BD7LS17G-CTL Equivalent & Substitute Parts

Part Overview

The BD7LS17G-CTL is an active, automotive-grade logic buffer IC manufactured by Rohm Semiconductor. This non-inverting buffer operates across a wide supply voltage range of 1.65V to 5.5V and is qualified to AEC-Q100 automotive standards. The device is packaged in a 5-SSOP (SC-74A, SOT-753) surface mount configuration with Schmitt trigger input characteristics and symmetric output drive capability of 32mA for both high and low states.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and qualification status are maintained across the product line, enabling design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the BD7LS17G-CTL are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Matching Parameters:

• Package / Case: SC-74A, SOT-753
• Supplier Device Package: 5-SSOP
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C (TA)
• Current - Output High, Low: 32mA, 32mA
• Input Type: Schmitt Trigger
• Number of Elements: 1
• Number of Bits per Element: 1
• Grade: Automotive
• Qualification: AEC-Q100
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The BD7LS14G-CTL qualifies as a parametric equivalent substitute. While the logic function differs (inverting versus non-inverting), all electrical performance parameters, thermal characteristics, supply voltage range, output drive capability, and automotive qualification specifications are identical. The physical package, pin count, and environmental operating conditions remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both the BD7LS17G-CTL and BD7LS14G-CTL maintain active product status with full AEC-Q100 automotive qualification. Selection between these parts is determined by circuit logic requirements rather than electrical performance or reliability constraints.

The BD7LS17G-CTL (non-inverting buffer) is selected when output signal polarity must match input signal polarity. The BD7LS14G-CTL (inverting buffer) is selected when output signal inversion is required by the circuit design.

Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Moisture sensitivity level 3 (168 hours) applies to both parts, requiring standard handling and storage protocols for surface mount components.

The identical supply voltage range (1.65V to 5.5V), output drive capability (32mA), operating temperature range (-40°C to 125°C), and 5-SSOP package configuration ensure mechanical and electrical interchangeability at the board level, provided the logic function change is accommodated in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the BD7LS14G-CTL directly replace the BD7LS17G-CTL without circuit modification?

A: Physical and electrical substitution is possible due to identical package, pin count, supply voltage range, output drive capability, and operating temperature specifications. However, the logic function differs (inverting versus non-inverting). Circuit design must accommodate this functional difference. Direct pin-for-pin replacement without logic function adjustment will produce inverted output signals.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the BD7LS17G-CTL and BD7LS14G-CTL carry automotive grade designation and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: What is the significance of the 5-SSOP package designation?

A: The 5-SSOP (5-pin Shrink Small Outline Package) is the physical package format. Both substitute parts use the SC-74A, SOT-753 package variant, ensuring identical PCB footprint, solder pad configuration, and board assembly compatibility.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts are classified as Moisture Sensitivity Level 3 (168 hours), requiring identical handling, storage, and reflow soldering protocols to prevent moisture-induced failures.

Q: What output drive capability do these buffers provide?

A: Both the BD7LS17G-CTL and BD7LS14G-CTL provide symmetric output drive of 32mA for high state and 32mA for low state, enabling direct interface with standard logic loads across the 1.65V to 5.5V supply voltage range.

Q: Are there any supply voltage or temperature operating differences between these parts?

A: No. Both parts operate identically across the 1.65V to 5.5V supply voltage range and -40°C to 125°C operating temperature range, with Schmitt trigger input characteristics providing hysteresis for noise immunity.
