Diodes Incorporated 74LVC14AT14-13 Hex Inverting Schmitt Trigger

The 74LVC14AT14-13 from Diodes Incorporated is a high-performance, six-channel inverting Schmitt trigger device designed to operate from a 1.65V to 5.5V power supply, making it suitable for a wide range of applications, including those that interface with 3.3V and 5V systems. This versatility in voltage compatibility ensures that the device can be used in mixed-voltage environments, which is common in modern electronic systems.

Each inverter in the 74LVC14AT14-13 utilizes Schmitt-trigger action, which provides the gates with hysteresis, a feature that enhances noise immunity and transforms slowly changing input signals into sharply defined jitter-free output signals. This characteristic is particularly beneficial in applications where noise is present on the signal lines, or when slow-rising or falling edges are encountered.

The device is offered in a TSSOP-14 (Thin Shrink Small Outline Package) configuration, which is a space-saving package ideal for applications where board space is at a premium. The 74LVC14AT14-13 is also characterized for operation from -40°C to +125°C, ensuring reliable performance across a broad range of operating conditions, making it suitable for industrial, automotive, and consumer applications.

Key features of the 74LVC14AT14-13 include:

• High noise immunity with Schmitt-trigger action
• Wide operating voltage range (1.65V to 5.5V)
• Low power consumption
• Capability to drive up to 24mA at the output
• ESD protection exceeds JESD 22
• Latch-up performance exceeds 250mA per JESDEC Standard

The device is also fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing damaging current backflow through the device when it is powered down.

In summary, the 74LVC14AT14-13 is a robust, versatile Schmitt trigger inverter that provides reliable performance for a myriad of digital applications. Its noise immunity, wide operating voltage range, and low-power consumption make it an excellent choice for designers looking to implement a high-performance inverting Schmitt trigger in their systems.
