Product details
Overview
74HC365PW,112 from Nexperia is a hex non-inverting 3-state buffer/line driver in TSSOP16 package, operating from 2.0 V to 6.0 V supply, delivering 6.0 mA output drive at 4.5 V, with propagation delay as low as 9 ns (VCC = 6.0 V, CL = 50 pF), and specified for -40 °C to +125 °C industrial temperature range. It serves as a bidirectional bus interface or signal level translator in digital logic systems requiring controlled output enable.
For engineers reviewing the 74HC365PW,112 datasheet, 74HC365PW,112 pinout, 74HC365PW,112 application, or 74HC365PW,112 equivalent, this device is selected for high-noise-immunity bus buffering, CMOS-level signal conditioning, and low-power 3-state interfacing where precise timing, wide VCC tolerance, and thermal robustness are required.
Technical Context
The 74HC365PW,112 implements six independent non-inverting buffers, each with dedicated input and output pins and shared dual active-low output enable controls (OE1, OE2). Its CMOS architecture ensures rail-to-rail output swing, sub-100 μA ICC at 6.0 V (Tamb = 25 °C), and input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.
It supports mixed-voltage system interfacing through TTL-compatible input thresholds only in the 74HCT variant; the 74HC365PW uses CMOS-level inputs (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), and exhibits 40 pF power dissipation capacitance per buffer, enabling accurate dynamic power estimation using PD = CPD × VCC² × fi × N.

Key Features
| Feature | Design Value |
|---|---|

| Low static power | ICC ≤ 160 μA max at VCC = 6.0 V, Tamb = +125 °C - minimizes standby current in battery-backed or thermally constrained designs |
| Input clamp diodes | Integrated protection allows safe overvoltage input (up to VCC + 0.5 V) with external resistor limiting |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events |
Applications
| Industrial Bus Interface | Digital I/O Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT365PW,112 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and 3-state behavior | Better suited for interfacing with legacy 5 V TTL outputs without pull-ups | Select when driving from 5 V TTL sources; avoid if system uses pure CMOS signaling with VCC < 4.5 V |
| SN74LVC365APW | 3.3 V only (1.65–3.6 V), lower VCC min, higher speed (tpd = 5.2 ns @ 3.3 V), different pin mapping | Optimized for modern low-voltage FPGAs and SoCs; not drop-in compatible | Choose for new 3.3 V designs requiring faster timing and lower power; requires PCB redesign |
Compared with 74HCT365PW,112, the 74HC365PW,112 offers superior noise margin at low VCC but lacks TTL input compatibility; versus SN74LVC365APW, it supports wider voltage range and drop-in replacement in legacy 5 V/3.3 V mixed systems but trades off speed and quiescent current.

FAQ
What is the maximum output current per channel for 74HC365PW,112?
The 74HC365PW,112 delivers ±6.0 mA DC output current per channel at VCC = 4.5 V and Tamb = 25 °C, with VOL ≤ 0.26 V and VOH ≥ 3.98 V under those conditions. Absolute maximum continuous output current is ±35 mA, but sustained operation above ±6.0 mA may exceed recommended operating limits and affect timing or thermal performance.
Can 74HC365PW,112 interface safely with 5 V inputs while powered from 3.3 V?
Yes - its integrated input clamp diodes allow safe connection of inputs to voltages up to VCC + 0.5 V. When powered from 3.3 V, a 5 V input requires a series current-limiting resistor (e.g., 10 kΩ) to restrict IIK to ≤ ±20 mA, preventing damage and enabling reliable logic-level translation without external components.
How are the two output enable inputs (OE1 and OE2) functionally partitioned?
OE1 (pin 1) controls buffers 1–3 (1A→1Y, 2A→2Y, 3A→3Y), while OE2 (pin 15) controls buffers 4–6 (4A→4Y, 5A→5Y, 6A→6Y). Each group enters high-impedance state independently when its respective OE is HIGH, enabling selective bus segmentation and partial isolation in multi-drop architectures.
Is 74HC365PW,112 qualified for automotive applications?
No - the 74HC365PW,112 is specified for industrial temperature range (-40 °C to +125 °C) but is not AEC-Q100 qualified. Nexperia does not designate this part as automotive-grade; for automotive use, consult Nexperia's dedicated automotive logic portfolio or verify qualification status via their official automotive product selector tool.
