SN74LVC1G14DRYR Texas Instruments Single Schmitt-Trigger Inverter 1.65-5.5V 32mA 4.6ns SON-6

SN74LVC1G14DRYR Product Overview

The SN74LVC1G14DRYR is a single Schmitt‑trigger inverter (NOT gate) from Texas Instruments, part of the 74LVC low‑voltage CMOS logic family. Housed in an ultra‑compact 6‑pin SON (DRY) package measuring just 1.45mm × 1.0mm, the SN74LVC1G14DRYR operates over a wide supply voltage range of 1.65V to 5.5V, supporting 5V VCC operation and accepting inputs up to 5.5V.

The SN74LVC1G14DRYR contains a single inverter and performs the Boolean function Y = A. Its Schmitt‑trigger input architecture provides different threshold levels for positive‑going (VT+) and negative‑going (VT–) signals, delivering hysteresis (ΔVT) that enables the device to tolerate slow or noisy input signals. With a maximum propagation delay (tpd) of just 4.6ns at 3.3V and output drive capability of ±24mA at 3.3V, the SN74LVC1G14DRYR is ideal for high‑speed signal processing. Quiescent current (ICC) is only 10µA maximum, making it extremely power‑efficient.

The SN74LVC1G14DRYR also supports Ioff partial‑power‑down mode, which disables the output when the device is powered off, preventing damaging backflow current. It operates over a temperature range of -40℃ to +125℃ and features latch‑up performance exceeding 100mA per JESD 78, Class II.

SN74LVC1G14DRYR Key Advantages

The SN74LVC1G14DRYR offers several key advantages for designers:

Schmitt‑trigger input delivers robust noise immunity: The built‑in Schmitt trigger provides different threshold levels for positive‑ and negative‑going signals, creating voltage hysteresis. This enables the SN74LVC1G14DRYR to tolerate slow‑changing or noisy input signals, making it ideal for signal shaping and noise filtering in noise‑sensitive environments such as industrial settings and long‑distance transmission lines.

Ultra‑low power with wide voltage range: Quiescent current of just 10µA combined with a 1.65V to 5.5V supply range allows the device to be used across battery‑powered low‑power devices (portable audio, wireless peripherals) and 5V systems (digital TVs, embedded PCs) – one part covers multiple voltage platforms.

High speed and high drive capability: Maximum propagation delay of only 4.6ns at 3.3V and ±24mA output drive enable direct driving of multiple loads or LEDs without additional buffer components.

Ultra‑compact package saves PCB space: The SON-6 (1.45mm × 1.0mm) package is one of the smallest logic packages available, making the SN74LVC1G14DRYR ideal for space‑constrained, high‑density PCB designs.

Ioff partial‑power‑down protection: Supports partial‑power‑down mode, automatically disabling the output when powered off to prevent backflow current damage, providing enhanced reliability for multi‑power systems.
