Product details
Overview
74HCT365D,652 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs, operating from 4.5 V to 5.5 V, delivering ±6 mA output drive at VCC = 4.5 V, and specified for -40 °C to +125 °C industrial temperature range in SO16 (SOT109-1) package. It enables bidirectional bus isolation in microcontroller peripheral interfaces and legacy parallel data paths.
For engineers reviewing the 74HCT365D,652 datasheet, 74HCT365D,652 pinout, 74HCT365D,652 application, or 74HCT365D,652 equivalent, key selection criteria include TTL-level input compatibility, dual active-low output enable control (OE1/OE2), guaranteed 3-state leakage < ±10 μA at 5.5 V, propagation delay ≤38 ns at 4.5 V over full temperature range, and SO16 package thermal derating (12.4 mW/K above 110 °C).
Technical Context
This device implements six independent non-inverting buffer channels, each with separate input and output terminals, controlled by two shared active-low 3-state enable inputs (OE1 on Pin 1, OE2 on Pin 15). All outputs enter high-impedance state when either OE1 or OE2 is HIGH, supporting flexible bus arbitration.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Static characteristics confirm VIH = 2.0 V min and VIL = 0.8 V max at VCC = 4.5–5.5 V, ensuring robust noise immunity against TTL logic families.

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 |
|---|---|---|---|

FAQ
What is the maximum output current per channel for 74HCT365D,652?
The device delivers ±6.0 mA DC output current per channel at VCC = 4.5 V, as verified under recommended operating conditions with VOH ≥ 3.7 V and VOL ≤ 0.4 V across -40 °C to +125 °C. This rating supports driving standard 50 pF loads and up to 10 LS-TTL inputs simultaneously without violating voltage thresholds.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 (Pin 1) and OE2 (Pin 15) can be connected to a common control signal, enabling all six outputs simultaneously. Doing so reduces control pin count but eliminates independent segmentation. The inputs are electrically identical and share no internal coupling, so no additional buffering or pull-up is required.
Is 74HCT365D,652 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, this part is not AEC-Q100 qualified and lacks automotive-specific stress testing, failure analysis reporting, or PPAP documentation. It is intended for industrial and commercial use; automotive designs require explicitly qualified variants such as 74HCT365DB,118 (discontinued) or newer automotive-grade logic families.
How does input clamping affect interfacing with 12 V signals?
Clamp diodes to VCC and GND allow safe interface to voltages up to VCC + 0.5 V when used with a series current-limiting resistor. For 12 V signals, a minimum 1.8 kΩ resistor limits IIK to ≤20 mA at VCC = 4.5 V, protecting inputs while preserving logic thresholds - confirmed per Section 5.2 and Table 4 of the datasheet.
