74HCT366D,652

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74HCT366D,652 is a hex inverting buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (OE1 and OE2). It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device provides high noise immunity and low power dissipation, with inputs equipped with clamp diodes for interfacing voltages exceeding VCC. It is housed in an SO16 plastic small outline package (SOT109-1) and supports an operating temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm RoHS compliance and REACH registration details directly with the manufacturer or authorized distributors prior to procurement. Ensure design-in compatibility with existing system voltage requirements and thermal constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level interface compatibility is required alongside CMOS performance characteristics. The 74HCT variant ensures direct interfacing with standard TTL logic outputs without level shifting. Verify that the required propagation delay and drive current capabilities meet the specific application timing and load requirements defined in the datasheet.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74HCT series, which combines the high noise immunity and low power consumption of CMOS technology with the fast switching speeds and standard logic levels of TTL. The 74HCT366 specifically functions as a hex buffer with invert and three-state capability, widely used in digital logic designs requiring signal inversion and bus isolation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the 74HC366D variants, though these require CMOS-level input signals rather than TTL levels. Other manufacturers producing JEDEC-compliant 74HCT366 devices may serve as substitutes if pinout and electrical specifications are verified.
