Applications
The SN74HC365N is widely used in microcontroller-based systems for driving data buses, address buses, and control lines where bus isolation or signal buffering is required. It is commonly found in embedded systems, industrial controllers, and legacy TTL-compatible designs that need CMOS-level buffers with tristate capability. Its through-hole DIP packaging makes it a popular choice for prototyping, education boards, and repair of older electronic equipment.

Frequently Asked Questions
What is the maximum supply voltage and operating frequency for the SN74HC365N?
The SN74HC365N operates from a supply voltage of 2V to 6V (typical 5V). At VCC = 5V, it supports propagation delays of approximately 7–10 ns, enabling operation at frequencies well above 50 MHz, making it suitable for high-speed digital bus driving applications.
How do the dual enable inputs (G1 and G2) work on the SN74HC365N?
The SN74HC365N has two active-low output enable pins, G1 and G2. Both must be LOW simultaneously to enable all six buffers and drive the outputs. If either enable pin is HIGH, all outputs enter a high-impedance (3-state) condition, effectively disconnecting the device from the bus.
What are typical applications for the SN74HC365N hex bus driver?
Typical applications include data bus buffering in 8-bit microcontroller systems, address line driving in memory interfaces, signal level shifting between 3.3V and 5V logic domains, and bus isolation in industrial automation equipment. Its 150pF load capacitance tolerance suits moderately loaded PCB traces.
Is the SN74HC365N compatible with TTL logic levels?
Yes, the SN74HC365N is fully TTL-compatible when powered at 5V. Its input thresholds (VIH ≥ 3.15V, VIL ≤ 1.35V at VCC = 5V) and output drive levels are compatible with standard 74LS and 74HCT devices, allowing seamless integration in mixed-logic legacy and modern designs.
What is the difference between SN74HC365N and SN74HC244N?
Both are octal/hex buffers with 3-state outputs, but the SN74HC365N is a hex (6-bit) buffer in a 16-pin DIP with dual enable control, while the SN74HC244N is an octal (8-bit) buffer in a 20-pin package with two separate 4-bit enable groups. Choose SN74HC365N when 6-bit width or DIP-16 form factor is required.
