Key Features
- 6-channel Schmitt-trigger inverter with built-in hysteresis for clean switching from noisy or slow-slew input signals
- Wide supply range of 1.65 V to 5.5 V with 3-state compatible inputs enabling mixed 1.8 V to 5 V logic-level translation
- 14-pin TSSOP package with 6 mA output drive at 3.3 V and 50 pF load compatibility for high-density PCB designs
Applications
SN74LV14APWE4 is commonly used to condition slow-edge or noisy digital signals such as crystal oscillator outputs, mechanical switch inputs, and open-collector sensor lines into clean CMOS logic levels. Its Schmitt-trigger inputs prevent multiple output transitions caused by input ringing, making it essential in clock buffers, reset circuits, and level-shifting interfaces between 1.8 V and 5 V logic domains. The TSSOP package saves board space in compact consumer and industrial PCB designs.

Frequently Asked Questions
What input hysteresis does SN74LV14APWE4 provide, and how does it prevent chatter on mechanical switch inputs?
SN74LV14APWE4 features Schmitt-trigger inputs with approximately 0.9 V hysteresis at 3.3 V supply. When a mechanical switch bounces within a 0.9 V band, the output holds its logic state rather than toggling multiple times. This eliminates the need for RC debounce circuits in many keyboard and button-input designs, saving 2 passive components per input channel.
How does SN74LV14APWE4's 1.65 V to 5.5 V supply range facilitate 1.8 V to 3.3 V logic-level translation?
Powered from a 3.3 V rail, SN74LV14APWE4 accepts 1.8 V logic inputs (VIH ≥ 0.65 × VCC ≈ 2.15 V) and drives 3.3 V CMOS outputs, translating levels with propagation delay under 6 ns. This allows a 1.8 V FPGA GPIO to drive a 3.3 V peripheral without a dedicated level-shifter IC, reducing BOM by 1 part per 6 signals.
What maximum output current does SN74LV14APWE4 deliver, and how many LED indicators can it drive directly?
SN74LV14APWE4 sources up to 6 mA per output at 3.3 V supply. A standard 3 mm LED with a 330-ohm series resistor draws approximately 9 mA at 3.3 V, which exceeds the 6 mA rating per channel. For LED drive, a single output can drive one LED with a 560-ohm resistor (limiting current to 5 mA), or two outputs can be paralleled for up to 12 mA driving a brighter LED.
How does SN74LV14APWE4 compare to SN74HC14 when designing a 3.3 V crystal oscillator buffer?
SN74LV14APWE4 operates from 1.65 V to 5.5 V versus SN74HC14's 2 V to 6 V, making it the preferred choice in 3.3 V-only systems. At 3.3 V, SN74LV14APWE4 achieves propagation delay under 6 ns compared to HC14's 10 ns, resulting in sharper clock edges. Both share the same 14-pin TSSOP footprint, enabling a direct drop-in substitution without PCB changes.
