CD74HC112PW Equivalent & Substitute Parts

Part Overview

The CD74HC112PW is a dual JK-type flip-flop logic integrated circuit manufactured by Texas Instruments in a 16-TSSOP surface mount package. This device provides two independent 1-bit JK flip-flops with complementary outputs, negative edge triggering, and set/reset functionality. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain functional equivalence while offering different packaging formats, manufacturers, and in some cases, enhanced electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC112PW is determined by strict equivalence in the following parameters:

• Base product number: 74HC112
• Flip-flop type: JK Type with complementary outputs
• Number of elements: 2 independent flip-flops
• Trigger mechanism: Negative edge triggered
• Package footprint: 16-TSSOP (0.173", 4.40mm Width)
• Supply voltage range: 2V ~ 6V
• Operating temperature range: -55°C ~ 125°C or -40°C ~ 125°C
• Surface mount configuration
• RoHS3 compliance and MSL Level 1

Substitute parts may differ in packaging format (Tube vs. Tape & Reel), manufacturer, clock frequency, propagation delay, and input capacitance. These variations do not affect functional substitution when the core electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the CD74HC112PW and maintain compliance with RoHS3 and REACH requirements. Selection among substitutes should be based on the following criteria:

For direct Texas Instruments replacement: CD74HC112PWR is the active equivalent, differing only in packaging format (Tape & Reel instead of Tube). This part maintains identical electrical specifications and operating temperature range.

For Nexperia sourcing: 74HC112PW,118 is available in Tape & Reel format with enhanced clock frequency (71 MHz) and reduced input capacitance (4.6 pF). Operating temperature range is -40°C ~ 125°C, which is suitable for most industrial applications but does not extend to -55°C.

For onsemi sourcing: MC74HC112ADTG (Tube) and MC74HC112ADTR2G (Tape & Reel) offer improved propagation delay performance (21ns vs. 30ns) and are available in both packaging formats. Both maintain the full -55°C ~ 125°C operating temperature range.

All parts are ROHS3 compliant with MSL Level 1 rating and are suitable for direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC112PWR be used as a direct replacement for CD74HC112PW?

A: Yes. CD74HC112PWR is functionally identical to CD74HC112PW. The only difference is packaging format: CD74HC112PWR is supplied in Tape & Reel format while CD74HC112PW is supplied in Tube format. Both parts have identical electrical specifications, operating temperature range (-55°C ~ 125°C), and pin configuration.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for lower-volume applications and manual assembly, while Tape & Reel packaging is optimized for automated pick-and-place assembly. The electrical and functional characteristics of the component are identical; packaging choice depends on manufacturing process requirements.

Q: Are the onsemi parts (MC74HC112ADTG and MC74HC112ADTR2G) compatible with the original CD74HC112PW?

A: Yes. Both onsemi parts are functionally compatible. They provide improved propagation delay (21ns vs. 30ns) and maintain the same supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and 16-TSSOP package footprint. The faster propagation delay represents an enhancement and does not create compatibility issues.

Q: Does the Nexperia part 74HC112PW,118 have any limitations compared to the original?

A: The Nexperia part operates over a reduced temperature range (-40°C ~ 125°C vs. -55°C ~ 125°C). If your application requires operation below -40°C, this part is not suitable. Otherwise, it is fully compatible and offers enhanced clock frequency (71 MHz) and lower input capacitance (4.6 pF).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL Level 1 rating, meeting the same environmental and regulatory requirements as the original CD74HC112PW.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All substitute parts maintain identical pin configuration, supply voltage requirements (2V ~ 6V), and functional behavior. They can be used interchangeably in the same circuit design without modification.
