CD4047BD3

Multivibrators Overview

The CD4047BD3 is a CMOS low-power monostable/astable multivibrator manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The device features propagation delays of 1000 ns, 450 ns, and 300 ns depending on conditions. It provides complementary outputs (Q and Q-bar) and includes external reset functionality. The component is housed in a hermetic ceramic dual-in-line package with 14 leads.

Multivibrators Feature Summary

• Configurable as either a monostable or astable multivibrator for flexible timing applications
• Includes external reset input for precise control over output states
• Provides both non-inverted and inverted output signals simultaneously

Multivibrators Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability components
• Precision timing circuits and pulse generation modules
• Frequency division and multiplication logic stages

Multivibrators Procurement Notes

Verify the specific suffix BD3 corresponds to the hermetic ceramic dual-in-line package (CDIP SB) when sourcing. Confirm RoHS exemption status as military-grade variants often differ from standard catalog parts. Ensure compatibility with existing board layouts designed for the 14-lead ceramic footprint before finalizing procurement orders.

Multivibrators Selection Notes

Select this part when hermetic sealing is required for harsh environments or long-term reliability. Compare against plastic DIP versions if environmental exposure is minimal. Consider the higher cost associated with ceramic packaging versus standard plastic alternatives. Verify that the 14-lead form factor fits the designated space constraints.

Multivibrators Part Context

This component belongs to the CD4047B series, which encompasses various package options including plastic DIP, SOIC, and TSSOP. The BD3 designation specifically identifies the hermetic ceramic variant intended for demanding applications. It shares core electrical characteristics with other series members but differs in physical construction and sealing methods.

Multivibrators Replacement Considerations

CD4047BF3A serves as a direct equivalent within the same manufacturer's lineup offering identical functional specifications.
