CD40175BF3A

Overview

The CD40175BF3A is a CMOS quad D-type flip-flop manufactured by Texas Instruments. It features four independent D-type flip-flops with clocked inputs and complementary outputs, housed in a 16-lead hermetic dual-in-line ceramic package (F3A suffix). The device operates within a supply voltage range of 3V to 18V and supports a maximum clock frequency of 11 MHz. It is tested for quiescent current at 20V and maintains low input current specifications across the full operating temperature range.

Feature Summary

• Comprises four independent D-type flip-flops with complementary outputs
• Hermetic dual-in-line ceramic packaging suitable for high-reliability applications
• Validated quiescent current testing at elevated supply voltages

Applications

• High-reliability digital logic circuits requiring radiation or environmental hardness
• Military and aerospace electronic systems utilizing ceramic packaged components
• Industrial control systems demanding stable operation over extended temperature ranges

Procurement Notes

Verify that the specific part number includes the F3A suffix to ensure the correct hermetic ceramic package variant is procured. Confirm that the supplier provides documentation attesting to the 100% quiescent current test requirement specified in the datasheet. Ensure compatibility with existing board layouts designed for 16-lead dual-in-line ceramic packages before finalizing orders.

Selection Notes

Select this component when hermetic sealing is required for environmental protection or reliability standards. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the 11 MHz maximum clock frequency and 3V to 18V supply range to ensure alignment with system timing and power requirements.
