NXP Semiconductors N74F260N,602

Overview

N74F260N,602 from Philips Semiconductors is a dual 5-input NOR gate logic IC in a 14-pin plastic DIP package, delivering 3.5 ns typical propagation delay and 6 mA total supply current at 5 V. It operates across 0°C to +70°C, supports TTL-compatible input thresholds (V_IL = 0.8 V, V_IH = 2.0 V), and drives up to 20 mA low-level output current - used in high-speed combinational logic control for industrial timing sequencers and address decoding in legacy microprocessor systems.

For engineers reviewing the N74F260N,602 datasheet, N74F260N,602 pinout, N74F260N,602 application, or N74F260N,602 equivalent, key selection considerations include guaranteed fan-out (50/33 HIGH/LOW), absolute maximum ratings (V_CC = –0.5 to +7.0 V), AC performance under CL = 50 pF, and compatibility with 74F-family logic families in mixed-technology backplanes.

Technical Context

The N74F260N,602 implements two independent 5-input NOR gates using bipolar FET (Fairchild/74F) process technology, with totem-pole outputs and internal clamping diodes. Each gate exhibits identical DC electrical behavior: V_OL ≤ 0.50 V at I_OL = 20 mA, V_OH ≥ 2.7 V at I_OH = –1 mA, and input leakage ≤ 20 µA at V_IH = 2.7 V.

Its AC timing is characterized at V_CC = 5.0 V ±10%, T_amb = 0°C to +70°C, with t_PLH/t_PHL max of 6.5 ns and min of 2.0 ns under CL = 50 pF and RL = 500 Ω. The device adheres to IEC/IEEE logic symbol conventions and supports standard FAST unit loading (1.0 U.L. = 20 µA HIGH / 0.6 mA LOW).

FAQ

What is the maximum operating temperature range for the N74F260N,602?

The N74F260N,602 is rated for operation from 0°C to +70°C ambient temperature, consistent with commercial-grade specifications. Its absolute maximum storage temperature extends to –65°C to +150°C, but sustained operation outside the recommended range may degrade parametric performance or reliability. The N74F260N,602 must be derated per Philips' thermal guidelines when used near upper limits.

Does the N74F260N,602 support 3.3 V operation?

No, the N74F260N,602 is specified only for V_CC = 4.5 V to 5.5 V operation and does not guarantee functionality at 3.3 V. Its input thresholds (V_IH = 2.0 V, V_IL = 0.8 V) and output drive characteristics are optimized for 5 V TTL systems. Using the N74F260N,602 at 3.3 V risks undefined logic states and insufficient noise margins.

How many inputs does each NOR gate in the N74F260N,602 have?

Each of the two independent NOR gates in the N74F260N,602 has exactly five inputs - labeled D0a–D0e for Gate 0 and D1a–D1e for Gate 1. The function table confirms that any single high input forces the corresponding output low, and only when all five inputs are low does the output go high - confirming strict 5-input NOR behavior per gate.

Can the N74F260N,602 drive standard TTL loads directly?

Yes, the N74F260N,602 can drive standard TTL loads directly: its 20 mA low-level output current meets or exceeds the 1.6 mA sink requirement of one standard TTL input, and its fan-out rating of 50 units (HIGH) / 33 units (LOW) reflects verified compatibility. The N74F260N,602 maintains valid VOH/VOL levels across this loading range per its DC electrical characteristics table.

Is the N74F260N,602 pin-compatible with other 74F-series 14-pin DIP logic devices?

Yes, the N74F260N,602 uses the industry-standard 14-pin DIP pinout for dual-gate logic ICs: Pin 7 = GND, Pin 14 = V_CC, with inputs and outputs arranged symmetrically. This matches the physical layout of SN74F260N and other 74F dual-gate devices like 74F00 or 74F02, enabling socket reuse and board-level substitution where logic function aligns.
