CD40175BPW

Overview

The CD40175BPW is a quad D-type flip-flop from the Texas Instruments 4000B CMOS logic series. It features four independent edge-triggered D-type flip-flops with complementary outputs in a 16-pin TSSOP package. The device operates on a supply voltage range of 3V to 18V and supports clock frequencies up to 14 MHz. Key electrical parameters include a maximum propagation delay of 120 ns at 15V with 50pF load, output current capability of ±6.8 mA, and a static current of 4 µA. It functions within a temperature range of -55°C to 125°C.

Feature Summary

• Contains four independent positive-edge-triggered D-type flip-flops
• Provides both true and complementary outputs for each stage
• Features a master reset input to initialize all flip-flops simultaneously
• Compatible with standard 5V, 10V, and 15V logic families

Applications

• Parallel-to-serial data conversion circuits
• Decoding and demultiplexing applications
• Digital timing and sequencing control systems
• Event counting and state machine implementations

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 surface-mount package variant. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding lead finish or packaging revisions. Ensure the supplier provides valid traceability documentation for automotive or industrial grade requirements if applicable.

Selection Notes

Select this component when a compact surface-mount solution for multi-bit storage is required. Compare against through-hole PDIP alternatives if board space allows for easier prototyping. Consider the 14 MHz speed limit and 120 ns delay for high-speed timing constraints. Evaluate power consumption needs given the low static current characteristic of the CMOS technology.

Part Context

This part belongs to the CD40175B family of quad D-type flip-flops. It serves as the surface-mount equivalent to the CD40175BE (PDIP) and CD40175BNSR (SOIC) variants. The 4000B series is designed for general-purpose digital logic applications requiring reliable data storage and transfer capabilities across wide voltage ranges.

FAQ

What is the trigger type for the CD40175BPW?

The flip-flops are triggered on the positive-going edge of the clock signal.

Does the device have an enable input?

No, the CD40175BPW does not feature a dedicated clock enable pin; it relies on the clock and reset inputs for operation.
