Product details
Overview
74HC365PW,118 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 ±35 mA output drive per channel with propagation delay as low as 9 ns at VCC = 6.0 V and CL = 50 pF, used for bus interface isolation and signal fan-out in industrial control backplanes.
For engineers reviewing the 74HC365PW,118 datasheet, 74HC365PW,118 pinout, 74HC365PW,118 application, or 74HC365PW,118 equivalent, key selection criteria include 3-state enable timing (enable/disable <38 ns at +125 °C), CMOS-level input compatibility, high-impedance leakage <±10 μA at VCC = 6.0 V, and operation across -40 °C to +125 °C industrial temperature range.
Technical Context
The 74HC365PW,118 implements six independent non-inverting buffers, each with dedicated active-low 3-state output enable (OE1, OE2 controlling three channels each). Its CMOS input structure supports rail-to-rail logic thresholds (VIH = 4.2 V min at VCC = 6.0 V) and includes integrated clamp diodes enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors.
Dynamic performance is characterized by propagation delay (tpd), enable time (ten), and disable time (tdis), all specified over full temperature and voltage ranges - e.g., tpd ≤ 25 ns, ten ≤ 38 ns, tdis ≤ 38 ns at VCC = 6.0 V and Tamb = -40 °C to +125 °C - ensuring deterministic timing in synchronous bus systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V logic driving 5 V bus) |
| Output Drive | ±35 mA - sufficient to drive standard TTL loads or 50 pF transmission lines without external buffering |
| Propagation Delay | 9 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable operation up to ~50 MHz data rates in point-to-point links |
| 3-State Leakage | ±10.0 μA max at VCC = 6.0 V - ensures minimal bus contention current when outputs are disabled |
| Input Clamp Diodes | Integrated - allows safe connection of inputs to voltages > VCC using series current-limiting resistors |
| Operating Temp | -40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| ESD Rating | HBM >2000 V, CDM >1000 V - robust handling in automated assembly and field service environments |

| 11 (5Y) | Data output 5 | Fifth output; shares OE2 enable with 4Y and 6Y |
| 12 (5A) | Data input 5 | Fifth input; routed to 5Y with no inversion or delay beyond propagation spec |
| 13 (6Y) | Data output 6 | Sixth and final output; completes hex buffer set with independent enable grouping |
| 14 (6A) | Data input 6 | Sixth input; fully decoupled from other inputs except shared VCC/GND |
| 15 (OE2) | Output enable 2 | Active-low control for channels 4Y–6Y; independent timing from OE1 |
| 16 (VCC) | Supply voltage | Primary power rail; bypass capacitor (100 nF) required near pin for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation enables interoperability across 2.5 V, 3.3 V, and 5 V logic domains |
| Independent 3-state groups | Two enable inputs (OE1/OE2) partition six buffers into two isolated 3-channel groups for selective bus arbitration |
| Rail-to-rail input thresholds | VIH ≥ 4.2 V and VIL ≤ 1.8 V at VCC = 6.0 V ensure noise margin >1.2 V in 5 V systems |
| Clamp diode protection | Internal input diodes allow safe overvoltage tolerance up to VCC + 0.5 V with external current limiting |
| Low dynamic power | CPD = 40 pF per buffer - limits switching power to <1 mW per channel at 10 MHz, 5 V |
Applications
| Industrial Backplane Interface | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Isolating address/data buses between PLC CPU and modular I/O cards in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Hex buffer provides bidirectional signal conditioning and 3-state isolation to prevent bus contention during card hot-swap or firmware update. Use Value: Enables deterministic bus arbitration with <38 ns enable/disable latency at +125 °C, supporting real-time cycle times ≤100 μs. | Use Scenario: Expanding limited GPIO count on an ARM Cortex-M4 MCU to drive multiple LED indicators, relays, and sensor interfaces. IC Role / Device Role / Timing Role: Non-inverting buffer translates MCU logic levels to higher-current outputs while maintaining signal integrity across PCB traces up to 15 cm. Use Value: Delivers ±35 mA per channel without external transistors, reducing BOM count and layout area versus discrete solutions. |
| Legacy System Bus Bridging | Test Equipment Signal Routing |
Use Scenario: Interfacing modern 3.3 V FPGA I/O banks to legacy 5 V parallel printer or ISA bus peripherals. IC Role / Device Role / Timing Role: Level-shifting buffer with CMOS inputs and 5 V-tolerant outputs, leveraging clamp diodes for safe 5 V input reception. Use Value: Eliminates need for separate level translators; operates reliably at 5 V supply with VIH = 4.2 V min, ensuring >0.8 V noise margin. | Use Scenario: Configurable signal routing matrix in automated test equipment (ATE) where DUT signals must be selectively connected to measurement instruments. IC Role / Device Role / Timing Role: 3-state buffer acts as programmable switch node, controlled by FPGA to establish signal paths without loading inactive branches. Use Value: High-impedance OFF-state leakage <±10 μA prevents crosstalk between unselected channels, preserving measurement accuracy. |
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,118 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 5 V); otherwise identical pinout, timing, and drive | Required when driving from legacy 5 V TTL or LVTTL sources with marginal high-level voltage | Select for mixed-logic systems where input sources cannot guarantee CMOS-level VIH ≥ 3.15 V at VCC = 4.5 V |
| SN74LVC6T244RGYR | 6-channel, dual-OE, 3.3 V only (1.65–3.6 V), lower propagation delay (2.2 ns typ), smaller X2SON12 package | Optimized for space-constrained, low-voltage portable designs; not suitable for 5 V operation or industrial temp range | Choose for battery-powered or high-density PCBs needing sub-3 ns timing and <1 mm² footprint, but verify VCC compatibility |
Compared with 74HCT365PW,118, the 74HC365PW,118 offers superior noise immunity in 5 V systems due to higher VIH, while SN74LVC6T244RGYR enables faster, lower-power operation in 3.3 V domains at the cost of voltage and temperature range flexibility.

FAQ
What is the maximum clock frequency supported by the 74HC365PW,118?
The 74HC365PW,118 is not a clocked device but a combinational buffer; its usable data rate depends on propagation delay and load. With tpd ≤ 25 ns at +125 °C and VCC = 6.0 V, it supports clean signal transmission up to approximately 20 MHz for edge-aligned data on 50 pF loads, assuming adequate setup/hold margins in the system design.
Can 74HC365PW,118 drive a 50 Ω transmission line directly?
No - the 74HC365PW,118 is rated for ±35 mA DC output current and is intended for bus loading or short PCB trace driving, not RF impedance matching. Driving a 50 Ω line requires a dedicated line driver IC or external termination; direct connection risks waveform distortion and excessive power dissipation.
Is there a pin-compatible automotive-grade version of this part?
No - the 74HC365PW,118 is qualified for industrial temperature range (-40 °C to +125 °C) but is not AEC-Q100 qualified. Nexperia does not offer an automotive-grade variant of this specific part number; alternative automotive-qualified buffers (e.g., 74HC365-Q100) use different packaging and qualification documentation not applicable to the PW,118 variant.
How should unused inputs and outputs be handled in a design?
Unused inputs must be tied HIGH or LOW (not left floating) to prevent increased ICC and potential oscillation. Unused outputs should be disabled via OE1/OE2 and left unconnected; if enabled, they must be terminated to avoid floating states. GND and VCC pins require low-inductance decoupling (100 nF ceramic) placed within 3 mm of the package.
