SN75472D

Buffers, Drivers, Receivers, Transceivers Overview

The SN75472D is a dual peripheral driver from the Texas Instruments SN75471 series, housed in an 8-pin SOIC (D) package. It implements a dual NAND logic function with outputs internally connected to npn transistors. Recommended operating conditions specify a supply voltage (VCC) of 4.75 V to 5.25 V and an operating temperature range of 0°C to 70°C. Absolute maximum ratings include an off-state output voltage of 70 V and continuous collector current up to 400 mA. Switching characteristics at VCC = 5 V show propagation delays ranging from 30 ns to 65 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum to confirm the exact packaging configuration, such as tube quantities for standard SOIC parts versus tape and reel options. Ensure that the selected variant matches the required moisture sensitivity level and lead finish specifications for the intended assembly process. Cross-reference the active production status to confirm availability before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select the SN75472D when a dual NAND peripheral driver is required for high-voltage applications. This component is functionally interchangeable with the SN75451B and SN75461 series but offers higher breakdown voltages at the expense of slightly slower switching speeds compared to the SN75451B. Choose this device over other logic families if the application demands medium-speed switching combined with robust high-current drive capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

The SN75472D belongs to the SN75471 through SN75473 series of dual peripheral drivers manufactured by Texas Instruments. While the SN75471 provides AND logic and the SN75473 provides OR logic, the SN75472 specifically implements NAND logic functions. These devices are characterized for operation within a standard commercial temperature range and are designed to replace older peripheral driver technologies requiring higher voltage tolerance.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN75472D is functionally interchangeable with the SN75451B and SN75461 series peripheral drivers. Designers should note that while these alternatives offer similar functionality, they may exhibit different switching speed limits and breakdown voltage characteristics compared to the SN75472D.
