74HCT365PW,118

Overview

The Nexperia 74HCT365PW,118 is a hex buffer and line driver featuring three-state outputs controlled by active-low OE1 and OE2 inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device provides non-inverting logic with high noise immunity and low power dissipation. It is housed in a 16-lead TSSOP plastic package (SOT403-1) and supports an ambient operating temperature from -40 °C to +125 °C.

Feature Summary

• Three-state outputs allow connection to bus systems via high impedance OFF-states when enabled inputs are HIGH.
• TTL-compatible input levels ensure direct interfacing with standard digital logic sources.
• Built-in input clamp diodes facilitate safe interface to voltages exceeding the supply rail using current limiting resistors.

Applications

• Bus-oriented communications
• Clock distribution
• Memory address decoding

Procurement Notes

Verify that the specific order code matches the required TSSOP16 package variant. Confirm the HCT logic family compatibility for your target voltage environment. Ensure the component meets RoHS compliance standards for your region. Check the latest datasheet revision for any updates to pin configurations or electrical characteristics before finalizing the design.

Selection Notes

Select this component when a hex buffer with three-state control is required for TTL-to-CMOS translation. The wide operating temperature range makes it suitable for industrial environments. Verify that the package dimensions align with your PCB layout constraints. Consider the propagation delay specifications relative to your system clock speeds.

Part Context

This part belongs to the 74HCT series of CMOS logic devices manufactured by Nexperia. It shares functional similarities with the 74HC365 but utilizes different input threshold levels optimized for 5 V operation. The PW suffix indicates the specific thin shrink small outline package used for surface mount assembly.

Replacement Considerations

The 74HCT365PW,118 is functionally equivalent to other manufacturers' 74HCT365 variants in TSSOP16 packages. Cross-reference pinouts and electrical limits carefully when substituting with parts from different suppliers.

FAQ

How are the three-state outputs controlled?

The outputs enter a high-impedance OFF-state when either OE1 or OE2 input is driven HIGH. They remain active only when both enable inputs are LOW.

What is the maximum supply voltage for this device?

The recommended operating conditions specify a maximum supply voltage of 5.5 V for the 74HCT365 variant.
