Product details
Overview
CD74HC365M96E4 from Texas Instruments is a high-speed CMOS hex non-inverting three-state buffer with dual active-low output enables (OE1, OE2), 2–6 V supply operation, 8 ns typical propagation delay at 5 V/15 pF, ±25 mA output drive per channel, and -55°C to +125°C operating temperature range - used for bidirectional bus interfacing in industrial control backplanes.
For engineers reviewing the CD74HC365M96E4 datasheet, CD74HC365M96E4 pinout, CD74HC365M96E4 application, or CD74HC365M96E4 equivalent, key selection criteria include its non-inverting logic function, SOIC-16 package, three-state bus driver capability, LSTTL-compatible fanout (15 loads), and HC-family voltage flexibility (2–6 V).
Technical Context
The CD74HC365M96E4 implements six independent non-inverting buffers, each with high-current CMOS outputs capable of driving 15 LSTTL loads. Its dual active-low enable inputs (OE1, OE2) are internally NORed to simultaneously place all six outputs in high-impedance state when either is asserted.
It operates across 2–6 V with rail-to-rail input thresholds (VIH = 1.5 V min at 2 V, 4.2 V min at 6 V), exhibits balanced tPLH/tPHL propagation delays, and delivers <0.1 V VOL and >4.4 V VOH under TTL loads at 4.5 V - enabling direct interface with legacy LSTTL systems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex non-inverting three-state buffer with dual NORed output enables |
| Supply Voltage Range | 2 V to 6 V - supports mixed-voltage system integration and battery-powered designs |
| Propagation Delay (tPLH/tPHL) | 8 ns typical at VCC = 5 V, CL = 15 pF - ensures timing compliance in 25 MHz+ bus applications |
| Output Drive Capability | ±25 mA per output - sustains signal integrity driving 15 LSTTL loads or 50 pF bus capacitance |
| Operating Temperature | -55°C to +125°C - qualified for extended industrial, aerospace, and under-hood automotive environments |
| Input Thresholds (VCC = 5 V) | VIH = 3.15 V min, VIL = 1.35 V max - provides 30% noise margin against both high and low states |
| Three-State Leakage (IOZ) | ±5 µA max over full temperature range - minimizes standby current in high-density bus architectures |
Pinout & Package
CD74HC365M96E4 is housed in a 16-pin SOIC (D) package measuring 9.90 mm × 3.90 mm, with standard 1.27 mm pitch and RoHS-compliant NiPdAu lead finish. It conforms to JEDEC MS-012, Level-1 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low output enable inputs; internally NORed - assertion places all Y outputs in high-Z |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Non-inverting data inputs - directly connected to upstream logic sources or microcontroller GPIO |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Buffered non-inverting outputs - drive bidirectional data buses, address lines, or peripheral interfaces |
| 8 | GND | Ground reference for all internal circuitry and output drivers |
| 16 | VCC | Positive supply rail - must be bypassed with 0.1 µF ceramic capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| High-current bus driver outputs | ±25 mA per channel enables robust driving of 15 LSTTL loads or 50 pF capacitive buses |
| Wide supply voltage range (2–6 V) | Eliminates need for level translators in mixed-voltage systems and extends battery life in portable equipment |
| Balanced propagation delay & transition times | Minimizes skew between channels and reduces EMI in synchronous bus applications |
| Low quiescent current (ICC ≤ 160 µA) | Reduces system power budget in always-on industrial controllers and remote sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting three-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC365N | Same logic function and pinout; PDIP-16 package only; rated for -40°C to +85°C commercial temp range | Limited to commercial-grade environments; lacks extended temperature qualification | Select SN74HC365N only for cost-sensitive, non-industrial applications where ambient temperature stays below 85°C |
| CD74HCT365M96 | Pin-compatible HCT variant; 4.5–5.5 V operation only; LSTTL-input compatible (VIH = 2 V min, VIL = 0.8 V max) | Requires stable 5 V supply; optimized for legacy TTL system integration, not wide-voltage flexibility | Choose CD74HCT365M96 when interfacing directly with 5 V LSTTL logic families and no mixed-supply operation is needed |
Compared with SN74HC365N, CD74HC365M96E4 offers extended temperature support and SOIC packaging for higher density layouts; compared with CD74HCT365M96, it provides broader supply range and CMOS input thresholds - making CD74HC365M96E4 the preferred choice for ruggedized, multi-rail embedded systems.

FAQ
What is the logic function and output behavior of the CD74HC365M96E4?
The CD74HC365M96E4 is a hex non-inverting three-state buffer. Each of its six channels passes input A to output Y unchanged when both OE1 and OE2 are low; if either OE1 or OE2 is high, the corresponding Y output enters high-impedance state. This behavior is confirmed in the device functional modes table and logic diagram of the official TI datasheet SCHS180D.
Does the CD74HC365M96E4 support 3.3 V operation?
Yes, the CD74HC365M96E4 fully supports 3.3 V operation. As an HC-type device, its specified supply range is 2 V to 6 V, and electrical characteristics including VIH (1.8 V min), VIL (0.99 V max), VOH (>3.2 V), and VOL (<0.1 V) are guaranteed at VCC = 3.3 V across the full -55°C to +125°C temperature range per Section 5.4 of the TI datasheet.
What is the maximum output current per pin for the CD74HC365M96E4?
The CD74HC365M96E4 supports ±25 mA DC output source/sink current per output pin (Y1–Y6), as specified in Section 5.1 Absolute Maximum Ratings and validated in switching-characteristics load conditions. This rating applies across the full operating temperature range and enables direct driving of 15 LSTTL loads or 50 pF bus capacitance.
How are the two output enable inputs (OE1 and OE2) configured in the CD74HC365M96E4?
In the CD74HC365M96E4, OE1 (pin 1) and OE2 (pin 15) are internally NORed - meaning all six outputs go to high-impedance whenever either input is driven high. This dual-enable architecture provides redundancy and flexible bus control, and is explicitly documented in Section 7.3 Device Functional Modes and Table 7-1 of the TI datasheet.
Is the CD74HC365M96E4 pin-compatible with the CD74HCT365M96?
Yes, the CD74HC365M96E4 is pin-compatible with CD74HCT365M96. Both devices share identical SOIC-16 (D) package dimensions, pin numbering, and pin functions (OE1, A1–A6, Y1–Y6, GND, VCC). However, they differ in supply range (HC: 2–6 V; HCT: 4.5–5.5 V) and input threshold compatibility - confirmed in TI's Package Option Addendum and functional descriptions.
