74141
DESCRIPTION
- The ’141 is a BCD-to-decimal decoder driver that is de signed to accept a 4-bit BCD code input and drive cold-cathode indicator tubes. This decoder utilizes design improvements that minimize switching transients in order to maintain a stable display. The segments and numeric designations chosen to representthedecimal numbers areshown inthe Truth Table. For binary inputs 10 through 15, the outputs are OFF. These invalid codes can be used in blanking leading ortrailing-edgezeroes in a display. The ten high performance, npn output transistors have a maximum reverse cur rent of 50 ju A at 55 V. Typical power dissipation is 55 m W.
