74HCT153N,652 Equivalent & Substitute Parts

Part Overview

The 74HCT153N,652 is a dual 4:1 multiplexer logic integrated circuit manufactured by NXP Semiconductors in a 16-DIP through-hole package. This component functions as a data selector, routing one of four input signals to a single output based on binary control inputs. The part is classified as obsolete, making equivalent substitute components necessary for ongoing production, maintenance, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT153N,652 is determined by the following critical parameters:

• Functional equivalence: Dual 4:1 multiplexer circuit configuration
• Electrical compatibility: Single supply voltage range 4.5V ~ 5.5V, output current 4mA / 4mA
• Package compatibility: 16-DIP (0.300", 7.62mm) through-hole mounting
• Series compatibility: 74HCT logic family
• Temperature range: Operating range must support the application requirements

The CD74HCT153E from Harris Corporation meets these substitution criteria, providing identical functional and electrical characteristics within the same package form factor.

Parameter Comparison

Engineering Selection Recommendations

74HCT153N,652 (NXP Semiconductors)

• RoHS3 compliant
• Operating temperature range: -40°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

CD74HCT153E (Harris Corporation)

• RoHS non-compliant
• Operating temperature range: -55°C ~ 125°C (extended low-temperature capability)
• Packaging: Tube

Selection between these parts depends on regulatory compliance requirements. The 74HCT153N,652 is suitable for applications requiring RoHS3 compliance. The CD74HCT153E provides extended low-temperature operation to -55°C but does not meet RoHS compliance standards. Both parts are electrically and functionally equivalent within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT153E directly replace the 74HCT153N,652 in existing designs? A: Yes, from a functional and electrical standpoint. Both parts feature identical 2 x 4:1 multiplexer circuits, 16-DIP package geometry, voltage supply range (4.5V ~ 5.5V), and output current specifications (4mA / 4mA). Compliance requirements must be evaluated separately.

Q: What is the difference in operating temperature range? A: The 74HCT153N,652 operates from -40°C to 125°C. The CD74HCT153E extends the lower limit to -55°C, providing broader low-temperature capability. Both reach 125°C at the upper limit.

Q: Are there RoHS compliance differences? A: Yes. The 74HCT153N,652 is RoHS3 compliant. The CD74HCT153E is RoHS non-compliant. Applications subject to RoHS regulations must use the NXP part.

Q: Do both parts use the same 16-DIP package? A: Yes. Both use 16-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations and PCB footprints.

Q: What is the significance of the 74HCT series designation? A: The 74HCT designation indicates high-speed CMOS logic with TTL-compatible input and output levels. Both parts belong to this series and maintain full compatibility.
