Overview
The SN74ACT16WBQARQ1 is an automotive-grade hex Schmitt-trigger inverter featuring open-drain outputs and TTL-compatible inputs. It operates within a supply voltage range of 4.5V to 5.5V, supporting continuous output drive currents up to 24mA at 5V with short-burst capability reaching 75mA. The device ensures fast operation with a maximum propagation delay of 7.2ns. Designed for robust signal integrity, it handles slow and noisy input signals effectively. It is housed in a WQFN-14 package (BQA) measuring 3mm by 2.5mm, suitable for surface-mount installation across an operating temperature range of -40°C to +125°C.
Feature Summary
- TTL-compatible Schmitt-trigger inputs provide high tolerance for slow and noisy input signals through defined hysteresis.
Applications
- Control indicator LEDs
- Drive low-voltage relay coils
- Wired-OR configurations using open-drain outputs
Procurement Notes
Verify the specific ordering suffix 'WBQARQ1' against the manufacturer's official documentation to confirm the exact package type, tape-and-reel quantity, and environmental compliance status. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for automotive-grade components.
Selection Notes
Select this component when designing circuits requiring logic inversion with open-drain capabilities and noise immunity. It is appropriate for applications interfacing with TTL-level signals or driving loads such as LEDs and relays where wired-logic functionality is needed. Verify that the system power supply remains strictly within the 4.5V to 5.5V range to maintain specified electrical characteristics.
Part Context
This part belongs to the SN74ACT16-Q1 family of automotive logic devices manufactured by Texas Instruments. It provides six independent inverters in a compact form factor. The product line is designed to meet automotive reliability standards while offering CMOS performance with TTL-compatible input thresholds for versatile digital logic integration.
Replacement Considerations
Consult the manufacturer's datasheet for officially confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully before substituting.
