Product details
Overview
SN74HCS365PWR from Texas Instruments is a hex noninverting buffer/line driver with Schmitt-trigger inputs and dual 3-state outputs (OE1/OE2), operating from 2 V to 6 V supply, delivering ±7.8-mA drive at 6 V, with –40°C to +125°C temperature range - used for noise-immune signal conditioning in industrial control I/O interfaces.
For engineers reviewing the SN74HCS365PWR datasheet, SN74HCS365PWR pinout, SN74HCS365PWR application, or SN74HCS365PWR equivalent, key selection criteria include Schmitt-trigger hysteresis (ΔVT ≥ 0.6 V at 6 V), 3-state output timing (tdis ≤ 16 ns at 6 V), low ICC (≤ 2 µA), and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The SN74HCS365PWR implements six independent CMOS buffers with Schmitt-trigger input thresholds (VT+ = 2.1–4.2 V, VT− = 1.2–3.0 V at 6 V) enabling robust operation with slow-rising or noisy signals. Its dual active-low output enables (OE1/OE2) allow grouped 3-state control of three-channel subsets.
Each channel features balanced push-pull outputs capable of sourcing/sinking up to ±7.8 mA at 6 V while maintaining VOL ≤ 0.33 V and VOH ≥ 5.4 V. Propagation delay is 4–11 ns across 2–6 V supply, with disable time as low as 8 ns at 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2 V to 6 V - supports single-supply operation across 1.8-V, 3.3-V, and 5-V logic domains without level shifters. |
| Input hysteresis (ΔVT) | 0.6 V min at 6 V - rejects noise spikes up to ±300 mV peak-to-peak on slow-switching lines like mechanical switch debouncing. |
| Output drive | ±7.8 mA at 6 V - drives 50-pF loads with <11 ns propagation delay while maintaining VOL ≤ 0.33 V and VOH ≥ 5.4 V. |
| Supply current (ICC) | ≤ 2 µA max at 6 V - enables ultra-low-power standby in battery-backed or energy-harvesting systems. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, motor control, and industrial PLC environments. |
| ESD rating | ±4000 V HBM - withstands handling and board-level ESD events without external protection diodes. |
| Propagation delay (tpd) | 4 ns typ at 6 V - ensures timing-critical bus buffering with sub-5-ns channel-to-channel skew. |
Pinout & Package
TSSOP-16 package (5.00 mm × 4.40 mm body size), 0.65-mm lead pitch, thin-profile surface-mount construction optimized for automated assembly and thermal performance (RθJA = 141.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low 3-state enable inputs - either high disables all six outputs into high-impedance mode; allows split-bus control. |
| 2, 4, 6, 10, 12, 14 | A1–A6 | Independent Schmitt-trigger input channels - tolerate slow edges and reject noise without external RC filtering. |
| 3, 5, 7, 9, 11, 13 | Y1–Y6 | Noninverting buffered outputs with 3-state capability - support bidirectional bus driving when paired with complementary devices. |
| 8 | GND | Ground reference - must be low-impedance connection; decoupling capacitor required between Pin 16 and Pin 8. |
| 16 | VCC | Positive supply - requires 0.1-µF ceramic bypass capacitor placed adjacent to Pin 16 for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides ≥0.6 V hysteresis at 6 V to eliminate chatter from mechanical switches or long traces with reflections. |
| Dual 3-state enables | OE1 and OE2 independently gate two groups of three channels - enables flexible bus arbitration in multi-peripheral systems. |
| Low ICC leakage | ≤2 µA max supply current at 6 V - reduces quiescent power in always-on monitoring circuits by >99% vs. standard TTL. |
| Wide VCC range | 2–6 V operation - eliminates need for separate voltage regulators when interfacing mixed-voltage subsystems (e.g., 3.3-V MCU to 5-V sensor). |
| High noise immunity | ±4000-V HBM ESD rating and input clamp diodes - sustains reliability in electrically noisy factory-floor environments. |
Applications
| Industrial Sensor Interface | PLC Digital I/O Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCS367PWR | Inverting output polarity; otherwise identical Schmitt inputs, 3-state control, and electrical specs. | Required where signal inversion is needed in bus drivers or logic complementation stages. | Select SN74HCS367PWR only when inverted Y = NOT(A) behavior is explicitly required - not a drop-in replacement. |
| SN74LVTH16244DGGR | 16-bit, non-Schmitt, LVT logic; higher drive (±24 mA), but no hysteresis and narrower VCC (2.7–3.6 V). | Suitable for high-speed memory address buses where noise immunity is less critical than speed/density. | Choose SN74LVTH16244DGGR for 16-bit parallel paths at >100 MHz; avoid for slow/noisy signals due to missing Schmitt architecture. |
Compared with SN74HCS365PWR, SN74HCS367PWR provides identical noise rejection and drive but inverts logic; SN74LVTH16244DGGR offers greater channel count and speed but lacks Schmitt inputs and wide-VCC flexibility - making SN74HCS365PWR optimal for mixed-signal industrial edge nodes requiring robustness over raw bandwidth.

FAQ
What is the maximum capacitive load SN74HCS365PWR can drive while meeting all datasheet specifications?
The SN74HCS365PWR is characterized for CL = 50 pF in switching characteristics tables. While larger loads may function, timing parameters (tpd, ten, tdis) and output voltage levels (VOH/VOL) are only guaranteed up to 50 pF. Exceeding this value increases propagation delay and may degrade noise margins - SN74HCS365PWR should be used with ≤50-pF loads for full spec compliance.
Does SN74HCS365PWR support true 3-state operation with both OE1 and OE2 asserted simultaneously?
Yes. The SN74HCS365PWR enters high-impedance state whenever either OE1 or OE2 is high - including when both are high. This dual-enable architecture allows flexible bus control: OE1 can manage channels 1–3 while OE2 manages channels 4–6, or both can be tied together for unified 3-state control of all six outputs.
Can unused inputs on SN74HCS365PWR be left floating?
No. Unused inputs on SN74HCS365PWR must be terminated to VCC or GND - either directly or via pull-up/pull-down resistors (e.g., 10 kΩ). Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation. Schmitt-trigger inputs do not eliminate this requirement; they only improve noise tolerance of driven inputs.
What is the minimum input transition rate supported by SN74HCS365PWR?
The SN74HCS365PWR has no minimum input transition rate due to its Schmitt-trigger inputs. It reliably accepts arbitrarily slow edges - such as those from thermistors, potentiometers, or mechanical switches - without metastability or excessive dynamic current. This makes SN74HCS365PWR ideal for debounce and slow-signal conditioning applications.
Is SN74HCS365PWR pin-compatible with legacy 74HC365 devices?
No. Although functionally similar, SN74HCS365PWR uses a different internal architecture (Schmitt-trigger inputs, lower ICC, improved ESD) and shares the same TSSOP-16 pinout as SN74HC365PWR - but electrical differences (e.g., VT thresholds, ICC, drive strength) require validation in the target application. SN74HCS365PWR is not a direct drop-in replacement without design review.
