Overview
The SN74AC16PWR is a hex inverter with 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 current of 24mA at 5V, with short burst capability up to 75mA. Maximum propagation delay is 7.7ns at 5V with a 50pF load. Operating temperature ranges from -40°C to +125°C.
Feature Summary
- Schmitt-trigger inputs provide hysteresis for noise tolerance
- Open-drain CMOS outputs allow wired-OR configurations
- Integrated clamp diodes protect against inductive loads
Applications
- Control indicator LEDs
- Drive low-voltage relay coils
- Wired-OR logic implementation
Procurement Notes
Verify the specific package marking matches the PW (TSSOP) designation. Confirm the component meets the required operating temperature range of -40°C to +125°C. Ensure the design accounts for the open-drain nature of the outputs by including appropriate pull-up resistors if high states are required.
Selection Notes
Select this component when Schmitt-trigger input noise immunity is necessary. The open-drain architecture supports driving higher voltage loads or implementing wired-logic functions. Verify that the application requires inverting logic signals and can accommodate the specific electrical characteristics of the AC series.
Part Context
This part belongs to the Texas Instruments SN74AC family of high-speed CMOS logic devices. The 'PW' suffix indicates a 14-pin Thin-Shrink Small-Outline Package (TSSOP). It is designed for general-purpose digital applications requiring robust signal integrity and flexible output driving capabilities.

FAQ
How should unused inputs be handled?
Unused inputs must be terminated to either VCC or ground to prevent undefined operational states.
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 via a pull-up resistor.
