CD40175BPWG4

Overview

The CD40175BPWG4 is a quad D-type flip-flop from the Texas Instruments 4000B CMOS logic series. It features four independent D-type flip-flops with positive-edge triggering and an active-low master reset input. The device operates within a supply voltage range of 3V to 18V, supporting clock frequencies up to 14 MHz at 15V. It utilizes a 16-pin TSSOP surface-mount package and provides complementary outputs for each flip-flop. The component ensures low static power consumption and high noise immunity, suitable for general-purpose digital logic applications.

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards when sourcing. Confirm the package designation matches the TSSOP-16 form factor required for your PCB layout. Ensure the supplier provides official datasheets confirming the 4000B series specifications. Cross-reference the manufacturer part number to avoid confusion with non-compliant or obsolete variants.

Selection Notes

Select this component when a compact solution for multiple synchronized data storage elements is required. The TSSOP-16 package offers space efficiency compared to through-hole alternatives. Consider the 3V to 18V operating range for compatibility with various logic levels. Verify that the positive-edge triggering aligns with your system's clock timing requirements.

FAQ

What is the function of the master reset input?

The master reset input is active-low and forces all four flip-flops into a cleared state simultaneously when activated.

How does the clock triggering work in this device?

The flip-flops are triggered on the positive-going edge of the clock signal, updating the output state based on the D input level at that moment.
