Product details
Overview
N74F14N,602 from Philips Semiconductors is a hex inverter Schmitt trigger IC in a 14-pin plastic DIP package, operating at 5V ±10%, with 5.0 ns typical propagation delay, 18 mA typical total supply current, and input hysteresis of 0.4–0.8 V. It transforms slow-rising/falling TTL inputs into clean, jitter-free outputs and is used in noise-prone digital interface conditioning.
For engineers reviewing the N74F14N,602 datasheet, N74F14N,602 pinout, N74F14N,602 application, or N74F14N,602 equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), Schmitt-trigger input thresholds (VT+ = 1.4–2.0 V, VT– = 0.7–1.1 V), TTL-compatible I/O loading, and DIP-14 mechanical compatibility for legacy board designs.
Technical Context
The N74F14N,602 integrates six independent Schmitt-trigger inverters, each comprising a positive-feedback input stage followed by a Darlington level shifter and TTL totem-pole output driver. Its dual-threshold behavior (VT+ and VT–) enables reliable signal cleanup of noisy or slowly transitioning waveforms.
Each inverter accepts standard TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and delivers TTL-compliant outputs (VOH ≥ 2.5 V at IOH = –1 mA, VOL ≤ 0.5 V at IOL = 20 mA), with fan-out capability of 50 high / 33 low unit loads per output.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74F14N | Same logic function, identical pinout, same DIP-14 package; TI version with marginally higher ICC (23 mA typ) | Identical use cases; validated in TI's industrial-grade qualification program | Select when sourcing from TI-authorized channels or requiring TI-specific reliability documentation |
| 74HC14N | CMOS technology: lower ICC (≈4 µA), wider VCC range (2–6 V), but slower tPLH/tPHL (≈20 ns typ) and reduced noise margin | Better for battery-powered or multi-voltage systems; unsuitable for high-speed TTL interconnect | Prefer for low-power or 3.3 V–5 V mixed-rail designs where speed <50 MHz is acceptable |

FAQ
What is the maximum operating temperature for N74F14N,602?
The N74F14N,602 is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the Philips 1990 datasheet. The device maintains full functionality-including propagation delay, threshold voltages, and output drive-across this full range without derating. N74F14N,602 is not qualified for extended commercial (0°C to +70°C) or military temperature grades.
Does N74F14N,602 support 3.3 V operation?
No, N74F14N,602 is specified only for 5 V ±10% operation (4.5 V to 5.5 V). Its internal Darlington output stage and Schmitt-trigger bias network require nominal 5 V for correct threshold behavior and output voltage levels. Applying 3.3 V may result in undefined VT+ and VT–, marginal VOH, or failure to meet AC timing specs. For 3.3 V systems, consider 74LVC14 or similar CMOS alternatives instead of N74F14N,602.
Is N74F14N,602 pin-compatible with 74LS14?
Yes, N74F14N,602 is pin-compatible with 74LS14 in the 14-pin DIP package: both share identical pin assignments for VCC (14), GND (7), and the six inverter input/output pairs (D0/Q0 through D5/Q5). However, N74F14N,602 offers faster propagation delay (5.0 ns vs. 15 ns typ) and higher output drive (20 mA vs. 8 mA), making it a performance upgrade-not just a footprint match. N74F14N,602 retains full functional equivalence in logic behavior.
What is the input hysteresis value of N74F14N,602?
The input hysteresis (∆VT) of N74F14N,602 is specified as 0.4 V minimum to 0.8 V maximum at VCC = 5.0 V, derived from VT+ (1.4–2.0 V) minus VT– (0.7–1.1 V). This hysteresis enables reliable rejection of noise spikes up to ±400 mV and eliminates metastability on slowly changing signals. The value is process- and temperature-stable due to resistor-ratio design, and is explicitly measured-not derived-in the DC Electrical Characteristics table of the Philips datasheet for N74F14N,602.
Can N74F14N,602 drive multiple TTL inputs directly?
Yes, N74F14N,602 can drive up to 50 TTL inputs in the high state and 33 in the low state, per output, based on its defined unit load (U.L.) rating. Each output delivers IOH = –1 mA and IOL = 20 mA, matching standard TTL fan-out requirements. This capability is documented in the Input and Output Loading and Fan-Out Table of the N74F14N,602 datasheet and verified under recommended operating conditions (VCC = 4.5–5.5 V, Tamb = –40°C to +85°C).
