Product details
Overview
74HCT365D,653 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs, designed for bus interface and signal isolation in digital systems. It features two independent 3-state enable inputs (OE1, OE2), operates from 4.5 V to 5.5 V, delivers ±6 mA output drive at VCC = 4.5 V, and supports industrial temperature range (−40 °C to +125 °C) in SO16 package.
For engineers reviewing the 74HCT365D,653 datasheet, 74HCT365D,653 pinout, 74HCT365D,653 application, or 74HCT365D,653 equivalent, this device is selected for bidirectional bus buffering, address/data line driving, and logic-level translation where TTL input thresholds and CMOS output swing are required under stable supply conditions.
Technical Context
The 74HCT365D,653 implements six independent non-inverting buffers, each with dedicated input and output terminals, grouped into two 3-channel blocks sharing OE1 (pins 1, 2, 3) and OE2 (pins 15, 14, 13). Each output enters high-impedance state when its associated OE is HIGH (active LOW control).
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Static characteristics confirm TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail CMOS-compatible output voltage swing (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±6 mA).
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 logic systems. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Guarantees reliable recognition of TTL logic levels without level-shifting circuitry. |
| Output Drive | ±6.0 mA at VCC = 4.5 V - Sufficient to drive 10 LSTTL loads or moderate capacitive buses (≤50 pF). |
| Propagation Delay | 14–38 ns (nA to nY) - Enables operation up to ~20 MHz in low-load configurations. |
| 3-State Enable Time | 18–53 ns (OE to output valid) - Supports fast bus arbitration and multiplexed data routing. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial control environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces risk of handling damage during PCB assembly and field service. |
Pinout & Package
74HCT365D,653 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Output enable input 1 | Active LOW control for outputs 1Y, 2Y, 3Y - drives all three to high-Z when HIGH. |
| 2 (1A) | Data input 1 | Non-inverting input for first buffer channel - directly connected to 1Y output. |
| 3 (1Y) | Data output 1 | CMOS-output buffer stage - sinks or sources up to 6 mA with rail-aligned VOH/VOL. |
| 4 (2A) | Data input 2 | Non-inverting input for second buffer channel - paired with 2Y (pin 5). |
| 5 (2Y) | Data output 2 | Independent buffered output - electrically isolated from other channels except shared VCC/GND. |
| 6 (3A) | Data input 3 | Non-inverting input for third buffer channel - controlled by OE1 (pin 1). |
| 7 (3Y) | Data output 3 | Third output in OE1 group - enables 3-channel parallel bus segment control. |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O - must be low-impedance for noise immunity. |
| 9 (4Y) | Data output 4 | First output in OE2 group - active only when OE2 (pin 15) is LOW. |
| 10 (4A) | Data input 4 | Non-inverting input for fourth buffer - matches 4Y (pin 9) with identical timing. |
| 11 (5Y) | Data output 5 | Fifth output - shares OE2 control with pins 14 (5A) and 13 (6Y). |
| 12 (5A) | Data input 5 | Input for fifth buffer - electrically identical to 1A–3A but gated by OE2. |
| 13 (6Y) | Data output 6 | Sixth and final output - completes full hex-buffer capability with dual-OE flexibility. |
| 14 (6A) | Data input 6 | Input for sixth buffer - allows independent control of two 3-bit groups on shared bus. |
| 15 (OE2) | Output enable input 2 | Active LOW control for outputs 4Y, 5Y, 6Y - enables interleaved or mirrored bus access. |
| 16 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail - decoupling capacitor (100 nF) recommended near 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 need for external level shifters when interfacing with legacy 5 V TTL. |
| Dual 3-state enable control | Separate OE1 (pins 1,2,3) and OE2 (pins 15,14,13) - allows partitioned bus management without external gating logic. |
| High noise immunity | Typical noise margin > 0.8 V at VCC = 5 V - ensures robust operation in electrically noisy industrial environments. |
| Wide temperature range | Specified from −40 °C to +125 °C - supports deployment in engine control units and motor drive inverters. |
| Low static power consumption | ICC ≤ 160 μA at VCC = 5.5 V, Tamb = +125 °C - reduces thermal load in densely packed logic assemblies. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

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 |
|---|---|---|---|
| 74HCT244D,653 | Octal (8-channel), single OE input, no dual-OE grouping | Better suited for full-bus drivers where unified enable suffices; lacks independent 3+3 segmentation. | Select when needing higher channel count and simpler control, not split-bus arbitration. |
| SN74HCT365N | DIP-16 package, same electrical specs, wider lead pitch (2.54 mm) | Preferred for through-hole prototyping or legacy board rework; incompatible with SO16 footprint. | Choose for breadboard evaluation or replacement in existing DIP-based designs. |
Compared with 74HCT244D,653 and SN74HCT365N, the 74HCT365D,653 uniquely balances dual-OE flexibility, SO16 surface-mount compatibility, and proven industrial temperature resilience - making it optimal for new designs requiring selective 3-channel bus control in compact layouts.

FAQ
What is the maximum capacitive load the 74HCT365D,653 can drive while maintaining specified timing?
The device is characterized with CL = 50 pF in dynamic testing (Table 9), and propagation delay remains within spec up to 50 pF at VCC = 4.5 V and Tamb = +125 °C. Driving >50 pF increases tpd and tt nonlinearly; for loads >75 pF, derating or adding series termination is recommended to maintain signal integrity.
Can 74HCT365D,653 be used with a 3.3 V microcontroller I/O?
No - its TTL-compatible inputs require VIH ≥ 2.0 V, but the 74HCT365D,653 must be powered at 4.5–5.5 V to meet that threshold. A 3.3 V supply yields VIH min = 1.5 V (per 74HC365 specs), which is insufficient for guaranteed TTL recognition. Use 74LVC365 or level translators instead.
Is there any difference in DC characteristics between the SO16 (74HCT365D) and TSSOP16 (74HCT365PW) packages?
No - Nexperia specifies identical static parameters (VOH, VOL, VIH, VIL, ICC) across both packages. Thermal resistance differs (SO16: 12.4 mW/K above 110 °C; TSSOP16: 8.5 mW/K above 91 °C), but DC electrical behavior is fully interchangeable at same VCC and temperature.
How does the input clamping diode affect interface design with voltages above VCC?
The integrated clamp diodes allow safe connection of inputs to voltages up to VCC + 0.5 V when current is limited to ±20 mA (Table 4). For example, with VCC = 5 V, a 12 V signal may be applied via a 390 Ω resistor (7 V / 390 Ω ≈ 18 mA), protecting the input without external components.
