Product details
Overview
74HC365N,652 from NXP Semiconductors is a hex non-inverting buffer/line driver with 3-state outputs, controlled by two active-low output enable inputs (OE1, OE2). It operates from 2.0 V to 6.0 V, delivers ±7.8 mA output drive at 6.0 V, and supports industrial temperature range (−40 °C to +125 °C) in a 16-pin DIP package. It is used for bus interfacing, data routing, and level translation in digital logic systems.
For engineers reviewing the 74HC365N,652 datasheet, 74HC365N,652 pinout, 74HC365N,652 application, or 74HC365N,652 equivalent, key selection criteria include 3-state control timing (enable/disable times ≤38 ns at 4.5 V), CMOS-level input compatibility, low static current (≤160 µA at 125 °C), and DIP16 through-hole mounting for prototyping and legacy board designs.
Technical Context
The 74HC365N,652 implements six independent non-inverting buffer channels, each with dedicated input (nA) and output (nY), grouped under two shared 3-state controls (OE1 for channels 1–3, OE2 for channels 4–6). Its CMOS input structure includes clamp diodes enabling safe interface to voltages exceeding VCC when current-limiting resistors are used.
It complies with JEDEC standard no. 7A and features ESD protection exceeding 2000 V (HBM) and 200 V (MM). Static and dynamic performance is specified across −40 °C to +125 °C, with propagation delay ≤25 ns (typical) and transition time ≤15 ns (typical) at VCC = 4.5 V and CL = 50 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V. |
| Output drive | ±7.8 mA at VCC = 6.0 V - sufficient to drive 50-pF loads and standard TTL/CMOS inputs without external buffering. |
| Propagation delay | ≤25 ns max at VCC = 4.5 V - ensures timing integrity in high-speed digital buses up to ~20 MHz. |
| 3-state enable/disable time | ≤38 ns max at VCC = 4.5 V - enables fast bus arbitration and multiplexed data sharing between multiple drivers. |
| Input clamp diodes | Integrated - allows safe connection of inputs to voltages > VCC using series current-limiting resistors. |
| Operating temperature | −40 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-temperature embedded applications. |
| Static supply current | ≤160 µA at +125 °C - minimizes quiescent power in always-on subsystems. |
Pinout & Package
DIP16 plastic dual in-line package (SOT38-1), 16 leads, 300-mil width, long-body through-hole format suitable for breadboarding, socketing, and legacy PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Output enable 1 (active LOW) | Controls 3-state output for channels 1–3; LOW enables outputs, HIGH places them in high-impedance OFF-state. |
| 2 (1A) | Data input 1 | CMOS-level input for first buffer channel; accepts 0–VCC logic levels with clamp diode protection. |
| 3 (1Y) | Data output 1 | Non-inverting buffered output for channel 1; drives loads up to ±7.8 mA at 6.0 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC365D,118 | SO16 surface-mount package (SOT109-1); same electrical specs and pinout mapping but different thermal profile (Ptot = 500 mW vs. 750 mW for DIP16). | Suitable for space-constrained PCBs; requires reflow soldering and lacks through-hole mechanical retention. | Select when board area is limited and automated assembly is available; verify thermal margin under full-load conditions. |
| SN74HC365N | Identical function and DIP16 package; manufactured by Texas Instruments; VIH/VIL thresholds match NXP spec (e.g., VIH ≥3.15 V at 4.5 V), but HBM ESD rating is 2000 V (same) and MM rating is 200 V (same). | Drop-in replacement in TI-design ecosystems; validated in TI reference designs for industrial IO modules. | Choose for supply chain diversification or TI-centric BOMs; no layout or firmware changes required. |
Compared with 74HC365D,118 and SN74HC365N, the 74HC365N,652 offers superior thermal dissipation (750 mW) for high-duty-cycle bus driving and native NXP qualification for extended temperature operation - making it preferred for ruggedized, through-hole prototyping and legacy system repair.

FAQ
What is the maximum supply voltage rating for the 74HC365N,652?
The 74HC365N,652 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V may cause increased leakage or accelerated aging; sustained use at 7.0 V is not advised. The 74HC365N,652 is rated for continuous operation at 6.0 V across its full temperature range (−40 °C to +125 °C).
Does the 74HC365N,652 support TTL-level inputs?
No - the 74HC365N,652 is a CMOS device with CMOS-level input thresholds (VIH ≥3.15 V at VCC = 4.5 V), not TTL-compatible. For TTL input compatibility, use the pin-compatible 74HCT365N variant instead. The 74HC365N,652 requires input high signals ≥70% of VCC to guarantee recognition; direct connection to standard TTL outputs (2.4 V VOH) may fail at VCC ≥4.5 V.
How are the output enable pins OE1 and OE2 configured on the 74HC365N,652?
OE1 (pin 1) controls outputs 1Y–3Y (channels 1–3), and OE2 (pin 15) controls outputs 4Y–6Y (channels 4–6). Both are active-LOW: a logic LOW enables the associated outputs, while a HIGH forces them into high-impedance OFF-state. This allows independent gating of two logical bus segments - for example, isolating memory and peripheral address lines simultaneously.
Can the 74HC365N,652 be used with supply voltages below 2.0 V?
No - the 74HC365N,652 is not characterized or guaranteed for operation below 2.0 V. At VCC < 2.0 V, parameters such as propagation delay, output drive, and noise margins degrade unpredictably. The datasheet specifies minimum VCC = 2.0 V for full functionality; for sub-2 V logic, consider specialized ultra-low-voltage families like NXP's 74LVC series.
What is the purpose of the input clamp diodes in the 74HC365N,652?
The integrated input clamp diodes in the 74HC365N,652 protect against overvoltage by shunting currents to VCC or GND when input voltage exceeds those rails by >0.5 V. When used with external current-limiting resistors, they enable safe interfacing to signals up to 12 V - for example, connecting industrial 5 V or 12 V sensors directly to the 74HC365N,652 inputs without external protection circuitry.
