MC74HC365ADG

Overview

The MC74HC365ADG is a hex buffer and line driver manufactured by onsemi, belonging to the HC logic series. It features six non-inverting buffers with three-state outputs housed in a 16-pin DIP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 20 ns, high-level output current of -7.8 mA, and low-level output current of 7.8 mA. Quiescent current is typically 4 uA at 25 °C. The component supports surface mount or through-hole installation depending on the specific variant suffix, with an operating temperature range extending from -55 °C to +125 °C.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning and bus driving applications.
• Features three-state outputs that allow multiple drivers to share a common bus without interference when disabled.
• Utilizes advanced CMOS technology to achieve high noise immunity and symmetrical output drive capabilities.

Applications

• Clock distribution networks requiring buffered signals for multiple loads.
• Data bus buffering in microprocessor-based systems to isolate memory or peripheral interfaces.
• General-purpose logic level shifting and signal regeneration in digital circuits.

Procurement Notes

Verify the package type carefully, as the 'ADG' suffix specifically denotes a 16-pin DIP (Dual In-line Package). Ensure the order matches the required mounting style, distinguishing it from surface-mount variants like 'ADR' or 'ADTR'. Confirm RoHS compliance status and check for any specific environmental declarations such as REACH material data sheets provided by onsemi for the final assembly stage.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. Compare against the HC series for standard CMOS performance or HCT series if TTL-compatible input thresholds are necessary. Consider the propagation delay and output current specifications to ensure compatibility with the load capacitance and switching speed requirements of the target application circuit.

Part Context

This part belongs to the widely adopted 74HC365 family of hex buffers. It serves as a direct functional equivalent to devices from other manufacturers such as Texas Instruments (SN74HC365) and STMicroelectronics (M74HC365), maintaining pinout and logical compatibility across the industry standard while offering onsemi's specific manufacturing characteristics and quality standards.

Replacement Considerations

Direct substitutes include SN74HC365 from Texas Instruments and M74HC365 from STMicroelectronics. These alternatives offer identical logical functions and pin configurations. Verify that the replacement device supports the same DIP-16 package and meets the required voltage and temperature specifications for the intended environment.
