Overview
The SN74ACT14DBR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It features TTL-compatible inputs designed to handle slow and noisy signals. The device operates within a supply voltage range of 4.5V to 5.5V. It provides continuous output drive currents of ±24mA at 5V, with short-term capabilities up to ±75mA. The component supports propagation delays as low as 9.5ns and can drive 50Ω transmission lines. It is housed in a 14-SOIC package and functions across an operating temperature range of -40°C to 85°C.
Feature Summary
- TTL-compatible Schmitt trigger inputs for noise immunity
- High current output drive capability
- Capable of driving 50Ω transmission lines
Applications
- Digital signal inversion
- Switch debouncing
- Synchronous clock input inversion
Procurement Notes
Verify the specific suffix 'DBR' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and pin-out compatibility. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor components.
Selection Notes
Select this component when interfacing noisy digital signals requiring hysteresis for clean switching. It is suitable for applications needing high fan-out and fast propagation speeds within standard 5V logic systems. Consider thermal management requirements if operating near the upper temperature limits.
Part Context
This part belongs to the SN74ACT series of advanced CMOS logic devices. It serves as a functional equivalent to older 74LS14 designs but offers significantly faster switching speeds and lower power consumption. The ACT series is widely used in general-purpose digital logic applications requiring reliable signal conditioning.
Replacement Considerations
Compatible substitutes include SN74ACT14DR and SN74ACT14DRE4. Verify that replacement parts maintain the same SOIC-14 package dimensions and electrical characteristics to ensure direct board-level interchangeability without redesign.
