CD54HC221F

The Texas Instruments CD54HC221F is a High Speed CMOS Logic Dual Monostable Multivibrator. This component features two channels and utilizes HC technology for its operation. It is designed with standard CMOS input types and push-pull output types.

The device offers balanced outputs and high speed with propagation delays between 10-50ns. It includes a positive input clamp diode for protection. The operating temperature range is specified from -55°C to 125°C, suitable for military applications. The multivibrator has a supply current of 160µA and provides output drive capabilities of IOL (max) at 5.2mA and IOH (max) at -5.2mA.

Key electrical characteristics include fanout capabilities of 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs. The HC types support operation voltages from 2V to 6V, with high noise immunity. HCT types are compatible with 4.5V to 5.5V operation and offer direct LSTTL input logic compatibility. CMOS input compatibility is also provided.

Packaged in a CDIP (J) format, this component is designed for robust performance in demanding environments. The CD54HC221F is suitable for applications requiring precise timing and pulse generation.
