with standard CMOS interfaces. The Q1 designation indicates compliance with automotive reliability standards.

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 function of the open-drain outputs?
Open-drain outputs can only drive the output low. In the high state, they enter a high-impedance state, allowing multiple outputs to share a common line or requiring an external pull-up resistor.
