SN74HC652NT Equivalent & Substitute Parts

Part Overview

The SN74HC652NT is a non-inverting transceiver IC manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. Operating across a 2V to 6V supply voltage range, this component functions as a single-element transceiver with independent control of input and output states.

The SN74HC652NT is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design requirements favor active production status and improved supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC652NT is determined by strict equivalence across the following electrical and mechanical parameters:

• Logic type: Transceiver, Non-Inverting
• Number of elements: 1
• Number of bits per element: 8
• Output type: 3-State
• Output current specifications: 7.8mA (high and low)
• Supply voltage range: 2V ~ 6V
• Operating temperature range: -40°C ~ 85°C
• Base product number: 74HC652
• RoHS and REACH compliance status

The primary difference between the main part and its substitute lies in packaging and mounting technology. The SN74HC652NT uses through-hole mounting in a 24-DIP package, while the substitute employs surface-mount technology in a 24-SOIC package. Both maintain identical electrical performance and functional specifications.

Engineering Selection Recommendations

The SN74HC652DWR serves as the direct functional equivalent to the SN74HC652NT. Both components maintain identical electrical specifications, output characteristics, and supply voltage requirements. The SN74HC652DWR holds active product status, ensuring continued availability and manufacturing support from Texas Instruments.

Selection between these parts depends on board design requirements. The SN74HC652NT accommodates through-hole assembly processes and breadboard prototyping. The SN74HC652DWR is suited for surface-mount production environments and compact PCB layouts. Both components satisfy ROHS3 compliance and REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC652DWR directly replace the SN74HC652NT in existing designs?

A: Electrical substitution is complete. The SN74HC652DWR provides identical logic function, output current, and voltage specifications. Physical substitution requires PCB redesign to accommodate the 24-SOIC surface-mount package instead of the 24-DIP through-hole package.

Q: What is the primary difference between these two parts?

A: The SN74HC652NT uses through-hole mounting (24-DIP package), while the SN74HC652DWR uses surface-mount technology (24-SOIC package). All electrical parameters remain identical.

Q: Why is the SN74HC652NT listed as obsolete?

A: The SN74HC652NT has reached end-of-life status. The SN74HC652DWR represents the active production equivalent, reflecting the industry transition from through-hole to surface-mount assembly.

Q: Are there compliance differences between these parts?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Q: What supply voltage range do these parts support?

A: Both the SN74HC652NT and SN74HC652DWR operate across 2V to 6V supply voltage with identical output current specifications of 7.8mA for both high and low states.
