What are the key features of CD54HCT14F?
- 6-channel Schmitt-trigger inputs with hysteresis for reliable edge detection on slow or noisy signals
- HCT logic family with TTL-compatible input thresholds enabling direct interface to 5 V TTL and CMOS systems
- Ceramic 14-pin DIP package rated for -55°C to +125°C military and industrial temperature range
What is CD54HCT14F used for?
CD54HCT14F is used in legacy industrial control boards and military electronics where slow or noisy digital signals need Schmitt-trigger conditioning before entering high-speed logic. Its HCT family compatibility allows it to bridge 5 V TTL outputs to CMOS logic with built-in hysteresis. The ceramic DIP package suits socketed prototyping and high-reliability designs requiring extended temperature operation.

Frequently Asked Questions
What supply voltage range and output drive current does CD54HCT14F support?
CD54HCT14F operates from a 2 V to 5.5 V supply and delivers up to 5.2 mA output sink current at each of its 6 inverter channels. The HCT input threshold is TTL-compatible at 1.2 V typical, making it directly interoperable with 5 V TTL sources without level-shifting circuits.
Why use a Schmitt-trigger inverter like CD54HCT14F instead of a standard buffer for signal conditioning?
Schmitt-trigger inputs provide hysteresis — typically 0.4 V on the HCT family — preventing multiple output transitions when an input signal has slow rise times or superimposed noise above 50 mV. CD54HCT14F's 6 independent channels let designers clean up 6 separate noisy or slow digital signals in a single 14-pin package.
What temperature range does CD54HCT14F cover, and which applications require that range?
CD54HCT14F is specified from -55°C to +125°C in a ceramic DIP, making it suitable for military avionics, aerospace ground support equipment, and industrial motor controllers exposed to extreme ambient temperatures. The ceramic 14-pin DIP package provides superior moisture resistance compared to plastic packages in high-humidity field environments.
How does CD54HCT14F compare to the commercial 74HCT14 for a 5 V industrial control board?
CD54HCT14F and 74HCT14 share the same 6-channel Schmitt-trigger inverter function and 5 V TTL-compatible inputs, but CD54HCT14F is qualified to -55°C to +125°C with a ceramic package while the 74HCT14 targets 0°C to +70°C in plastic. For industrial boards in -40°C environments, CD54HCT14F provides the wider 85-degree margin of safety.
