74LV365DB,112

Overview

The NXP USA Inc. 74LV365DB,112 is a hex non-inverting buffer and line driver featuring 3-State outputs. It operates within a supply voltage range of 1.0V to 3.6V and accepts TTL input levels between VCC = 2.7V and VCC = 3.6V. The device utilizes a 16-pin SSOP Type II package (SOT338-1) and supports an operating temperature range from -40°C to +125°C. At VCC = 3.3V with CL = 15pF, the typical propagation delay is 9ns. Key electrical characteristics include an input capacitance of 3.5 pF and a power dissipation capacitance per buffer of 40 pF.

Feature Summary

• Hex non-inverting buffer/line driver architecture with 3-State outputs controlled by active-LOW enable inputs.
• Optimized for low-voltage applications with operation down to 1.0V and compatibility with 74HC/HCT365 pinouts.
• Low output ground bounce (VOLP < 0.8V) and undershoot (VOHV < 2V) at VCC = 3.3V.
• Bus driver output capability designed for high-speed digital signal transmission.

Applications

• High-speed data bus buffering in low-voltage systems
• Line driving for communication interfaces
• Partial power-down mode operations utilizing I_OFF circuitry

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the specific ordering suffix matches the required package type and temperature grade. Check for any product change notices (PCN) regarding manufacturing site transfers or specification updates that may affect long-term availability.

Selection Notes

Select this component when a hex buffer with 3-State control is required for low-voltage logic families. It serves as a functional replacement for 74HC/HCT365 devices in designs requiring reduced power consumption. Consider the 16-pin SSOP package constraints for PCB layout. Verify that the input voltage levels align with the source logic family, particularly noting TTL compatibility above 2.7V.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic integrated circuits manufactured by Philips Semiconductors (now NXP). The 74LV365 specifically functions as a hex buffer/line driver. It is part of a broader family of logic components designed for portable and battery-operated applications where low power and wide voltage ranges are critical design parameters.

Replacement Considerations

Direct pin-compatible substitutes include the 74LV365D (SO package) and 74LV365PW (TSSOP package). Other manufacturers producing equivalent hex buffers with 3-State outputs should be evaluated for voltage range and speed matching.

FAQ

How are the 3-State outputs controlled?

The outputs are controlled by two active-LOW output enable inputs (OE1 and OE2). A HIGH level on either OE input forces the corresponding outputs into a high-impedance OFF-state.

Is this device compatible with 5V logic inputs?

No. The device is optimized for 1.0V to 3.6V operation. While it accepts TTL input levels between 2.7V and 3.6V, it is not rated for standard 5V logic inputs without risking damage.
