CD74HC192PWE4 Equivalent & Substitute Parts

Part Overview

The CD74HC192PWE4 is a decade counter integrated circuit from Texas Instruments, classified as a 4-bit logic counter with up/down counting capability. This component is designed for synchronous counting applications with a maximum count rate of 24 MHz and operates across a supply voltage range of 2 V to 6 V.

The CD74HC192PWE4 carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when the original part is no longer available through standard distribution channels or when procurement lead times are extended. Active alternatives with identical electrical and mechanical specifications ensure design continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC192PWE4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Counter, Decade (1 Element, 4 Bit)
• Counting Direction: Up and Down capability
• Count Rate: 24 MHz maximum
• Supply Voltage Range: 2 V to 6 V
• Operating Temperature Range: -55°C to 125°C
• Package Type: 16-TSSOP surface mount
• Reset Function: Asynchronous
• Timing: Synchronous
• Trigger Type: Positive Edge

The CD74HC192PWR qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction between these parts is product status and packaging format (Tape & Reel versus individual packaging).

Parameter Comparison

Engineering Selection Recommendations

The CD74HC192PWR is the direct substitute for the obsolete CD74HC192PWE4. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters.

The CD74HC192PWR carries Active product status, ensuring ongoing availability and support from the manufacturer. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The substitution is electrically and mechanically transparent. No circuit modifications, PCB layout adjustments, or firmware changes are required when transitioning from the CD74HC192PWE4 to the CD74HC192PWR.

Frequently Asked Questions (FAQ)
