XD74LS14 – Hex Inverter (Schmitt Trigger) – Xinluda
The Xinluda XD74LS14 is a 74LS-series hex inverter with Schmitt-trigger inputs in a DIP-14 package, providing six independent inverting gates with input hysteresis for clean, jitter-free switching of slow or noisy signals.
The Xinluda XD74LS14 is a low-power Schottky (74LS) TTL hex inverter with Schmitt-trigger inputs, supplied in a through-hole DIP-14 package. It contains six independent inverter gates, each featuring input hysteresis that increases noise immunity and converts slowly changing or noisy input signals into fast, clean, jitter-free output transitions. In Xinluda’s part-numbering scheme, the “XD” prefix designates the DIP through-hole version (the surface-mount SOP-14 equivalent carries the “XL” prefix).
As a drop-in functional equivalent of the industry-standard 74LS14 (SN74LS14 / DM74LS14), the XD74LS14 is widely used wherever a designer needs to square up an analog or slow-rise signal, debounce a switch, or build a simple relaxation oscillator using a resistor and capacitor on a single gate.
Key Features
- Six independent Schmitt-trigger inverter gates (hex inverter)
- Schmitt-trigger inputs with hysteresis for high noise immunity and clean switching from slow input ramps
- Different positive-going (VT+) and negative-going (VT-) input threshold levels
- Operates from a single 5 V TTL supply (VCC 4.75 V to 5.25 V)
- Output drive: IOL up to 8 mA, IOH up to -0.4 mA (push-pull / totem-pole output)
- 14-pin DIP through-hole package
- Operating temperature range 0 °C to 70 °C (commercial)
Applications
- Signal conditioning and waveform squaring of slow or noisy inputs
- Switch and contact debouncing circuits
- Simple RC relaxation oscillators and clock generators
- Logic-level inversion in TTL systems
- Noise filtering in industrial and instrumentation inputs
- Interface buffering between slow analog signals and digital logic
Why Source XD74LS14 from Pacific Component Xchange
The XD74LS14 is an offshore-brand logic part with limited authorized-distributor coverage in North America and Europe, which makes it a common pain point for buyers chasing line-down BOM gaps and end-of-life builds. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and logic devices. We help engineering and procurement teams secure scarce parts like the XD74LS14 with global sourcing reach, careful authenticity and counterfeit-avoidance practices, and worldwide shipping.
Because this is a Request-For-Quote (RFQ) item, pricing and lead time are confirmed per order based on quantity, date code, and packaging requirements. Submit an RFQ to Pacific Component Xchange for current availability, competitive quotes, and authenticity guarantees on the XD74LS14 and equivalent 74LS14 / SN74LS14 / DM74LS14 hex Schmitt-trigger inverters.
