Applications
The SN7414D is widely used in digital logic systems requiring signal conditioning and noise rejection, such as microcontroller input debouncing and clock signal cleanup in industrial control equipment. Its Schmitt trigger inputs make it ideal for converting slow or noisy analog-level signals into clean digital waveforms in sensor interfaces and communication circuits. The device is also commonly deployed in oscillator circuits, wave-shaping networks, and bus driver applications where TTL-level signal integrity is critical.

Frequently Asked Questions
What is the operating voltage range of the SN7414D?
The SN7414D operates on a 4.75V to 5.25V supply voltage, which is the standard TTL logic supply range. This narrow tolerance ensures proper logic threshold levels and reliable switching performance across the full temperature range.
How many inverter channels does the SN7414D provide?
The SN7414D provides 6 independent Schmitt trigger inverter channels (hence 'Hex' in the name), each with a single input. Each channel can sink up to 16mA (0.016A) output current, making it suitable for driving standard TTL and CMOS loads.
What package does the SN7414D come in?
The SN7414D is packaged in a 14-Pin SOIC (Small Outline Integrated Circuit) package, also coded as R-PDSO-G14. This surface-mount package is ideal for compact PCB designs and supports standard SMT assembly processes.
What are the typical applications for the SN7414D?
The SN7414D is commonly used in signal conditioning, noise filtering, clock signal cleanup, oscillator circuits, and input debouncing for microcontrollers. Its Schmitt trigger hysteresis makes it especially effective in industrial control systems and sensor interface circuits where noisy or slowly changing signals need to be converted to clean digital logic levels.
Is the SN7414D compatible with CMOS logic?
The SN7414D is a TTL-family device with standard TTL logic levels (VIL ≤ 0.8V, VIH ≥ 2.0V). It can interface with 5V CMOS logic directly, but may require level-shifting when used with 3.3V CMOS systems. The 16mA sink current output is sufficient to drive most TTL and standard CMOS loads.
