74F245PC Equivalent & Substitute Parts

Part Overview

The 74F245PC is a non-inverting transceiver logic integrated circuit manufactured by onsemi, designed for 8-bit bidirectional data transfer with 3-state output capability. This component operates within a 4.5V to 5.5V supply voltage range and is housed in a 20-pin DIP package suitable for through-hole mounting applications.

The 74F245PC is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where original stock becomes depleted.

Substitute Part Grouping Explanation

Substitute parts for the 74F245PC are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 3mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)
• Mounting Type: Through Hole
• Package / Case: 20-DIP (0.300", 7.62mm)
• Supplier Device Package: 20-PDIP

Two substitute parts meet these criteria:

1. SN74F245N (Texas Instruments) - Direct manufacturer equivalent with identical series designation and electrical specifications
2. SN74BCT245N (Texas Instruments) - Parametric equivalent with identical electrical performance and package configuration, differing only in series designation (74BCT vs 74F)

Parameter Comparison

Engineering Selection Recommendations

Both SN74F245N and SN74BCT245N are suitable substitutes for the obsolete 74F245PC based on complete electrical and mechanical parameter equivalence.

SN74F245N is the direct series equivalent, maintaining identical 74F logic family designation. This part carries active product status from Texas Instruments and holds ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

SN74BCT245N is a parametric equivalent within the 74BCT logic family, also maintaining active product status and ROHS3 compliance. The 74BCT series represents an alternative logic family with identical electrical performance specifications for this application.

Both parts are available in tube packaging and demonstrate equivalent inventory levels suitable for production requirements. Selection between these two substitutes depends on design documentation requirements and existing component qualification procedures within your organization.

Frequently Asked Questions (FAQ)

Q: Can SN74F245N directly replace 74F245PC without circuit modification?

A: Yes. SN74F245N is a direct equivalent with identical electrical specifications, output characteristics, supply voltage range, operating temperature range, and 20-PDIP package configuration. No circuit modifications are required.

Q: What is the difference between SN74F245N and SN74BCT245N?

A: Both parts are parametric equivalents with identical electrical performance. The primary difference is the logic family designation: 74F versus 74BCT. Both operate within the same voltage supply range (4.5V ~ 5.5V), deliver identical output currents (3mA high, 24mA low), and are housed in the same 20-PDIP package. Selection depends on design documentation and component qualification procedures.

Q: Are the substitute parts available in the same packaging format?

A: Both SN74F245N and SN74BCT245N are supplied in tube packaging, which differs from the original 74F245PC packaging specification. Both maintain the identical 20-PDIP physical package configuration required for through-hole mounting applications.

Q: Do the substitute parts meet current regulatory requirements?

A: Yes. Both SN74F245N and SN74BCT245N carry ROHS3 compliance certification and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the inventory status of these substitute parts?

A: SN74F245N has 2260 pieces available as new original stock. SN74BCT245N has 2000 pieces available as new original stock. Both parts maintain active product status with Texas Instruments.
