CD4047BM

Overview

The CD4047BM 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 a maximum supply current of 20 uA. The device provides output currents of 4.2 mA for both high and low states. Propagation delays are specified at 1000 ns, 450 ns, and 300 ns depending on conditions. It functions reliably across an extended temperature range from -55 C to +125 C and is housed in a 14-SOIC package.

Feature Summary

• Configurable as either a monostable or astable multivibrator circuit
• CMOS technology ensures low power consumption
• Wide operating voltage range suitable for various logic levels

Applications

• Timing delay circuits
