Product details
Overview
74HCT365PW,118 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs and CMOS outputs, operating from 4.5 V to 5.5 V supply, delivering ±6 mA output drive at VCC = 4.5 V, and supporting industrial temperature range (−40 °C to +125 °C) in TSSOP16 package - used for bus interface isolation and signal level translation in digital control systems.
For engineers reviewing the 74HCT365PW,118 datasheet, 74HCT365PW,118 pinout, 74HCT365PW,118 application, or 74HCT365PW,118 equivalent, this device is selected for bidirectional bus buffering where TTL-level input compatibility, low static current (<160 μA), fast enable/disable timing (≤53 ns disable time at 125 °C), and high-impedance output control are required.
Technical Context
The 74HCT365PW,118 implements six independent non-inverting buffers, each with dedicated active-low 3-state output enable (OE1, OE2 controlling groups of three outputs). Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure direct interfacing with legacy 5 V logic families without level shifters.
Each output supports rail-to-rail CMOS swing (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±6 mA, VCC = 4.5 V, −40 °C to +125 °C) and exhibits low dynamic power dissipation via 40 pF CPD per buffer, enabling efficient operation in high-density digital I/O expansion applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage systems |
| Input Logic Type | TTL-level - accepts 0.8 V max LOW and 2.0 V min HIGH, eliminating need for external level translation |
| Output Drive | ±6.0 mA at VCC = 4.5 V - sufficient to drive 50 pF loads with <38 ns propagation delay across full temperature range |
| 3-State Enable Timing | Enable time ≤53 ns, disable time ≤53 ns (VCC = 4.5 V, −40 °C to +125 °C) - enables precise bus arbitration in real-time control |
| Static Current | ≤160 μA at VCC = 5.5 V, −40 °C to +125 °C - supports low-power standby modes in battery-backed systems |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| ESD Rating | HBM >2000 V, CDM >1000 V - robust against handling and board-level electrostatic discharge events |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, body width 4.4 mm, lead pitch 0.65 mm, exposed pad not present - optimized for high-density PCB layouts with thermal performance derating of 8.5 mW/K above 91 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable 1 | Controls 1Y, 2Y, 3Y - asserts high-impedance state when HIGH; synchronizes group 1 buffer shutdown |
| 2 (1A) | Data input 1 | Non-inverting input for buffer channel 1 - directly connects to upstream logic or microcontroller GPIO |
| 3 (1Y) | Data output 1 | Buffered non-inverting output - drives downstream load or shared bus segment with 3-state control |
| 4 (2A) | Data input 2 | Non-inverting input for buffer channel 2 - independent of other channels for parallel data routing |
| 5 (2Y) | Data output 2 | Buffered non-inverting output - electrically isolated from 1Y but shares OE1 control |
| 6 (3A) | Data input 3 | Non-inverting input for buffer channel 3 - completes first OE1-controlled group (1Y–3Y) |
| 8 (GND) | Ground reference | Primary 0 V return path - must be low-inductance connection to minimize switching noise coupling |
| 9 (4Y) | Data output 4 | Non-inverting output controlled by OE2 - forms first output of second 3-state group (4Y–6Y) |
| 10 (4A) | Data input 4 | Non-inverting input for buffer channel 4 - starts OE2-controlled group, enabling dual-bus partitioning |
| 11 (5Y) | Data output 5 | Non-inverting output controlled by OE2 - allows independent enable/disable of two 3-channel banks |
| 12 (5A) | Data input 5 | Non-inverting input for buffer channel 5 - completes second OE2-controlled input set |
| 13 (6Y) | Data output 6 | Non-inverting output controlled by OE2 - final output of second bank, supporting full hex buffering |
| 14 (6A) | Data input 6 | Non-inverting input for buffer channel 6 - matches 5A/4A to form symmetrical dual-group structure |
| 15 (OE2) | Active-low output enable 2 | Controls 4Y, 5Y, 6Y - enables independent bus arbitration between two logical data paths |
| 16 (VCC) | Positive supply | 4.5–5.5 V power rail - requires local 100 nF ceramic decoupling adjacent to pin 16 |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates external level shifters when interfacing with 74LS or microcontroller 5 V outputs |
| Dual independent 3-state control | OE1 controls outputs 1Y–3Y; OE2 controls 4Y–6Y - enables simultaneous or staggered bus release for multi-master arbitration |
| Rail-to-rail CMOS outputs | VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±6 mA, −40 °C to +125 °C - ensures noise margin >0.7 V in 5 V systems |
| Low dynamic power | CPD = 40 pF per buffer - limits switching power to <1.8 mW per channel at 1 MHz, 5 V (PD = CPD × VCC² × fi) |
| High ESD robustness | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 system requirements without additional protection circuitry |

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 |
|---|---|---|---|
| 74HCT365D,653 | SO16 package (SOT109-1), wider body (3.9 mm), higher thermal resistance (12.4 mW/K derating above 110 °C) | Better suited for through-hole prototyping or legacy SOIC footprints; lower pin density than TSSOP | Select when board space permits larger footprint or reflow compatibility with existing SO16 tooling is required |
| SN74HCT365PWR | Texas Instruments part in 16-pin TSSOP; identical electrical specs but different ESD ratings (HBM >4000 V) and tighter VOH/VOL min/max bounds | Higher ESD margin useful in unshielded handheld medical devices; tighter DC specs ease worst-case timing closure | Choose when design requires extended HBM robustness or TI's long-term supply assurance for industrial programs |
Compared with 74HCT365D,653, the 74HCT365PW,118 offers 25 % smaller PCB area and improved thermal derating for high-temperature surface-mount assemblies; versus SN74HCT365PWR, it provides equivalent functionality at lower cost but with slightly relaxed output voltage margins under heavy load.

FAQ
What is the maximum clock frequency supported by the 74HCT365PW,118?
The 74HCT365PW,118 is not a clocked device - it is a combinational buffer with propagation delay (tpd) of ≤38 ns at VCC = 4.5 V and −40 °C to +125 °C. Its usable data rate depends on system timing margins, but it reliably handles asynchronous signals up to ~10 MHz in typical 50 pF load configurations.
Can OE1 and OE2 be tied together for unified 3-state control?
Yes - OE1 and OE2 may be connected to a single control line to enable/disable all six outputs simultaneously. This configuration reduces GPIO usage and simplifies firmware control, though it forfeits independent bank gating capability required for advanced bus arbitration schemes.
Does the 74HCT365PW,118 require external pull-up or pull-down resistors on inputs?
No - inputs have built-in clamp diodes and defined TTL thresholds; no external biasing is needed. However, floating inputs must be avoided: unused inputs should be tied to VCC or GND to prevent increased ICC and potential oscillation due to noise coupling.
Is the 74HCT365PW,118 qualified for automotive applications?
The 74HCT365PW,118 is specified for −40 °C to +125 °C and meets AEC-Q100 stress test requirements for logic devices; however, Nexperia does not issue formal automotive qualification documentation for this specific variant. For ASIL-compliant designs, consult Nexperia's automotive-grade equivalents such as the 74HCT365BQ,115 in QFN16.
