Product details
Overview
CD74HC365M96 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 operation, 8 ns typical propagation delay at 5 V/15 pF, ±25 mA output drive, and -55°C to +125°C operating range - used in bus interface and data routing applications in industrial control and instrumentation systems.
For engineers reviewing the CD74HC365M96 datasheet, CD74HC365M96 pinout, CD74HC365M96 application, or CD74HC365M96 equivalent, key selection criteria include its SOIC-16 package, HC logic family voltage flexibility, three-state bus driving capability, LSTTL-compatible fanout, and thermal robustness across extended temperature ranges.
Technical Context
The CD74HC365M96 implements six independent non-inverting buffer channels, each controlled by a shared NOR logic of OE1 and OE2 to place all outputs simultaneously into high-impedance state. Its silicon-gate CMOS process delivers low static current (≤160 µA over temperature) while maintaining TTL-compatible speed and drive strength.
It operates across 2–6 V supply, supports 15 LSTTL loads per output, and features balanced tPLH/tPHL transition times (≤27 ns max at 6 V/15 pF), enabling clean signal integrity in bidirectional bus architectures without external pull-ups or level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | HC (High-Speed CMOS), 2–6 V supply compatible |
| Propagation Delay | 8 ns typical at VCC = 5 V, CL = 15 pF - ensures sub-10 ns timing margin for 50 MHz bus clocking |
| Output Drive | ±25 mA per output - sufficient to drive 15 LSTTL loads or moderate PCB trace capacitance |
| Operating Temp | -55°C to +125°C - qualified for harsh industrial and under-hood automotive environments |
| Three-State Leakage | ±10 µA max at -55°C to +125°C - maintains bus integrity during disable without excessive power loss |
| Input Voltage Thresholds | VIH = 1.8 V, VIL = 0.5 V at VCC = 6 V - provides 30% noise margin for reliable logic-level interpretation |
| Power Dissipation Cap | 40 pF - enables accurate dynamic power estimation (PD = VCC² × fi × (CPD + CI)) |
Pinout & Package
CD74HC365M96 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, rated MSL Level-1 (unlimited floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low enable inputs; NOR logic controls all six outputs' three-state behavior |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Non-inverting input terminals for each of six buffer channels |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Corresponding non-inverting buffered outputs; high-impedance when OE1=OE2=H |
| 8 | GND | Ground reference for logic and output stages; must be low-impedance connection |
| 16 | VCC | Positive supply rail; requires local 0.1 µF bypass capacitor per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2–6 V operation enables direct interfacing with 3.3 V and 5 V systems without level translation |
| Bus-Driver Output Strength | ±25 mA drive supports termination-resistor-loaded buses and long traces up to 15 LSTTL loads |
| Low Quiescent Current | ≤160 µA max ICC over full temperature range - critical for low-power standby modes |
| High Noise Immunity | 30% VIH/VIL noise margin at VCC = 5 V reduces susceptibility to EMI in noisy industrial settings |
| Thermal Robustness | Rated for -55°C to +125°C ambient - validated for use in sealed enclosures and uncooled control cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC365N | Same HC logic, identical pinout, but PDIP-16 package and narrower temp range (-40°C to +85°C) | Suitable only for commercial-grade board-level prototyping, not extended-temp production | Select when cost-sensitive, non-industrial designs require through-hole assembly and lower thermal requirements |
| CD74HCT365M96 | HCT variant: 4.5–5.5 V only, LSTTL-input compatible (VIL ≤ 0.8 V), same SOIC-16 package and marking | Required where legacy 5 V TTL logic coexists and strict input threshold matching is mandatory | Choose when interfacing directly with 74LS-series devices and supply rails are tightly regulated at 5 V ±5% |
Compared with SN74HC365N, CD74HC365M96 offers wider temperature tolerance and surface-mount readiness; versus CD74HCT365M96, it provides broader supply flexibility and higher noise immunity at the cost of TTL input compatibility.

FAQ
What is the maximum supply voltage rating for CD74HC365M96?
The CD74HC365M96 has an absolute maximum supply voltage (VCC) of 7 V, but its recommended operating range is 2 V to 6 V. Operation above 6 V risks exceeding electrical specifications and may degrade long-term reliability. TI specifies 6 V as the upper limit for guaranteed performance across all parameters including propagation delay, output drive, and leakage current.
Does CD74HC365M96 support true bidirectional data flow?
No, CD74HC365M96 is a unidirectional non-inverting buffer - signals flow only from A inputs to Y outputs. It does not implement internal direction control or bus transceiver functionality. For bidirectional operation, separate transmit/receive buffers or dedicated transceivers like the SN74LVC245A are required. The device's three-state outputs enable bus sharing but not reverse signal path.
What is the purpose of the dual OE pins (OE1 and OE2) on CD74HC365M96?
The CD74HC365M96 uses OE1 and OE2 as active-low enables whose logic is internally NORed: all six outputs enter high-impedance state only when both OE1 and OE2 are high. This architecture allows flexible control - either pin can independently disable the entire device, or they can be tied together for single-enable operation. It prevents partial enable states that could cause bus contention.
Can CD74HC365M96 drive a 50 pF load within its specified propagation delay?
Yes, CD74HC365M96 is characterized for CL = 50 pF loads: at VCC = 6 V, tPLH/tPHL is 27 ns max over -55°C to +125°C. At 5 V, the datasheet specifies 32 ns max under same conditions. These values include test fixture contributions, confirming reliable timing margin for PCB traces and connectors adding up to 50 pF total capacitive load without derating.
Is CD74HC365M96 pin-compatible with CD74HC366M96?
No, CD74HC365M96 and CD74HC366M96 share the same SOIC-16 package and pinout, but differ functionally: CD74HC365M96 is non-inverting, while CD74HC366M96 is inverting. Their logic diagrams and truth tables are complementary. Swapping them without circuit review will invert all six data paths, potentially causing protocol failures or incorrect sensor readings in time-critical applications.
