SN74HC365N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC365N is a hex buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features true, non-inverting outputs and dual-gated output-enable inputs (OE1 and OE2). When either enable pin is high, the outputs enter a high-impedance state. At 5V, it provides ±6-mA output drive capability, allowing it to drive bus lines or up to 15 LSTTL loads. Typical propagation delay is 10 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and status before procurement. The SN74HC365N in PDIP-16 packaging is listed as NRND (Not Recommended for New Designs) in the official TI Package Option Addendum. Confirm availability of alternative packages such as SOIC or TSSOP variants if long-term production support is required.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring hex buffering with tri-state control. Ensure the application voltage falls between 2 V and 6 V. Verify that the input transition rise/fall times comply with recommended operating conditions to maintain specified switching characteristics. Unused inputs must be tied to logic high or low to prevent undefined states.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HC365 family of hex buffers and line drivers. It is designed to improve performance and density in digital systems. The 'HC' designation indicates High-speed CMOS technology. Other available packages include SOIC, SOP, and TSSOP, offering flexibility for different board space constraints.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The outputs are controlled by two output-enable pins, OE1 and OE2. If either pin is set to a high state, all outputs enter a high-impedance mode. Data passes from inputs to outputs only when both enable pins are low.

What is the maximum output current?

The device can provide ±6 mA of output drive current at 5 V, which allows it to drive up to 15 LSTTL loads.
