Product details
Overview
74HC365D,653 from Nexperia is a hex non-inverting 3-state buffer/line driver in SO16 package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, ±35 mA output drive, and guaranteed operation from −40 °C to +125 °C. It enables bidirectional bus isolation in industrial control I/O expansion and microcontroller peripheral interfacing.
For engineers reviewing the 74HC365D,653 datasheet, 74HC365D,653 pinout, 74HC365D,653 application, or 74HC365D,653 equivalent, this device supports high-noise-immunity digital signal buffering with precise enable-controlled tri-state outputs, low static current (≤160 μA at VCC = 6.0 V), and fast propagation delay (9–25 ns depending on VCC and temperature).
Technical Context
The 74HC365D,653 implements six independent non-inverting buffers, each with dedicated active-low 3-state enable control via two shared OE inputs (OE1 for channels 1–3, OE2 for channels 4–6). Its CMOS input structure includes clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), delivers VOH ≥3.98 V and VOL ≤0.26 V at VCC = 4.5 V/IO = ±6 mA, and exhibits latch-up immunity >100 mA per JESD78 Class II Level B.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT365D,653 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and drive | Better suited for legacy 5 V TTL systems where input thresholds must match 2.0 V logic families | Select when interfacing with older 74LS or 74F logic; not recommended for pure CMOS systems due to higher input current |
| SN74LVC365APWR | 3.3 V only (1.65–3.6 V), lower VCC max, but faster (tpd = 5.2 ns typ @ 3.3 V), smaller TSSOP16 package | Optimized for modern low-voltage portable electronics; lacks 5 V tolerance and extended temperature range | Choose for space-constrained, battery-powered designs requiring <6 ns delay and 3.3 V compatibility only |
Compared with 74HCT365D,653 and SN74LVC365APWR, the 74HC365D,653 uniquely balances wide voltage operation (2–6 V), industrial temperature support (−40 to +125 °C), and CMOS input compatibility-making it the default choice for mixed-voltage, high-reliability embedded control.

FAQ
Can 74HC365D,653 drive a 50 pF load at 10 MHz without signal degradation?
Yes. With typical propagation delay of 9 ns at VCC = 6.0 V and transition time of 4 ns, the device easily handles 10 MHz square waves into 50 pF loads. Its 40 pF power dissipation capacitance (CPD) and ±35 mA drive ensure minimal rise/fall time distortion and adequate timing margin for synchronous interfaces.
What happens if OE1 and OE2 are both held HIGH?
All six outputs (1Y–6Y) enter high-impedance (Z) state simultaneously, effectively disconnecting all buffered signals from the bus. This condition draws only ≤160 μA total supply current at VCC = 6.0 V and Tamb = +125 °C, making it ideal for low-power standby modes.
Is the SO16 package RoHS-compliant and lead-free?
Yes. The 74HC365D,653 in SOT109-1 (SO16) package meets RoHS Directive 2011/65/EU and is fully lead-free, with matte tin lead finish and halogen-free molding compound, certified per Nexperia's material declarations and IPC-1752A reporting.
How does input clamping affect connection to 12 V sensors?
Clamp diodes allow safe interface to 12 V signals when a series current-limiting resistor (e.g., 10 kΩ) is used: VI is clamped to VCC + 0.5 V, limiting input current to ≤20 mA. This avoids external protection components while preserving logic-level compatibility at the buffer input.
