NXP Semiconductors N74F07D,602

Overview

N74F07D,602 from Nexperia is a hex inverter/buffer driver with open-collector outputs, designed for level-shifting and wired-OR logic interfacing in 5V TTL systems. It features 4.5 ns typical propagation delay, 64 mA sink current per output, 12 V maximum output termination voltage, and operates across 0 °C to +70 °C ambient temperature.

For engineers reviewing the N74F07D,602 datasheet, N74F07D,602 pinout, N74F07D,602 application, or N74F07D,602 equivalent, key selection considerations include open-collector drive capability, fan-out compatibility with 74F/74LS families, pull-up resistor dependency for tPLH, IOL derating at elevated temperature, and SOT108–1 SO14 package constraints.

Technical Context

The N74F07D,602 implements six independent inverting buffer stages, each with an open-collector output stage capable of sinking up to 64 mA at VCC = 5.0 V and Tamb = 25 °C. Its logic function is strictly inverting (A → Y = NOT A), with no internal pull-up or active-high output capability.

It requires external pull-up resistors on all outputs to establish HIGH-level voltage - typically to 5 V or up to 12 V - and exhibits load-dependent propagation delays: tPLH improves significantly with lower pull-up resistance (e.g., 100 Ω vs. 500 Ω), while tPHL remains relatively stable. Input thresholds are VIH ≥ 2.0 V and VIL ≤ 0.8 V under recommended operating conditions.

FAQ

What is the maximum output voltage the N74F07D,602 can safely switch?

The N74F07D,602 open-collector outputs support up to 12 V when pulled up externally, as specified in the Absolute Maximum Ratings table (VOUT ≤ 12 V). This allows direct interface to 12 V logic rails or relay coils without level-shifting components. Exceeding 12 V risks permanent damage to the output transistor. The N74F07D,602 must never be used with pull-ups above 12 V, even briefly.

Can the N74F07D,602 operate from a 3.3 V supply?

No, the N74F07D,602 is not rated for 3.3 V operation. Its Recommended Operating Conditions specify VCC = 4.5 V to 5.5 V only. At 3.3 V, input thresholds (VIH ≥ 2.0 V) become marginal, propagation delay increases unpredictably, and output drive collapses - potentially causing logic failures. Use 74LVC07 or similar for 3.3 V systems instead of the N74F07D,602.

How does pull-up resistor value affect timing in the N74F07D,602?

For the N74F07D,602, tPLH (low-to-high output transition) is highly dependent on pull-up resistance: reducing RL from 500 Ω to 100 Ω improves tPLH by up to 50%, while tPHL changes minimally. However, lower RL increases steady-state power and must respect the 64 mA IOL limit - e.g., 100 Ω at 5 V draws 50 mA, staying within spec. The N74F07D,602 datasheet provides delay vs. RL curves to guide selection.

Is the N74F07D,602 pin-compatible with the SN74F07N?

Yes, the N74F07D,602 and SN74F07N share identical pinout, logic function, and electrical specifications - differing only in package: SO14 (SOT108–1) vs. DIP14 (SOT27–1). Both use the same 14-pin arrangement with GND at pin 7 and VCC at pin 14. No PCB redesign is needed when substituting N74F07D,602 for SN74F07N in reflow-assembled designs, provided footprint matches SOT108–1.

Does the N74F07D,602 include internal pull-up resistors?

No, the N74F07D,602 has no internal pull-up resistors. All six outputs are strictly open-collector and require external pull-up resistors to define the HIGH output voltage level. Without external pull-ups, outputs remain floating in the HIGH state and cannot drive logic HIGH. This design enables flexible voltage translation - e.g., pulling up to 5 V, 12 V, or other rail - which is a core feature of the N74F07D,602.
